Shared volume file transfers fail and kill my RAID. Help!

Hi all,
I'm not an IT expert by any stretch, so please go easy if my questions are stupid. First, a quick rundown of my setup:
Xserve Quad with 10.5.2
Areca 1220ML RAID card (this is a hardware RAID card with 256MB)
NORCO 1220DS 8-drive RAID box
Multiple sharepoints all coming from RAID box (one 4-drive RAID5 and several single drive passthroughs)
Trunked 2GB connections to most client machines, client connect using AFP
I have been experiencing potential signs of the issues others are having here (AFP etc.) but the most troubling is that occasionally, when attempting to move a folder from one sharepoint to another (whether doing this from a client machine or on the server directly) or when moving files from a client machine to the sharepoint, finder will hang after moving 84kb or so, I get the beachball, and end up having no choice but to force reboot the system. Upon restart, sometimes the RAID volumes are all present and working, but several times the drives just disappeared outright and the admin tool for the RAID card says the RAID volume/passthrough drive has failed. I have to rebuild them and lose every ounce of data. Yay!
Is this a familiar/known type of problem to anyone out there? I am not quick to assume the card is at fault, as it is a reasonably expensive hardware-based RAID card and its drivers are built in to with Leopard Server 10.5 (there is even speculation that Apple's own RAID card is based on Areca's) which tells me they've passed a quality test to some degree.
This problem doesn't always happen, and there are times where it will happily transfer large quantities of giant files with no problems. It usually seems to glitch out when some time has passed since the last attempted file transfer, which makes me wonder if this might be part of the dreaded AFP disconnect issues.

I just wanted to close this question out and let the community know that I isolated the problem down to my RAID box, the NORCO DS-1240. These things have been noted to have build issues, including the excessive use of solder and other issues that lead to shorting out etc.
After hours in tech support land, I replaced it with a Enhance Technologies EnhanceBox and everything now works beautifully.

I use Outlook for my email, and about 90% of the time when I want to attach a pdf or jpg file it failes and andout 50% of the time when I'm trying to send a standered text email I also failes and the email masage crashs. The only way I can get my Outlook to work is if I switch to Firefox. I would rater not have to swich all my bookmarks over to Firefox.
Has any one eals had this problem?

That's an Outlook issue. You'll probably get better responses posting on the Office for Mac forums.

Firefox 3.6 requires at least OS X 10.4, the last version of Firefox that worked on OS X 10.3.9 was Firefox 2.0.0.20 which is available from ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/2.0.0.20/mac/

IChat File Transfers fail on 10.7.x Server

I started this Post over in the iChat FORUM, and it was suggested I post here too: https://discussions.apple.com/thread/3840760
I have an OS X Server 10.6 setup with iChat and it works perfectly.
This Mac is connected directly to the WWW, no firewall.
I have an OS X Server 10.7 setup with iChat and it works perfectly EXCEPT for File Transfers
This Mac is connected directly to the WWW, with a Netgear FVS336Gv2.
I have opened all the correct ports for TCP & UDP and mapped them to my OSX Server 10.7 at 192.168.2.100
I am totally stumped now, why should JUST file transfers do not work?
This iChat OSX Server 10.7 is setup for people on the same server, using the same domain.
File Transfer in iChat WORKS on the internal network OK :-)
File Transfer in iChat DOESN'T WORK on external network :-(
Here is a screenshot of my routers portforwarding...
http://www.jrpmedia.co.uk/shared/Remote%20Desktop%20Picture.jpg

