After reboot, clients started to see partial directories, or cannot open/create files in their cwd, with the "stale NFS file handle" message. Using no_subtree_check option in /etc/exports helped, as well as going back to 2.4+XFS. It is probably not XFS related, because I had the same problem on an older HW of this server (which had an ext3 volumes on software RAID) and some 2.6.0-pre kernel. At that time I did not know that I had to try no_subtree_check, so I don't know whether this would have fixed the problem on the older HW. I went back to 2.4 then. The machine serves the home directories via NFS and Samba. I have home directories for ~2200 users there, each one with its own /etc/exports entry[1]. NFS clients are various Linux, Solaris and IRIX workstations and servers. Is it possible to use subtree_check in NFS in 2.6? Thanks, -Yenya [1] For another unrelated user-space problem with such a big /etc/exports, see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=76643 -- | Jan "Yenya" Kasprzak | | GPG: ID 1024/D3498839 Fingerprint 0D99A7FB206605D7 8B35FCDE05B18A5E | | http://www.fi.muni.cz/~kas/ Czech Linux Homepage: http://www.linux.cz/ | | I actually have a lot of admiration and respect for the PATA knowledge | | embedded in drivers/ide.
