I'm experiancing similar issues with a RHEL 4 NFS server serving an 80 node RHEL 3 Beowulf cluster. With or without using the automounter I have a problem with home directories turning into stale NFS handles, back normal, then stale again. Altough they seem to be mostly always stale. The only pattern I've been able to find is that this affects directories where the directory structure has grown beyond the initial 4K inode. Example: drwx--x--x 36 jjneely jjneely 4096 May 26 14:48 jjneely drwx------ 4 foo foo 36864 Mar 11 16:11 foo My home directory (jjneely) has no problems. However, foo's home directory 9 times out of 10 is a stale NFS handle. With the automounter but not static mounts, I get the following error that I've been unable to track down: nfs_statfs64: statfs error = 2 If I can provide other information please let me know what to do. This LKML thread seems to sum up the problem nicely: http://www.ussg.iu.edu/hypermail/linux/kernel/0411.0/0364.html The patch we are testing for this is attached to bug 150759. For reference, you can find it directly at the url https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=114644 This patch is now in the upstream -mm kernel branch for testing. This fix was commited to 2.6 mainline on June 23. *** Bug 168986 has been marked as a duplicate of this bug. *** An advisory has been issued which should help the problem described in this bug report.
