Nullfs sometimes fail to mount

[Unga]

Dear all
Sorry, I re-post as my previous post text does not show line breaks.

I mount GlusterFS at boot and use nullfs to remount part of GlusterFS to somewhere else, both via /etc/fstab. This remount “sometime” fails at boot.

I’m running 12.1-RELEASE (amd64 on intel i7) and glusterfs-3.11.1_6.

My /etc/fstab:
# Device Mountpoint FStype Options Dump Pass#
/dev/ada0p2 none swap sw 0 0
/dev/ada0p3 / ufs rw 1 1


# Mount GlusterFS volume
host1:/GFSVol /mnt/gluster/ fusefs rw,acl,transport=tcp,_netdev,backup-volfile-servers=host2:host3,mountprog=/usr/local/sbin/mount_glusterfs,late,failok,log-level=WARNING 0 0

# Mount home from GlusterFS
/mnt/gluster/Home      /home    nullfs    rw,late,failok  0  0


1. GlusterFS “always” mounts on /mnt/gluster/.
2.  The /mnt/gluster/Home “sometime” fails to mount on /home with following message on /var/log/messages:kernel: mount_nullfs: /mnt/gluster/Home: Socket is not connected

Am I missing any required mount option?
Thanks.
