Are nfs mounts allowed in vfstab after a flash archive restore?

I am restoring a server using a flash archive. The vfstab on the original server contains an entry for an nfs mount. It looks like during the push of the archive to the new server, the vfstab gets saved to vfstab.orig and the nfs mount is removed from vfstab. So I added a finish script to add the nfs mount back to vfstab and now the server gets hung during S73nfs.client during reboot.
Are nfs mounts not allowed in vfstab after a flash archive restore?

One option is to secure the OBP with a password.
At the OK prompt, set the security-mode to "command" and then set a password. Careful not to loose this password. With this set the only option is to "boot" without supplying the firmware password.
Commands:
# halt
ok setenv security-mode = command
ok setent security-password <enterpasswd>
ok reset-all

NFS mount on boot failing after systemd upgrade

Hello,
after upgrading systemd (208-2 --> 208-3), nfs mount on boot will fail. Tested multiple times. After downgrading back to 208-2, all worked fine.
Output of journalctl --reverse:
Dependency failed for Remote File Systems.
Dependency failed for /mnt/demeter.
Dependency failed for File System Check on /192.168.20.70:/data.
Timed out waiting for device 192.168.20.70:-data.device.
/etc/fstab, the nfs line:

uname -a:

I'm using the latest packages (expect grub, it's the version before the current, because of huge ugrade problems, too).
Greetings,

Ah, big thanks. I thought the last column is the mount order, because it's called "pass". I changed it to zero, and now it works.

Security for flash archive restore with NFS

When Flash archive is restored by using NFS, user id and password is not required though they are asked in case of FTP used.
If NFS client host name is registered in NFS server, anyone can restore the backup file if only they know that host name with NFS server name and exported directory.
I found the kerberos selection during resotre process set up on Interactive install, which is on the following screen.

IPhone apps repeatedly asking to allow notifications, even after saying ok.

I have the 4s. Constantly apps are asking to allow notifications, even after allowing them. It seems to not remember my choices. I have restarted the phone and restored it twice. Same problem. Also, all of the newstand app subscriptions have to be restored constantly almost daily to download my issues. The Zinio app does the same thing. This is why I suspect it's not just an issue with individual apps, but a deeper issue within the phone or it's systems. It's kinda frustrating to redownload subscription content over and over again. I checked account settings and passwords, etc. nothing seems to fix it. Anyone else having these issues? I am on AT&T,64gb iPhone 4s. if anyone knows of a fix, please let me know.
Thanks for everyone's help.

If no change after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, more than likely your iPhone has a major hardware problem.
If your iPhone remains under warranty, you can call AppleCare or make an appointment at an Apple store if there is one nearby. You can make an appointment at an Apple store if there is one nearby regardless if your iPhone remains under warranty for a diagnostic check to be run on your iPhone to determine where the problem lies.

NAC and Allowing NFS Mounts

When a linux system boots, the 'root' processes typically attempts to mount network drives via NFS, prior to any user login on the system. In NAC, is it sufficient to add in the User Roles->Traffic Control->Unathenticated Role allowing TCP/UDP ports 111 & 2049 for the NFS mount process to work? We're using NAC v4.7.1
Thanks,
Doug

Doug,
If those two ports are what your NFS uses, then yes, opening them up in Unauthenticated role should be sufficient!

Removing NFS mounts after upgrade

In Tiger, I had set up a number of static NFS mounts to a Linux server using NetInfo. After upgrading to Leopard, these static links are no longer working, but the newly created automounts using Directory Utility work fine. I've been trying to remove the old entries using dscl without success. I have a number of entries in /Local/Default/Mounts, eg:
$ dscl localhost -read /Local/Default/Mounts/doobage:\/home\/michael
dsAttrTypeNative:type: nfs
AppleMetaNodeLocation: /Local/Default
GeneratedUID: B719E4FA-33F7-449A-AD63-0452515F0FF2
RecordName: doobage:/home/michael
RecordType: dsRecTypeStandard:Mounts
VFSLinkDir: /server/michael
I've tried deleting these using the dscl -delete command, eg:
$ sudo dscl localhost -delete /Local/Default/Mounts/doobage:\/home\/michael
Password:
delete: Invalid Path
<dscl_cmd> DS Error: -14009 (eDSUnknownNodeName)
I suspect that I'm simply using the wrong key name, however, there aren't any examples of deletion in the dscl man page. Can someone please point out where I'm going wrong?
Thanks,
-Michael

Some of my earliest photos are not showing on my phone after updating to iOS7. They can be seen in the app "over" which allows for art and lettering to be placed on a photo but I can not find an album for photos before 2012.

Some of my earliest photos are not showing on my phone5 after updating to iOS7. They can be seen in the app "over" which allows for art and lettering to be placed on a photo but I cannot find an album or year for photos before 2012 (in the photo app). The iphone says the photo content is there when I check in "about" under general in settings. So the pictures seem to be somewhere but I just can't access from from the photo app. Any suggestions. I also know that they were there before the iOS7 upgrade as I was looking for a pre 2012 picture last week and it we there.

