Hi, Has anybody got problems using FS with NFS v4? We cannot write subjects if the SUBJECTS_DIR is in a NFS v4 system.
Many thanks, Gari

Hi FS experts, we have changed our file systems to NFS v4 and we found that FS cannot write to it (I mean, FS installed in an app server and subjects in the file system is not working). Last new I have is that FS in CentOS could read but not write and in Red Hat could not write or read.
Is it a known problem? Is it something going on with FS or the problem is in our end? (the rest of the programs are working fine: FSL, Matlab...)
Many thanks, Gari
How have you configured NFS? e.g. a simple check is to type # system-config-nfs
Then choose the filesystem and click "Properties". Make sure the bullet point labeled "Read/write" is chosen.

Gari,
At the NMR Center we use NFS v4 without problems with freesurfer. Is the SUBJECTS_DIR writable? Note that in the default freesurfer distribution, the freesurfer/subjects directory is not writable (contains sample and template subjects).

Thanks for the answers. I am not the sys admin, but I think I can answer both questions:
I assume the system is in read-write mode since the rest of the programs
(i.e. Matlab) are working.
The SUBJECT_DIR is in each personal space, I mean:
--- FS is installed in a Linux CentOS 5 machine, I have an account in that machine (and I can work normally if my SUBJECTS_DIR is in that machine) --- I have a personal drive space in the NFS 4, and I used to have my SUBJECTS_DIR in that drive, but after they upgraded it to NFS 4, it didn't work again.
We have a new cluster now, they are testing it, it has Red Hat installed,
with FS 5.2, and I've been told that it cannot write (same problem).
The strange thing is that other programs work fine with this setup.
Do you think the problem is in the file system config (it seems so) or in FS config to be able to work with NFS 4?
I have asked the sys admin for the output of the system-config-nfs, I don't have admin privileges to run it.
thanks again! Gari

Can you check that the UID and GID both match on the client and server sides? Is it the same user that is able to use other programs, yet unable to write via Freesurfer? Is your user an NIS account?
Can you output # ls -l $SUBJECTS_DIR
I assume that since you say other programs can write to the filesystem, it is mounted properly, but can you show what is in /etc/fstab? i.e. make sure you see "rw" instead of "ro".

Hello list, we found the problem, symbolic links:
/home/glerma/ is the home of the app server where fs is installed. /home/glerma/glerma/freesurfer/subjects was the SUBJECTS_DIR, but it has a sym link, since: glerma -> /bcbl/home/home_g-m/glerma so changing SUBJECTS_DIR to: /bcbl/home/home_g-m/glerma/freesurfer/subjects solved the problem.
Do you think this is a problem with fs resolving sym links? We haven't found any problem with matlab or fsl.
thanks again! Gari

I assume that since you say other programs can write to the filesystem, it is mounted properly, but can you show what is in /etc/fstab? i.e. make sure you see "rw" instead of "ro".

We have a new cluster now, they are testing it, it has Red Hat
installed, with FS 5.2, and I've been told that it cannot write (same problem).
The strange thing is that other programs work fine with this setup.
Do you think the problem is in the file system config (it seems so) or in FS config to be able to work with NFS 4?
I have asked the sys admin for the output of the system-config-nfs, I don't have admin privileges to run it.

Hi FS experts, we have changed our file systems to NFS v4 and we found that FS cannot write to it (I mean, FS installed in an app server and subjects in the file system is not working). Last new I have is that FS in CentOS could read but not write and in
Red

Is it a known problem? Is it something going on with FS or the

Gari,
Hi, your situation seems odd. Freesurfer does not require anything special in terms of a file system, or modify system settings of any sort, so I'm not sure what is happening in your situation. The recon-all script does set 'umask 002', which clears the write-bit for 'other' users. Perhaps this is conflicting with some special system setting? although i have never heard of a problem with umask so i'm grasping at straws here. sorry!
Nick

--- FS is installed in a Linux CentOS 5 machine, I have an account in
that
machine (and I can work normally if my SUBJECTS_DIR is in that machine) --- I have a personal drive space in the NFS 4, and I used to have my SUBJECTS_DIR in that drive, but after they upgraded it to NFS 4, it
didn't
work again.
We have a new cluster now, they are testing it, it has Red Hat installed,
with FS 5.2, and I've been told that it cannot write (same problem).
The strange thing is that other programs work fine with this setup.
Do you think the problem is in the file system config (it seems so) or in FS config to be able to work with NFS 4?
I have asked the sys admin for the output of the system-config-nfs, I don't have admin privileges to run it.
thanks again! Gari

Gari,
At the NMR Center we use NFS v4 without problems with freesurfer. Is the SUBJECTS_DIR writable? Note that in the default freesurfer distribution, the freesurfer/subjects directory is not writable (contains sample and template subjects).

Hi, Has anybody got problems using FS with NFS v4? We cannot write subjects if the SUBJECTS_DIR is in a NFS v4 system.
Many thanks, Gari

Hi FS experts, we have changed our file systems to NFS v4 and we found that FS cannot write to it (I mean, FS installed in an app server and subjects in the file system is not working). Last new I have is that FS in CentOS could read but not write and in
Red
Hat could not write or read.
Is it a known problem? Is it something going on with FS or the problem
is
in our end? (the rest of the programs are working fine: FSL,
Matlab...)
