On the NFS server, is the underlying filesystem a RAID or MD or other virtual device?
If so, you need to share it with an explicit fsid in /etc/exports, for example add fsid=1 to the options for the share. Otherwise it gets a new random fsid after reboot and the clients can't find the old filesystem (by fsid) any more. -- nfs client mount stales if accessed while nfs server is down/restarting https://bugs.launchpad.net/bugs/135586 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
