Hi ,
I am facing new problem in NFS lock krecovery
on sles9 sp1 beta2 release.
This problem was not there in slses9 rc5
release.
PROBLEM:
NFS stale handle error if client tries to reclaim lock
for filesystem exported with subtree_check option
DESCRIPTION:
1.I exported whole filesystem to client using rw ,
no_root_squash option.By default subtree_check
option is enabled.
2.When server restarts and client tries to
reclaim lock , it gets NFS_STALE_FH error.
3.If server exports filesystem system with
additional option no_subtree_check client then
faces no problems.
4.Problem is in function nfs_acceptable
function(nfsfh.c) or functions calling
nfs_acceptable function.This function somehow
returns 0 which means invalid handle.
5.Message in /var/log/message file
"nfs_acceptable failed at ...."
HOW TO SETUP:
1.Set up two systems with a shared disk
2.start nfs server on first system and export
filesystem present on shared disk to client
with rw,no_root_squash option.
3.Let client reclaim lock .
4.Stop nfs server on first system before client
releases lock.
5.Now , start nfs server on second system.
6.Client gets NFS_STALE_FH error when it tries
to reclaim lock
If i am missing anything or somebody else
is facing same problem please let me know.
thanks,
kiran

That is a known server bug, and is not just limited to locks. Neil
committed the following fix to Bitkeeper not too long ago.
