File Locks and SMB shares with ML

I've been doing a lot of research on SMB and the way it locks files during access. I've made a lot of ground work in my research but could use a little further assistance from this support community.
The symptom is simple to explain: Users are occasionally being prompt for a username and password when attempting to rename or move files and folders.
After doing some research on this topic, I have discovered that there is a direct relationship to files being open on the server at the time the user is attempting to rename or move the folder. The following thread, albiet old, appears to have nailed the problem on the head http://arstechnica.com/civis/viewtopic.php?p=24558131. In particular, there appears to be file locking happening when preview is turned on through the finder. I've had all users remove preview from their Macs and this appears to have helped reduce the occurances of the password prompt, but has not completly solved the problem. This is also a work around, not a fix.
I've been using a series of command to help me trace the problem including openfile.exe on the Windows 2012 Storage Server (sharing the files via smb only) to discover who has what files open on the server, and the lsof command on the client workstations to discover what process has the file open. So far, the finder is consistently the only thing with the file open... even with the finder preview turned off. I've also found that the "open file" is simply the fact that the offending users Mac has a finder window with just the folder open (none of the files within the folder or previews open).
Is the real solution to simply close all finder windows when you're done working in a folder, or is there more that anyone can think of to help me find out exactly what is holding the file lock? Is this a known bug in the SMB implementation of ML? Can we expect to see a fix with Mavericks which will now be using SMB2.0?
Any help or information anyone can provide would be greatly appreciated. I have a bunch of documentation on this issue and would be happy to share. Please let me know if anyone needs any additional details.

Hello all - many apologies for my delay in posting here; and Squiggle, thanks for the second-hand nudge. As Stephen said we have been testing a solution concerning a setting in Finder's view options for the last few months, and these seem to have solved the issue in hand.
Essentially, we found that Finder was holding files open whenever the 'Show Icon Preview' option was set, on any of the four folder views, on any client machine accessing the share. Below is a piece of documentation I wrote up for our Service desk explaining how to diagnose and manually fix this issue on the client:
        - In Finder, open any folder
        - Click on the cog icon and select 'show view options.' Check that, in the dialogue box which appears, the 'Show icon preview' box is not checked. Click the other three Finder views and check it's turned off here too.
        - Click 'Use as Defaults'
In order to make this change remotely on multiple machines, you will need to change the clients' com.apple.plist files, and set every instance of the <showIconPreview> key to <False>. This is nested within several key / dictionary pairs in com.apple.finder.plist, once under <standardViewOptions> and thrice within <standardViewSettings>. As Stephen has already mentioned, the fact that this key is nestled deep within compound dictionaries seems to render them untouchable by defaults, though I would be very happy to be corrected on this.
How you push this change out will depend on your management system. We had been using Casper to
to create a managed preference pertaining to <standardViewOptions> and <standardViewSettings> within com.apple.finder.plist. These contained as values the entire dictionary associated with these keys, with the value for each <showIconPreview> set to false. This was then applied at a User Enforced Level (running every logon after Finder has set up the system defaults).
As a side note, I have found that certain machines (Such as the 10.8.3 machine I'm working on now) contain a key named <FK_StandardViewSettings>, which I have been unable to ascertain the purpose or origination of. These don't seem to affect the fix, so we've left them alone.
Irritatingly, Casper has dropped support for custom Managed Preferences in their latest release, so this problem has now resurfaced. I will keep this page updated with any fixes or workarounds I find.
Hope that helps,
Josh Smith

MS Office file locking on SMB share

I have both Windows and Mac clients accessing the same SMB share. There are file locking issues with Microsoft Office files, eg Excel.
Scenario 1:
1) PC User connects to the share and opens file test.xls. The PC user gets read/write access.
2) Mac user connects to the share and opens file test.xls. The file opens read-only. This is the desired behavior.
Scenario 2 (the problem):
1) Mac user connects to the share and opens file test.xls. The Mac user gets read/write access.
2) PC user connects to the share and tries to access file test.xls. Access fails with the following error: "Cannot access 'test.xls'".
A few details:
The share is on a NAS (network-attached-storage) device, although I can reproduce the same behavior on a windows server or Samba server as well.
The Macs are OSX 10.4 or 10.3 with Office 2004
The PCs are XP SP2 with Office XP Pro
My storage vendor says this is a 'Mac issue'. Any thoughts?
Thanks!
Various Mac OS X (10.4.6)

There are plenty of free ways to view at MS Office, but I don't think there are any to let you edit it. Most free apps are free for a reason (luring people in for purchases/upgrades, or supporting a commercial company as a portal, or as public services) - a dedicated professional app such as this is going to cost you less than 10 dollars.