If you are having intermittent or sporadic file transfer problems.. or experiencing only one way file transfers on a local lan:
Pick One:
5222 TCP Client authenticates and sends txt messages to the Server on this port.(Apparently TLS if avaialble)
5223 TCP Client authenticates and sends txt messages to the Server on this port.(Legacy Forced SSL)
Enable these:
16402 UDP ClientA communicates with ClientB directly on this port for video chat. (Apparently SIP)
7777 TCP - Screwy file transfer proxy port.
From what I can tell about file transfers:
File transfer proxy.
ClientA tells Server to tell ClientB that there is a file waiting to be picked up at ClientA on a "randomly" assigned ClientA port.
ClientB fails to directly connnect to ClientB on this "randomly" chosen port.
ClientA fails then reverts to proxy mode. KEY STEP
ClientA sends the file to the Server on this 7777 tcp port.
Server proxies the file to the ClientB.
Warning: Having too many directly connectable ports between ClientA and ClientB can cause confusing communcation failures for file transfers between iChat/Messages clients. If one of the clients is able to establish partial communication, it will not properly fail then revert to proxy mode.
We don't want to open a crap load of ports for file transfer and therefore prefer to have it transfer files via the server proxy port
Communication flow required to get this to go:
from clientA to server 5222-5223 (pick one), 7777 for auth and file transfer
from clientB to server 5222-5223 (pick one), 7777 for auth and file transfer
from client to client 16402 for video
The above solved our screwy partially working file transfers... hopefully this helps someone.

Sharing linked files between mac and pc

Dear Community and AI Support,
My team is trying to share AI files between Macs and PCs. That works fine until we have Linked assets. Once we have linked assets, AI either forgets to, or is unable to, let us relink more than one of the linked files. We can't edit the links or even delete them. The linked files are just ignored, leaving the file half empty.
We've tried hacking the paths directly in the .AI file, hoping to eventually write a perl script to help us switch back and forth. but no luck. We assume there is a checksum or crc code or hash, etc..., as AI won't even try to open the file after that.
But to clarify the issue. here is an example of the Mac and PC links we need to switch between using an excerpt from the AI file. These are valid, working directories on both platforms.

ooohhhhh very interesting. I did a find and replace on all the strings, but no dice. I didn't think to look at those types of data. But now that you have mentioned it, perhaps I'll do a diff on the same file saved on both platforms to see what has been changed. Should have already thought of it, but your note has made me check my assumptions.

Copying large directory fails (and kills connection)

here's my scenario: i've acquired a brand new macbook,
and i tried to copy my iPhoto library (27GB) off my old mac mini.
i've tried via firewire and via wi-fi, and both times the
copy stops part way through (after about 15-20 mins)
saying 'The Finder cannot complete
the operation because some data in "" could not be read or written'
with 'Error code -36'.
the Mac mini is running mac os 10.4.11; the macbook is running 10.5.2.
i've verified that the entire directory can be copied ok, i.e. there's
no disk error, by duplicating it on the source machine (no problem).
after this occurrence, the shared file connection
between the two machines goes away and cannot be restarted (it says
'Connection Failed").
the strange thing is that the network connection between the two machines
continues to function just fine (verified with an ssh connection that continues
to work no problem).
here's what i found in the console log:

I did some more additional testing , 4 files
200mb
250mb
300mb
434 mb .... all MOV, imovie made files (not that it should matter)... but
1- selecting all the files and dragging to the nas share, the copy fails 20% of the way
2- selecting each file, 200, 250 went fine , the 300 went after 3 tries, and i never got the 434 to go
3 - switched to FTP, filezilla client on MAC and Filezilla Server on Windows, uploaded all files without a problem, with 2 open connections at a time

Issues when sharing InDesign files across Mac and PC?

I'm looking for advise regarding cross platform use of the same InDesign files. We'll be working on 1000+ files with high resolution images. One designer works on a Mac and the other on a PC. We run the same version of InDesign. So far we are finding some (not all) fonts have issues where a PC font has to be replaced by the Mac equivalent and this often means the text box size has to change. When finished the files will be handed over to a fabricator.
Should we be getting a 2nd Mac to replace the PC or is this cross platform sharing going to work without long term issues down the road?
Thank you.

