Nullfs sometimes fail to mount on FreeBSD 12.1

[Unga]

Dear all
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 FreeBSD 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 volumehost1:/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.