OSX 10.8 and SMB Shares with Access Based Enumeration.

Hello,
I've been working on a bit of a problem related to some SMB Shares on Windows Server 2012 with Access Based Enumeration with Mac OSX 10.8 & 10.9.
Basically, we have one network share that mounts for all of our Students & Faculty on campus. Then, based on which security group the user is inside of in Active Directory, they gain access and visibility to different folders. (Basically, if they are members of the graphic design department, they get access to the Graphic Design's folder). All of that is working fine, no problems. From there we have 3 folders that branch off. We have a Distribution, an Open, and a Dropbox folder.
Distribution is setup as a spot for instructors to have full access, students have read access, They're able to drop files into this locations, to distribute them to their students. This folder is working fine, no problems.
Open is setup with everyone read/write access across the board. This folder is setup for students to share data to each other, work on projects, etc. This folder is working as intended, no problems.
Dropbox is the only folder we're having trouble with, i'm assuming because it's settings are the most complex out of the three. The purpose of the drop box is for students to have read/write control over their own content, but not others, and instructors to have read/write over this entire folder.
Now that I've laid out our Setup, the problem we've encountered, is ONLY occurring inside of the Dropbox folder. When I try to Drag/Drop OR Copy/Paste from another location on the computer into the Dropbox folder, I get a permission error. HOWEVER, if I have a file open, and I click "save as" browse to the dropbox folder, I can save the file into that location without any trouble. Also, on our windows computers, with the same exact users, drag/drop & Copy/Paste work normally.
Things I've Tried:
Disabling the .DS_Store - I figured in the drop box, the .DS_Store would be created by the first user who copied a file in, then subsequent users would not have access to the .DS_Store.
CIFS/SMB1 - I've read that SMB2 can cause some trouble while connecting to SMB Shares, so I tried both connecting via CIFS, and also by forcing back to SMB1, with no fix.
Am I missing something with this? I've read a lot about people having trouble connecting to SMB Shares, but for us it had not been a problem up until this point. Does anyone know what a possible fix might be for this? I'm sifting through internet searches right now, trying to find a solution, however MOST of the responses I see are regarding the two things I've already tried.
Any suggestions would be greatly appreciated.
Thanks!
iMac, OS X Mountain Lion (10.8.5)

Just thought I'd post this in case it helps someone. This could be the same problem we have (had) here so try this:
When it asks for name and password put this in the name field: sharename\name
So if the share is called "WWW" and your login name is "Bob" you'd put "www\Bob" in the name field and then normal password in the password field.
Works perfectly for us. I cant remember when it started 10.7 or 10.8 but this was the only solution. Hope it helps someone else!

Using single SMB share with multiple Hyper-V clusters

Hello,
I'm trying to find out if I can use a single SMB share with multiple Hyper-V Clusters. Looking at:
How to Assign SMB 3.0 File Shares to Hyper-V Hosts and Clusters in VMM
I think it's possible. Since the File Server is going to handle the file locking it shouldn't be a problem.
Has anyone tried that?
Thank you in advance!

Hello,
I'm not sure that's possible, I get this from this statement:"Assign the share—Assign
the share to a virtual machine host or cluster."
Even if it worked I wouldn't do that. Why don't you just create multiple shares?

Windows Server 2012: SMB share with transparent failover

Have a nice day to all!
I have 2 HP Proliant DL380P Gen8 servers containing 8 x 1TB disks (with P420i HP Smart Array RAID Controller) in each server.
So, there are 2 arrays on every server:
1. 2 x 1TB in RAID1 (+1 disk for hot swap) - system volume
2. 5 x 1TB in RAID5 (+1 disk for hot swap) - data volume
And I installed Windows Server 2012 Standard on each server.
Than I created a failover two-nodes cluster.
And now I want to create a SMB share with transparent failover for all the second (data) volume (it's about 3.3TB in RAID5 array). How just can I reach this goal? I'm going to use it in future for Hyper-V VMs, so, the main reqirement is powered-on and working
VMs even if one node of SMB share cluster is failed.
I wasn't able to see my volumes in failover cluster manager. I tried to create iSCSI targets, storage pools, virtual disks, etc. but no luck. My failover cluster manager can't see it to create SMB share!
Can anyone advice me something?
Thanks in advance!

