Hallo, we are run a backup-server on opensolaris with zfs exported per nfs and on this server should also run glusterfs-server exported per nfs. Both ways work successful separately, but not parallel. errormessage: l2 # mount -t nfs nfsbackup:/pool_s5_3/backup/l2/ /mnt/backup mount.nfs: Unknown error 521 workaround: nfsbackup # /etc/init.d/glusterd stop It is possible to use both variants parallel?
