This is thanks to the following lines in /etc/init.d/nfsserver reload|force-reload) echo -n "Reload kernel based NFS server" # Unfortunately, there's no sane way of doing this: nfs4_unbind_mounts; nfs4_bind_mounts I tested this and it works as expected. If it still doesn't work for you please report which version of the nfs-kernel-server package you have installed, and run sh -x /etc/init.d/nfsserver reload > /tmp/log 2>&1 and attach the file "/tmp/log". -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

First being that some kernel thread seems to hold a reference on /srv/nfs4/home (nfsd itself?), so it can't be umounted, and causing it to be bound twice in the end. # rcnfsserver start Starting kernel based NFS server: idmapd mountd statd nfsd sm-notify done # cat /etc/exports /srv/nfs4 *(ro,no_subtree_check,fsid=0) /srv/nfs4/home *(ro,no_subtree_check,bind=/home) /home 127.0.0.2(ro,no_subtree_check) # df -Tah Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/home xfs 199G 175G 25G 88% /home /home none 199G 175G 25G 88% /srv/nfs4/home rpc_pipefs rpc_pipefs 0 0 0 - /var/lib/nfs/rpc_pipefs # rcnfsserver reload Reload kernel based NFS serverumount: /srv/nfs4/home: device is busy.

At best: do it consistently everywhere. umount -l $mountpoint is going to blow up easily. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

However I agree that using quotes here is best. I have submitted an update which added the quotes and the -l.