Please, let's not let this get into a platform war.
There's no reason to buy another computer to collaborate unless one of your users is unhappy with the platform they use now, and then the deciding factor should be personal choice. One is decidedly not better than the other from any technical standpoint as far as working in Adobe applications. If you want to cooperate with other users it's best that everyone have the same version of ID, which you've already said is the case, so the only point of conflict is cross-platform sharing, and the only hangups there are fonts and a few third party plugins that might be available only on one platform. If you stick to OpenType fonts, fonts be come a non-issue, and if you don't have OpenType, Stick withthe PD fonts for what becomes a minor nuisance on the Mac side. As far as plugins, nothing you can do if you need a one-platform release to do the work on both sides, but most third-pary plugins are friendly enough that you can stillopen the file with missing plugins on the other end if necessary and don't need the functionality to do your work.

LDOM Disk IO file transfers, compression and discompression issues

We are currently moving to an ldom environment a lot of our oracle database servers, an issue we have come across is when compressing/uncomprssing or transferring files from within our ldoms everything is slow. If I run the same operations from a zone everything runs faster. Our ldoms are all hosted on 3 t5220s with a 2540 disk array back end. The zones are running on M4000 with the same disk array backend. All our ldoms started with 4 vcpu and 4MB. We have 5-8 ldoms on each t5220.When running compress pmap -x for PID show 2.5Mb used from 4Mb, mpstat shows idl time on 8 vcpu >60% zpool iostat -v shows max reads 270 writes 70 bandwidth upto read 12M write 5M. I tried increasing memory and vcpus but didnt expect it to make a difference and it didnt. This is affecting our backup times. Compressing a 10GB oracle backup file takes 32 minutes uncompressing 20 minutes on the ldoms on the zones the time is a 1/3 still slow but managable. Solaris 10u7 LDOM 1.2 Any ideas on what to check next?

After further investigation it seems it is a feature of the t5220's I also tried this on a basic OS install on a t5120 an got similar performance output. The t5*** series is good for multi threading apps but not very powerful for single thread apps. Apparently compress/uncompress gzip all use single threads which is why they are slow, I need to find a multi thread compression tool approved by SUN I have found a pbzip2 and need to check it out.If anyone is the wiser please advise Any other suggestions would be great thanks.

Sharing/accessing files between laptop and imac

i want to make it so i have a "server" type thing where i can access files either from my laptop or imac but im at a loss figuring out how to do it and if i need an actual server hard drive thing.
any ideas?
is it possible to make a portion of my hard drive on my imac available to access files across my airport? maybe by just purchasing Mac OS X Server? whats the best way of achieving this? cheapest too!
could i get an external harddrive and act/use as if its the server?

There are quite a few options available to you with varying degrees of speed and integration.
Assuming that you take your PowerBook home
1) Buy a FireWire cable and boot your PowerBook into Target Disk Mode. This makes your PowerBook act like a hard disk on your desktop. This is by far the simplest and quickest solution.
2) Use networking/file sharing via either ethernet, Firewire or wireless.
3) Create a new user account on your desktop and set it to use your PowerBook home directory as its home directory. For this solution you're going to need to start your PowerBook in Target Disk Mode and be able to modify the new account under the root account to point it to your PowerBook's home directory. This is by far the most integrated solution as you will actually be using the same home directory on both computers though it is by far the most difficult to set up.
Assuming that you DON'T take your PowerBook home
1) Use a USB2 flash drive. My father does this for each of his clients that requires him to work at their offices (on PCs) and this works extremely well for him. This is a really cheap and simple solution but does mean that you can't be moving around huge amounts of data as you're limited by the small size of flash drives.
2) Buy yourself a portable FireWire hard drive to use on both computers. By the way, an iPod will work though won't be as quick due to its smaller and slower 1.8" drive.
3) Doing what you're doing now.

VirtualDisk on Windows Server 2012 R2 Storage Pool stuck in "Warning: In Service" state and all file transfers to and from is awfully slow

