further investigation :- I have 4 partitions on 2 disks mounted in fstab, then these 4 partitions (ext4) are mounted with "bind" to /exports for eventual nfs4 export.
After reboot, some of these partitions are mounted, (according to mount) but are empty. If these /exports bind directories are umounted, then remounted with mount -a, then nfs-kernel-server restarted, there is no problem. It has been running without problem for some days now, when before it would show crash in logs every day, and freeze once per day or so. It is a pain to have to log into the file server and jigger around with mounts/exportfs manually, after every reboot. Could it be that some of the directories are exported before the "bind" mount is done, confusing the exportfs command? Is there some delay or change of dependencies in boot up that could delay the exportfs until all directories are correctly mounted? Is there some problem with nfs4 facls as noted with other launchpad bugs? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1353730 Title: nfs4 daemon crashes, eventually PC locks up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-lts-backport-oneiric/+bug/1353730/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