You need to have your storage you want to export as being a shared storage visible to your cluster (part of CSV). Then you'll configure failover file shares using content accessible from both cluster nodes. Refer to this manual for diagrams (ignore StarWind
and replace it logically with your existing shared storage you've used to create your cluster):
http://www.starwindsoftware.com/configuring-ha-file-server-on-windows-server-2012-for-smb-nas
Also see these manuals from MS on how to create failover file server:
http://technet.microsoft.com/en-us/library/cc753969.aspx
http://technet.microsoft.com/en-us/library/cc731844(v=ws.10).aspx
http://blogs.technet.com/b/askcore/archive/2010/08/19/working-with-file-shares-in-windows-server-2008-r2-failover-clusters.aspx
However if you want to use existing storage located on the both nodes you're out of luck. Microsoft does not provide anything representing local DAS to the cluster nodes. If you want to use existing DAS then you'll have to stick with a third-party product
like StarWind, SteelEye or DataCore. To create something like in this picture:
So you'll have a configuration with only two nodes, no physical shared hardware (SAS JBOD, FC or iSCSI) and vSAN. Refer to this manual:
http://www.starwindsoftware.com/ns-configuring-ha-file-server-for-smb-nas
Hope this helped :)

How to find PG.xml file name and path associated with a FUNCTION

Hi,
I am having a function:IRC_VIS_HOME_PAGE with Web HTML value as below:
OA.jsp?akRegionCode=IRC_VIS_HOME_PAGE&akRegionApplicationId=800&OAPB=IRC_BRAND
How to find PG.xml file name and path assoicated with above funtion.
Thanks,
ashok

Ashok,
Function IRC_VIS_HOME_PAGE will have 2 parameter defined for it which are OASF and OAHP where
OASF=<SelectedFunctionName> - this tells the Framework to select this function in the given "Home Page" menu context.
OAHP=<HomePageMenuName> - this is used ONLY with the OASF parameter, and it is used to establish the current menu context. It should point to a "Home Page" menu.

Trouble with wireless n and smb shares

I have a bit of a per-plexer here.
I have a personal mac that up until a little while ago, ran 1.5.8 flawlessly for six months since i had it.
This included a lot of mounting my windows 7 file server and watching movies or listening to music over wireless G. Every night in fact I would fall asleep to a movie, then wake up and play some music from my music folder on the same server.
The battery would die nightly of course. Morning, charge it up with some music on.
I picked up a copy of snow leopard upgrade for 30 bucks when it was released or there about and installed it. Went fine and I continued happily using the machine for about 2 months.
Then I bought a belkin wireless N gigabit router, to replace my wrt54g. It worked alright and I continued my daily/nightly routine, watch a movie, sleep, listen to music.
However the first morning, and every morning subsequently there after I have run in to a pain-in-the-butt problem.
I awoke to find, like always, my server shares still mounted (or at least they appeared to be). But opening any of them would present a blank finder window, like no files were available.
Unmounting and re-mounting the shares would fail, with a message saying unable to connect to the PC.
So, what do you do next? I reboot. My programs close, the dock, finder, my background turns to the blue solid.
System stops re-booting... it sits here, with a plain cursor and I am unable to do anything but hard-power it off.
After a hard-reboot,everything functions normally until it hibernates or sleeps with the samba shares.
I took the router back and got a dlink n/gigabit router instead, cussing out belkin on my way to the store. No change!
So I reinstalled (I didn't even archive, i just blew it away) - installed 10.5.8 again, upgraded to SL, and connected to my wireless. I can still reproduce the issue.
So, i'm bummed, i've tried a lot of things I wont bother listing here but one more important detail i wanted to add is:
I work at a company that has blanket wireless b/g coverage using multiple access points and a controller to do load balancing and access point switching.
Recently, we got a few N access points from the provider and I set them up around the office in a new, isolated SSID on the subnet i do my work on. Using WPA2 Psk, like at home.
So, now to be fair I've got a slightly-newer mac at the office, same unibody but late 2009 instead of early 2009 (sd slot instead of express slot). I threw SL on it, and connected to the new SSID i setup and finally connected to our netapp and left for the night.
Come in in the morning and I can reproduce the issue on the work mac.
So, two different macs, 2 very different N wireless networks and 2 different file server platforms. But same prob, **** thing chokes overnight.
I have been able to reproduce this issue with a slough of late 2009 macs at the office now, as I handed out the SSID key to those with SL as my unwitting test subjects. Everyone's coming up with the same problem.
Has anyone out there run in to this? It's such a huge issue i'm surprised i can't find anymore information about it!
Thanks,
Josh