Greetings,
I'm having some trouble with my Windows Storage Pool and my VirtualDisk running on a Windows Server 2012 R2 installation. It consists of 8x Western Digital RE-4 2TB drives + 2x Western Digital Black Edition 2TB drives and have been configured in a single-disk
parity setup and the virtual disk is running fixed provisioning (max size) and is formatted with ReFS.
It's been running solid for months besides some awful write-speeds at times, it seems like the write performance running ReFS compared to NTFS is not that good.
I was recommended to add SSD's for journalling in order to boost write-performance. Sadly I seemed to screw up this part, you need to due this through PowerShell and it needs to be done before creating the virtualdisk. I managed to add my SSD to the Storage
Pool and then remove it.
This seem to have caused some awkward issues, I'm not quite sure of why as the virtualdisk is "fixed" so adding the SSD to the Storage Pool shouldn't really do anything, right? But after I did this my virtual disk have been stuck in "Warning:
In Service" and it seems to be stuck? It's been 4-5 days and it's still the same and the performance is currently horrible. Moving 40GB of data off the virtual disk took me about 20 hours or so. Launching files under 1mb of the virtual disk takes several
minutes etc.. It's pretty much useless.
The GUI is not providing any useful information about what's going on. What does "Warning: In Service" actually imply? How am I supposed to know how long this is supposed to take? Running Get-Virtualdisk in PowerShell does not provide any useful
information either. I did try to do a repair through the Server Manager GUI but it goes to about 21% within 2-3 hours but drops back down to 10%. I have had the repair running for days but it wont go past 21% without dropping back down again.
Running repair through PowerShell yields the same results, but if I detach the virtual disk and then try to repair through PowerShell (the GUI wont let me do repair on detached virtual disks) it will just run for a split second and then close.
After doing some "Googeling" I've seen people mentioning that the repair is not able to finish unless I have at least the same amount of free space in the Storage Pool as the largest drive in my Storage Pool is housing so I added a 4TB drive as
due to me running fixed provisioning I had used all the space in the pool but the repair is still not able to go past 21%.
As am running "fixed provisioning" I guess adding a extra drive to the pool doesn't do much difference as it's not available for the virtual disk? So I went ahead and deleted 3 TB of data on the virtual disk so now I've got about 4 TB free space
on the virtual disk so there should be plenty of room for Windows Server 2012 R2 to re-build the parity or whatever it's trying to do but it's still the same, the repair wont move past 21% and the virtual disk is still stuck in "Warning: In Service"
mode and the performance keeps being horrible so taking a backup will take forever at these speeds...
Am I missing something here? All the drives in the pool is working fine. I have verified using various bootable tools so why is this happening and what can I do to get the virtual disk running at full state again? Why doesn't the GUI prompt you with any
kind of usable information?
Best regards, Thomas Andre

Hi,
Please run chkdsk /f /r command on the virtual disk to have a try. In the meantime, run the following commands in PowerShell to share the output.
get-virtualdisk -friendlyname <name> | get-physicaldisk | fl
get-virtualdisk -friendlyname <name> |fl

Mandy

Sharing .itl file between Mac and Windows

How do I share an .itl file located on a NAS between a Windows machine and a Mac? I can do it with two Windows machines, but one I add a Mac, every time I switch platforms the library rebuilds. Onle one machine is accessing the itl file at a time, all the content is on the NAS, and I have 11.0.2.25 on the Mac and 11.0.2.26 on the Windows machine (can't get 11.0.2.25 on the Windows machine.

Right now, I have Verizon DSL that uses a Westell router. It has 4 ethernet ports on the back in addition to the DSL connections. I have a HP Pavilion with Windows XP in the basement, an iMac G3 in my room, and an intel iMac in our living room all connected to the router by ethernet cables. Each computer is able to access the other computer's files. On the intel iMac I have Microsoft Remote Desktop installed so that I can log into the HP in the basement and control it from the iMac. I haven't tried operating this network wirelessly, but I would imagine that it would be possible. One thing that you might want to check is the router's configuration. My router has settings that either allow or block wireless signals. To access my router's settings I type in 192.168.1.1 in Safari or Internet Explorer. Having all 3 computers on the internet at the same time does not slow the speed of the DSL very much.
I hope this information will help.

Home Sharing Issue Windows 7 x64 and Ipad 2 - Please Help!!!

Hi all,
Having problems getting remote sharing to work. I am able to pair the ipad with my itunes library so obviously they can see and talk to each other but when it searches for the home share it gives message "could not find".
not sure if its relevant but i also cant sync the ipad wirelessly.