Nfs mount point does not allow file creations via java.io.File

Folks,
I have mounted an nfs drive to iFS on a Solaris server:
mount -F nfs nfs://server:port/ifsfolder /unixfolder
I can mkdir and touch files no problem. They appear in iFS as I'd expect. However if I write to the nfs mount via a JVM using java.io.File encounter the following problems:
Only directories are created ? unless I include the user that started the JVM in the oinstall unix group with the oracle user because it's the oracle user that writes to iFS not the user that creating the files!
I'm trying to create several files in a single directory via java.io.File BUT only the first file is created. I've tried putting waits in the code to see if it a timing issue but this doesn't appear to be. Writing via java.io.File to either a native directory of a native nfs mountpoint works OK. ie. Junit test against native file system works but not against an iFS mount point. Curiously the same unit tests running on PC with a windows driving mapping to iFS work OK !! so why not via a unix NFS mapping ?
many thanks in advance.

Hi Diep,
have done as requested via Oracle TAR #3308936.995. As it happens the problem is resolved. The resolution has been not to create the file via java.io.File.createNewFile(); before adding content via an outputStream. if the File creation is left until the content is added as shown below the problem is resolved.
Another quick question is link creation via 'ln -fs' and 'ln -f' supported against and nfs mount point to iFS ? (at Operating System level, rather than adding a folder path relationship via the Java API).
many thanks in advance.

Permissions issue with NFS mounted MyCloud

FIrst off let me say I think this is a LInux issue and not a WDMyCloud issue, but I'm not sure, so here goes... I can rsync my stuff off the Linux systems on my LAN to back them up into a WDMyCloud share, no problem. But then I can't get at some stuff with limited file permissions, when I mount the WDMyCloud via NFS. Here's the problem... Let's s say my directory tree on the WDMyCloud looks like "/shares/Stuff/L1/L2/L3" where the permissions on "L3" look like this: drwx------+ 3 fred share 4096 Jul 1 01:03 L3 It's readable/writeable only by "fred". I want to preserve the permissions and ownerships on everything, so if I have to do a restore and "rsync" it back onto another machine they'll go back the way they were when I backed them up. I can see the contents of "L3" if I "ssh" into the MyCloud, *but* I *cannot* see the contents of "L3" if I try to look at it via the NFS mount - I get ls: L3: permission denied. If I change the permissions on it, e.g.drwxrwxrwx+ 3 fred share 4096 Jul 1 01:03 L3then I can see the contents of "L3" just fine. So it's just the fact that via the NFS mount the MyCloud NFS server (Or something?) won't give me access to it unless the permissions are open, even logged in as "root" on the machine where the MyCloud is NFS mounted. I tried creating "fred" as a user on the MyCloud *and* made sure the numerical UID and GIDs were the same on the Linux machine and the MyCloud - No dice. I haven't tried everything in the world yet (I haven't tried rebooting the MyCloud to see if some server hasn't picked up the changes to "/etc/passwd" or whatever ; there's something called "idmapd" that I guess I should look into... Etc.) But I thought maybe somebody here might have run into this or have a bright idea?

I had some problems, and I modified the /etc/exports file to meet a little more my needs This is the content of it: -------/nfs/jffs *(rw,sync,no_root_squash,no_subtree_check)/nfs *(rw,all_squash,sync,no_subtree_check,insecure,crossmnt,anonuid=999,anongid=1000)-------- The first line/share allows to change the permissisions and uid below them when you monted on your machineThe second one I maped the anonuid to the uid my user has on the wd (999) so when I mount a share on the machine everything is write with that used id If you modifes the /etc/exports file remeber to run after you edited the command "exportfs -a" to refresh the changes Hope this help with your problem

Cannot access external NFS mounts under Snow Leopard

I was previously running Leopard (10.5.x) and automounted an Ubuntu (9.04 Jaunty) Linux NFS mount from my iMac. I had set this up with Directory Utility and it was instantly functional and I never had any issues. After upgrading to Snow Leopard, I set up the same mount point on the same machine (using Disk Utility now), without changing any of the export settings, and Disk Utility stated that the external server had responded and appeared to be working correctly. However, when attempting to access the share, I get a 'Operation not permitted' error. I also cannot manually create the NFS mount using mount or mount_nfs. I get a similar error if I try to cd into /net/<remote-machine>/<share>. I can see the shared folder in /net/<remote-machine>, but I cannot access it (cd, ls, etc). I can see on the Linux machine that the iMac has mounted the share (showmount -a), so the problem appears to be solely in the permissions. But I have not changed any of the permissions on the remote machine, and even then, they are blown wide open (777) so I'm not sure what is causing the issue. I have tried everything as both a regular user, and as root. Any thoughts?
On the Linux NFS server:
% cat /etc/exports
/share 192.168.1.0/24(rw,sync,nosubtree_check,no_rootsquash)
% showmount -a
All mount points on <server>:
192.168.1.100:/share <-- <server> address
192.168.1.101:/share <-- iMac address
On the iMac:
% rpcinfo -t 192.168.1.100 nfs
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting
program 100003 version 4 ready and waiting
% mount
trigger on /net/<server>/share (autofs, automounted, nobrowse)
% mount -t nfs 192.168.1.100:/share /Volumes/share1
mount_nfs: /Volumes/share1: Operation not permitted

