The following example from an /etc/fstab file causes the mount command to negotiate reasonable defaults for NFS behavior. The auto-mount itself now seems smarter then before; although I’m unsure exactly how, simply adding the root of the share is enough to see all the subvolumes in ZFS : tinky -rw,hard,intr,rsize=32768,wsize=32768,nfsvers=3\ /tinky 192.168.20.208:/tinky. Happy ZFS sharing 😉 // update An alternate way to mount an NFS share from another machine is to add a line to the /etc/fstab file.

A benefit to this is that it is not necessary to mount the zpool in /etc/fstab; the zfs daemon can import and mount zfs pools automatically. The daemon mounts the zfs pools reading the file /etc/zfs/zpool.cache. Mount /tank/info. Bind mount /tank/info/target to /srv/bind. I have the bind mount in /etc/fstab and it works fine, however when I reboot, both the bind mount *and* the ZFS mount both fail. The problem is that /etc/fstab gets processed first, which does the bind mount before ZFS has done anything.

Jun 11, 2020 · ZFS had a race in their systemd unit that we fixed last cycle (especially when mixing datasets from multiple pools).
