[KLUG Members] NFS problems viewing subdirectories

[John Pesce]

I noticed that same thing on a couple Suse Pro 9.2 clients.
Some sub-directories on NFS mounts would be there for a while and then
eventually not.
Rebooting the workstation fixed the problem, but then it might come
back.
Not sure if it is related, but eventually the local partitions on these
couple workstations became unreadable by Linux. FDisk said /dev/hda was
unreadable. Booting off an XP disk and running fdisk showed like 15
partitions. I had to delete them all, make a single NTFS partition and
format it, then go back to Linux and delete the NTFS and make new Linux
partitions.

Our 30+ other workstations seem ok.