Those that have issue with Apple TV will be here those that don't won't because they will be just enjoying themselves.
A few more things to try.
To force quit Remote on your iOS device, double-click the Home button (to view your recently used apps) and then touch and hold the Remote app icon until it begins to jiggle, then tap . Remote is added to recent apps again the next time you open it.
Do you have the latest iTunes 10.5.1?
Is iTunes > Preferences > Sharing tab > Share my library on my local network
and Share entire library selected.
Is your iTunes > Advanced > Home Sharing turn ON? (Try also to sign off and sign back on again)
Reboot your router (also update your router)
Is your router WMM On?
Remote uses TCP port 3689 and UDP port 5353 to communicate with your iTunes. To configure your firewall to add these ports.

Hello?
I bought a new/used open item macbook pro and tried to connect my iphone to it but it indicated I did not have the newest version of itunes. when i try to download it, at the end of the download, I receive an error message indicating the file is corrupt.

Hi Barbara,
I had a similar problem recently and using the "more like this" feature I discovered an answer. To a problem posed by Holo7, who like myself was a newbie on this platform, b noir proposed a solution to Holo7's problem that also worked with my problem. It involves downloading a version of MS Windows Instal Cleanup and using it to completely remove all traces of the old version.
If you look at my problem (follow OldGit66) and the link to Holo7's problem then you will find b noir's answer which I think may help you. I am new around here so you might want to wait for one of the higher status correspondents.

Flashing of MSI Z87-GD65 GAMING failed and dual bios not helping, not sure why?

Hi all
For the first time in 20 years Ive had a firmware flash fail it seems.
I have a MSI Z87-GD65 GAMING and updated the bios with the latest firmware via the "M-FLASH" utility within the systems bios.
All seemed to have gone well, it flashed to 100% rebooted and then just a blank screen and a sequence of keyboard light flashes.
After a minutes panic I thought not to worry, the motherboard has a dual bios. So I powered down and switched the bios switch to bios B hoping it would assist and the problem is identical.
Any tips anyone?

I just tried this along with removing power from the main board and it seems one of the two did it! thanks

Hyper V hosts with Cluster Shared Volume do not provide Shared VHDX ability

Hi there, i've configured a pair of Hyper V hosts (UCS B230 M2) with SAN-Boot and access to a Shared Fiber Channel LUN.
No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM, which prevents any VM based clustering from working (IE: Clustered
SQL server)
Here are the settings I have configured:
The LUN has been formatted with NTFS
The Hyper V hosts have been configured as a Windows Cluster with an IP address and the Fiber Channel LUN configured as a Cluster Shared Volume
I follows the guides below
Create a CSV
https://technet.microsoft.com/en-us/library/dn265980.aspx
Create a shared VHDX
https://technet.microsoft.com/en-us/library/dn282283.aspx
Further details:
Two HyperV server core hosts built
Both joined to AD
Both joined to a Windows failover cluster
One 2TB Fibre Channel LUN presented from an EMC VNX array to both hosts
LUN formatted as NTFS
LUN created as a Cluster Shared Volume
Cluster Shared Volume present on both HyperV hosts
VM created within the Cluster Shared Volume
VM Booted up and Windows 2012 has been installed
VM gracefully shut down
Through the HyperV Manager, going in to VM settings,create a SCSI adapter, create a new VHDX file inside the CSV, the “Advanced” option for the VHDX is not present, therefore the option to make the VHDX file shared is not available
I have followed all steps in the Microsft Technet pages to create a CSV and a VM with Shared VHDX
I’ve cleared all settings and restarted multiple times, but this option is not present

Hi Sir,
>>No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM
>>Yes we are using Hyper-V Server 2012 R2
As we know Hyper-v server 2012R2 is a free version without GUI , I'm afraid you are not using Win 8.1 or other windows server 2012R2 to manage that free version hyper-v server .
Shared vhdx is a new feature came with 2012R2 , if use previous windows to manage 2012R2 you will not see "advanced" option (The blue circle belongs 2012 , the red circle belongs to 2012R2 ):
