Hi,
server is running SLES 9 (latest Kernel for this is 2.6.5 with thousands
of SuSE patches...), clients are runing SLES 10 and SuSE 10.1.
We recently had some problems with the fibre channel bus, causing the
NFS-exported fs to disapear on the server. After restoring it and even
rebooting the NFS server, some clients are missing some subdirs. If
server hat /export/bla/blu, some clients see an empty /mnt/bla/ subdir,
others see the blu.
And I can't get rid of this. Restarting the nfs server, unexporting and
reexporting the server dirs, umount an remount on the clients, nothing
helps!
So when I call "umount /mnt/; mount server:/export/ /mnt", still "blu"
is missing. However, when I call "mount server:/export/bla /mnt/bla",
then the /mnt/bla/ directory is filled again. Unmounting it again,
and then unmounting and remount "/mnt" as a whole still gives an empty
bla subdir.
Only rebooting the client solves that issue.
Maybe some caching issue? Like the client remembers that /mnt/bla
was empty sometime and now keeps that info even after umounting and
remounting? Can I flush the info on the client somehow?
We can't upgrade the SLES9 server because any newer kernel crashes
the IBM xSeries (IBM has been working on that for some months, no
solution so far).
cu,
Frank
