I'm having problems with AUFS I'd appreciate a hand with. Relevant mounts:
/nfsshare - shared nfs which is mounted at /mnt /mnt - is an nfs mount /tmpfs - a tmpfs mountpoint /aufs - the union of the two I've tried with all different udba settings. Any cached inodes on the /aufs mount stay permanently. If I ls /aufs/test and it's not there, then I go touch /nfsshare/test or /mnt/test the are still unavailable in /aufs If I rm the file after forcing linux to flush with "echo 3 > /proc/sys/vm/drop_caches", AUFS can see the test file now, only if I rm it either from /mnt or /nfsshare I then continually get: ls: cannot access test: Stale NFS file handle It never clears until I manually force clearing the inode cache. I'm currently battling this problem with the /etc/passwd file in a library where 30 workstations use AUFS to overlay tmps on a / that's mounted ro via NFS. Is there any way to perhaps make it so certain single files never get cached? if I could at least get /etc/passwd and /etc/group to never cache or bypass AUFS on those I'd be happier. Thanks. I've tried on Kubuntu 9.10 and the upcoming 10.04. My current info is: r...@gadsden:~/libuntu# modinfo aufs filename: /lib/modules/2.6.32-15-generic-pae/kernel/ubuntu/aufs/aufs.ko version: 2-standalone.tree-20091207 I ran this same type of setup 4 years ago with unionfs and didn't have this problem, but for all I know something has changed in NFS that would make it happen with unionfs now too. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