I took a look at the logs and copy and pasted a lot, these are a few before and many from AFTER the hibernation last night.

Confusion of aliases made for two SMB shares with same folder name

I have a SMB file server here which provides me with a Departmental personal home filestore and also a Departmental personal web filestore. The name of the folder is the same in each case - my Departmental user name. If I check the Finder Preference 'Show these items on the desktop' for 'Connected servers', I can use the Finder's 'Connect to Server' for each - smb://webhome/john and smb://home/john - to make each of them appear on my desktop as 'john'.
It's rather confusing to have to remember that (say) the upper 'john' is my home filestore and the lower one is my web filestore, so I use Finder 'Make Alias' (e.g. via right click on each when selected') to create two aliases I can name 'web john' and 'home john'.
Alas, each alias always points to the same (apparently randomly selected) share!
This looks like a bug to me. I've tried unchecking the Finder 'Connected servers' preference, and then the shares appear under folder 'SHARE' - where I cannot create any aliases at all; I get the error message 'Operation could not be completed (Error -8058)'.
Reader, do you know of a work-around which will let me distinguish on my desktop between my two identically-named folders from different shares? Alas, I have no power to change the names of the original folders.

I should have said that one cannot rename the share icons in the usual way. Not being able to do this is the real bug here. If I'd been able to do this I wouldn't have need to try to create aliases, of course.

Problems copying files to a SMB share.

Hello,
Having some odd issues since moving to 10.6. It appears to be a combination of two problems.
We are in a PC based Active Directory environment. The Mac is bound to the AD and has a Mobile account configured. The problem is with copying files to the network Home folder.
On attempting to copy a file to the network drive I received a "The operation can't be completed because you don't have permission to access some of the items" error. This only seems to effect some files. I checked the permissions on both the file I was attempting to copy and the destination folder. I had full read/write access to both.
I attempted to copy the file with the terminal and got an error that I was unable to copy the extended file attributes of the file as I did not have permission.
Using the xattr command I could see that the file had the com.apple.TextEncoding attribute. I used the xattr -d command to delete the attribute and I was then able to copy the file with the Finder. Another file I tested that I could not copy had the com.apple.FinderInfo attribute. Deleting this attribute also allowed me to copy the file.
It seems that any file with extended file attributes in 10.6 cannot be copied to our SMB shares. I have tested this on all of our 10.6 Macs with exactly the same result. 10.5 has not had the same problem.
Now for the second problem. After copying the file as part of the testing I attempted to copy the same file over and replace the existing file and got the error "The Finder can't complete the operation because some data in "" can't be read or written (Error code -36)". I attempted to this a number of times and found that approx 50% of the time it does copy with no error. Checking the Console gives me the following message for the times it does give an error :
27/10/09 4:03:27 PM /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder[153] Allocator race detected: transaction is not verified for -101/2 - test7.txt
Any light that can be shone on this issue would be great. This means for us that OS X 10.6 is fundamentally broken and can't be installed on any machines.

According to Craig, a poster on the microsoft.public.mac.office newsgroup:
Changing the owner of the share to NETWORK SERVICE will solve the problem. I have tested this on a test share I set up during troubleshooting and it works! I have told my MS support rep about the workaround and she was going to spread it around. She mentioned that Apple appears to have a fix in the works but not to expect it to be released until February!

