[ale] SLES 11 SP4 df

[Lightner, Jeffrey]

"unloading"?

On RHEL not so long ago I had an issue with a client system due to the server being offline for an extended period.   I got the client going with the "-l" (lazy unmount) to umount when the "-f" wouldn't work.   You can see which nfs mounts your system thinks you have by doing "grep : /etc/mtab"

unloading the nfs client will normally clear the hang.

I have had that happen in my NFS environments on RHEL6 as well. I was only able to regain control of the system again after finding the off-line NFS mount. These are my current NFS mount options in my fstab:

 

rw,bg,rsize=65536,wsize=65536,hard,nfsvers=3,nointr,nosharecache,timeo=600,tcp

 

(yes, I am aware that ‘nointr’ is depreciated and ‘timeo=600’
is the default… not my idea to include them.)

Has anyone run across this situation?

It seems the df command in sles 11 sp4 stats all the filesystems before displaying anything. This means that when it gets stuck on a network file system it just stops doing anything. It's waiting for a reply from the file system that will never come. The user knows something is wrong but if it displayed results as it went along, they'd know which file system isn't responding.
