Large files on automouted FS

[Pattabhi]

Hi Team,

I know there has been a lot of discussion over enabling large files on the FS in HP. but i have a different issue, All file systemes on my box are large file enabled, but when a user logs into his home directory (mounted via automount), he is not able to copy/generate a file more than 2 GB.

Is there something that i am missing???

# fsadm -F vxfs /
largefiles
# fsadm -F vxfs /usr
largefiles
# fsadm -F vxfs /opt
largefiles
# fsadm -F vxfs /data
largefiles
# fsadm -F vxfs /var
largefiles
#


I know for sure that the FS on which the home directories reside is large file enabled.

the error is below

[10] % pwd
/home/sadinar1/IS_171082641_benz_8.1.1.SP4_64/8.1.1.SP4/server/infa_shared/Backup
[11] % du -sk /data/Probe_bitek_kyb_20080527.rep

cp: /data/Probe_bitek_kyb_20080527.rep: File too large

Shalom,

NFS automount limitsations do not depend on the local box. They depend on the fileystem configuration on the server box. The command fsadm can not accurately check this on remote mounted filesystems.

This problem is either withe the version of NFS being used or limitations on the remote filesystem.

Well, the same thing just happened when I tried it.

Except when I went to the server, it said "nolargefiles". After I changed it and forced unmounted it, it still failed. :-(

Using google I found this thread:

You have to do exportfs -a again.

Thanks Mate,

Thanks for your time.

I have requeted my IT colleague to run the "exportfs -a" on the nfs server, one it is done i will re-try coping the file and see if it fixes the issue.


Fingers crossed,

I think this is your problem:

> # mount | grep home
> /home on auto_home
> ignore,indirect,rw,vers=2,dev=44000000
^^^^^^

If you're using NFSv2 the largest file supported is 2GB. Try using NFSv3.

This would only work if they just got through doing "fsadm -F vxfs -o largefiles" AND you weren't using vers=2. :-)