Windows 2012 Standard File Server Clustering SMB Share Error: Access is denied.

Hi All,
My setup consist of 2 nodes clustered with File Server role. I can successfully failover role to either node with no issues. But if I try to modify the permissions of any file share on my file server cluster I get the following error: Error
Occurred while updating an SMB share: Access is denied. Access is denied.
Now I played around with the permissions on these shares and noticed that when I add the "everyone" group to these shares with change permissions I can successfully modify the shares with no errors. If I removed the "everyone" group
I get the error. So to tell its like some service or account needs permission to these shares to be able to modify them. I don't want to keep "everyone" group on these shares. Can anyone please shed some light on what group, user,
or service account needs permissions on these shared in order for me to modify these SMB shares without getting Access is denied. Thanks

Hi,
It seems your account don’t have the enough right to modify this clustered folder permission.

Smb share with neotv

Hi
I have a problem with the smb share from lion.
on my old imac i had a networkshare with all my videos and connected with a netgear neotv. with my new imac with the lion system i cant look the films anymore. the smb share is installed and the permissons set. the netgear device sees the directory from the file but can not play the videos. there comes an error that the location is not accesible.
I have asked Netgear and they told me that the problem is the new smb version.
have anybody any idea how to fix or workaround this problem?
Best regards
Adrian

Please send the output of `zfs get sharesmb` for the datataset you want to share.

SMB Share with Access Based Enumeration & Mac OSX 10.8/10.9

Hello,
I've been working on a bit of a problem related to some SMB Shares on Windows Server 2012 with Access Based Enumeration with Mac OSX 10.8 & 10.9.
Basically, we have one network share that mounts for all of our Students & Faculty on campus. Then, based on which security group the user is inside of in Active Directory, they gain access and visibility to different folders. (Basically, if they are members of the graphic design department, they get access to the Graphic Design's folder). All of that is working fine, no problems. From there we have 3 folders that branch off. We have a Distribution, an Open, and a Dropbox folder.
Distribution is setup as a spot for instructors to have full access, students have read access, They're able to drop files into this locations, to distribute them to their students. This folder is working fine, no problems.
Open is setup with everyone read/write access across the board. This folder is setup for students to share data to each other, work on projects, etc. This folder is working as intended, no problems.
Dropbox is the only folder we're having trouble with, i'm assuming because it's settings are the most complex out of the three. The purpose of the drop box is for students to have read/write control over their own content, but not others, and instructors to have read/write over this entire folder.
Now that I've laid out our Setup, the problem we've encountered, is ONLY occurring inside of the Dropbox folder. When I try to Drag/Drop OR Copy/Paste from another location on the computer into the Dropbox folder, I get a permission error. HOWEVER, if I have a file open, and I click "save as" browse to the dropbox folder, I can save the file into that location without any trouble. Also, on our windows computers, with the same exact users, drag/drop & Copy/Paste work normally.
Things I've Tried:
Disabling the .DS_Store - I figured in the drop box, the .DS_Store would be created by the first user who copied a file in, then subsequent users would not have access to the .DS_Store.
CIFS/SMB1 - I've read that SMB2 can cause some trouble while connecting to SMB Shares, so I tried both connecting via CIFS, and also by forcing back to SMB1, with no fix.
Am I missing something with this? I've read a lot about people having trouble connecting to SMB Shares, but for us it had not been a problem up until this point. Does anyone know what a possible fix might be for this? I'm sifting through internet searches right now, trying to find a solution, however MOST of the responses I see are regarding the two things I've already tried.
Any suggestions would be greatly appreciated.
Thanks!

hi everybody
I really need some help so here is a little up !
thanks !

Can't open Office 2011 files on CIFS/SMB shares.

I can't open Excel or Word documents if they are opened from a network CIFS/SMB share. Excel returns something like "could not open because some content is unreadable" and offers to repair the document. Word just questions if the document is corrupt and errors out too. If I drag the same document to my desktop, it opens just fine. Is something broken with SMB? I'm running the latest Yosemite (10.10) upgraded from Mavericks 10.9.5. Office 2011 is completely updated too.

