The described problems were more like years ago than moons ago, however, 
there were some kernels a few moons ago that had NFS problems not due to 
reiserfs code just to keep things in a nice state of chaos for the 
users.....

We have noticed some serious issues with out linux based nfs server with
a reiser 3.6 partition on raid 1.  From the logs it appears like a nfs
locking issue.

Jan 19 11:25:29 liszt-06/liszt-06 kernel: vs-13075:
reiserfs_read_inode2: dead inode read from disk [30626 747337 0x0 SD].
This is likely to be race with knfsd. Ignore
Jan 19 11:29:51 liszt-06/liszt-06 kernel: vs-13075:
reiserfs_read_inode2: dead inode read from disk [30626 765040 0x0 SD].
This is likely to be race with knfsd. Ignore
Jan 19 11:31:47 liszt-06/liszt-06 kernel: vs-13075:
reiserfs_read_inode2: dead inode read from disk [30626 30908 0x0 SD].
This is likely to be race with knfsd. Ignore
Jan 19 12:14:55 liszt-06/liszt-06 kernel: vs-13075:
reiserfs_read_inode2: dead inode read from disk [30626 663906 0x0 SD].
This is likely to be race with knfsd. Ignore

The box has only been hosting mail queues for out postfix based cluster
and it has been running the 2.4.21 kernel when the above issue happened.

Now I understand from the kernel change logs that there have been many
changes to knfsd that could have been the cause of this issue, however I
cannot confirm that, so could I ask if anyone on this list knows if this
is a known issue and if it has been resolved in a more recent kernel and
if so which one.

Thanks in advance, kind regards - RL