My guess is that the Linux server is refusing NFS requests coming from a non-reserved (<1024) source port. If that's the case, adding "insecure" to the Linux export options should get it working. (Note: requiring the use of reserved ports doesn't actually make things any more secure on most networks, so the name of the option is a bit misleading.)
If you were previously able to mount that same export from a Mac, you must have been specifying the "-o resvport" option and doing the mounts as root (via sudo or automount which happens to run as root). So that may be another fix.

Anyone else having problems with NFS mounts not showing up?

Since Lion, cannot see NFS shares anymore. Folder that had them is still threre but the share will not mount. Worked fine in 10.6.
nfs://192.168.1.234/volume1/video
/Volumes/DiskStation/video
resvport,nolocks,locallocks,intr,soft,wsize=32768,rsize=3276
Any ideas?
Thanks

Since the NFS points show up in the terminal app, go to the local mount directory (i.e. the mount location in the NFS Mounts using Disk Utility) and do the following:
First Create a Link file
sudo ln -s full_local_path link_path_name
sudo ln -s /Volumes/linux/projects/ linuxProjects
Next Create a new directory say in the Root of the Host Drive (i.e. Macintosh HDD)
sudo mkdir new_link_storage_directory
sudo mkdir /Volumes/Macintosh\ HDD/Links
Copy the Above Link file to the new directory
sudo mv link_path_name new_link_storage_directory
sudo mv linuxProjects /Volumes/Macintosh\ HDD/Links/
Then in Finder locate the NEW_LINK_STORAGE_DIRECTORY and then the link file should allow opening of these NFS point points.
Finally, after all links have been created and placed into the NEW..DIRECTORY, Place it into the left sidebar. Now it works just like before.

Cannot write to NFS mount with finder

hi folks
i have moved from a G4 cube running 10.4.9 to a new iMac running os x 10.5.7 (including upgrading from the old machine)
the NFS mounts i used to have with my G4 cube are not working properly; new mounts i've created aren't working properly either.
i can read/open file OK, but when i try to drag & drop files onto the NFS mount using the finder i get errors:
"You may need to enter the name and password for an administrator on this computer to change the item named test.jpg" [ stop ] [ continue ]
clicking "continue" i get:
"The item test.jpg contains one or more items you do not have permission to read. Do you want to copy the items you are allowed to read? [ stop ] [ continue ]
Choosing continue again results in the file appearing in the NFS directory, but with 0 size, and a time stamp of 1970.
if i try to copy the same file using the Terminal, it works fine - so it is not a simple NFS permissions problem - it is something particular to the Finder.
i am able to create a folder inside the NFS director by using the Finder.
i thought at first it might be related to the .DS_Store and similar files being written, so i tried turning off that behaviour:
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
but that hasn't fixed the problem
there are no obvious messages in any of the logs
any suggestions or pointers on how to fix this?

thanks for the reply
these articles appear to relate to sharing a mac filesystem via NFS: exporting the data.
i am referring to mounting a NFS filesystem from another server onto the mac (leopard) client
the mounting works fine: it's just the finder which isn't behaving. the finder worked in tiger; isn't in leopard.

Finder not refreshing file or folder names, in NFS mounts.

We are experiencing the an issues with NFS mounts, in both 10.7 and 10.8 machines. After mounting NFS shares, the file/folder names do not update in other MAC finder windows until it is unmounted and remounted on the MACs. This DOES NOT happen in our 10.6.8 and earlier machines.

Can you re-export an nfs mount as an nfs share

If so what is the downside?
I'm asking because we currently have an iscsi san and a recent upgrade
severely degraded iscsi connectivity. consequently can't mount my iscsi
volumes.

Depending on which Novell OS you are running.... this subform is for NetWare, but I suspect you are using OES Linux.
I've never tried creating a NCP share on OES for a remote NFS mount on the server. My first guess would be it is not allowed and also not a good practice. You could however, with this situation and if you are running an OES2 or OES 11 Linux server, try configuring an NFS mount on the OES server and then configuring the NCP share on that using remote manager on the server.
What I would recommend however to see if the iSCSI issue cannot be fixed or worked around.
Could you describe a bit more of the situation there/what happened and what is not working on that end?