I am having what I think is a intimately related problem, but which is somewhat more aggravated. I have a server set up using FreeNAS 9.3, which is configured as Windows+CIFS (SMB) in order to facilitate for Windows-based computers to join. Permissions are consequently set-up with a Windows client (a MBP running Win7 in Bootcamp). Everything works fine as far as access and file transfer goes, but using any application changes the experience.
Just to be explicit, my problem is not only related to MS Office files, but also to PDFs and PNGs (I assume it is related to ALL files, but those are the ones I have tested). The problem arises, as for you other, when I try to save from within the application after I have altered the file's content. I get different messages depending on the application, but they all share the problem of not being able to save and that they after showing that error message, change the filename on the server (in the case of Word, it becomes 'Word work file L_2.tmp').
I have tried connecting to the server using Win7 and changing the same file and that works just as intended. I have also tried setting up a dataset (folder) on the server with only AFP and Mac settings and that works fine, but as Apple shifted to SMB from Mavericks it is not that enticing to set up a server with a dying technology, which is why I insist on getting the Windows/SMB share to work.
I have also tried the tips provided in this thread:
http://arstechnica.com/civis/viewtopic.php?f=19&t=1253789
1. smb://FreeNAS
2. cifs://FreeNAS (should force SMB1)
3. smb://FreeNAS:139 (should force connection over Netbios instead of TCP/IP)
None works.
I have checked the log files /var/log/samba4/log.smbd and /var/log/messages on the server, but they do not provide any error messages in this respect.
Based on declure's suggestion, I have copied a new Word file to the server -> disconnected from the server -> reconnected using 'cifs://servername' -> opened the Word file and tried to save it -> same error message ("Word cannot save this document due to a naming or permissions error on the destination volume."). As this works in Win7 it seems as the real problem resides not with the application (or is Office for mac faulty?), but with OSX.
Any constructive suggestions would be appreciated as I really would want this to work using SMB.

Windows 7 SP1 client file lock on network share hosted ny WIndows 2012 Server

Hello
I have one strange problem after migration from Windows 2003 Server to Windows 2012 Server R2 Standard.
All migration tasks went well but two things do not work.
In Computer Management you have The Opened Files feature and if you open any file that is located on the network share hosted by Windows 2012 R2 form Windows 7 SP1 and then close it
it remains open in the Opened Files tab (even if you wait an hour). There is no problem with Windows XP SP3. The issue exist only with Windows 7.
The session view of sessions to the file server do not work. If I try to open it I get the message that the application is not responding.
Can someone help me with that ?
About the environment:
It is one server Domain migrated form 2003 to 2012R2.
The domain and forest level was raised to 2012 R2.
I have made clean install of Windows 2012 R2 and then migrated AD.
Best Regards
Sebastian Sala

Hi Sebastian,
>>There is no problem with Windows XP SP3. The issue exist only with Windows 7.
T>>he session view of sessions to the file server do not work. If I try to open it I get the message that the application is not responding.
Based on the description, please check event logs in Event Viewer to see if there were some related events logged. Besides, does this phenomenon happen all Windows 7 clients? We can try to restart the client to see if it helps.
Best regards,
Frank Shen

Finder not showing files in an SMB share

Ok, I think I know what I need to do, but i'm not sure where to look essentially. I have a user in my office that connects to a share on a PC file server called Community. When looking at the share in finder it seems to be bugged, and it shows like an old cached view of what the share USED to look like. If I open a terminal and do an ls everything shows up like normal. The way I've been able to temporarily unbugg this is by clicking on Go->Go to folder and then telling it to go to \volumes\community\myfolder and then it corrects the view and shows the correct list of folders. But the next time she boots her mac and connects to the share - old view again. Is there a file for finder that is caching this info in her profile that I need to delete somewhere? This seems to be the issue, but I'm not sure where to look for this. Worse comes to worse I suppose I could always give her a clean profile on her mac, but I hate to do that for something so trivial.
(Just to note here, there's no hidden files or anything - If we go to another PC or Mac everything shows up fine, first try, no problem. It's just this one machine having this issue)

giving this topic a bump. i've tried the same share via AFP and SMB, both have shown files before, but now only show folders in Finder.
incidentally, i tried mounting the same share using NFS and it works, all files and folders are shown in Finder.
in either case, all files and folders show up from Terminal.
