Title:
nfsd stops running shortly after clients connect
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Ubuntu 14.04.1 server fully updated. nfs-kernel-server stops working,
hanging clients who have mounted shares. Sudo service nfs-kernel-
server restart will appear to work, but sudo service nfs-kernel-server
status will show nfsd not running. It can't be restarted successfully
unless rebooted. nfsd will stay up until clients mount and use the
share. dmesg shows tainted kernel. The only way to stop this behavior
was to edit /etc/default/nfs-kernel-server RPCMOUNTDOPTS="--manage-
gids --no-nfs-version 4" and edit fstab on the clients to use vers=3
as a mount option.
Testing now to see whether all that's required to trigger nfs-kernel-
server crash is a client w/out vers=3 mount option.
