ncdu on several million inodes is *slow*, this is going to take a while...

I have moved /srv/storage/space/annex on a dedicated zfs volume.

The thing I am note sure about is the order of operations at boot time, between mounts and nfs exports.
We need to ensure that /srv/storage/space is mounter before zfs start, then and only the nfs exports should occur.

What needs to be checked on next reboot is:

  • will /srv/storage/space be mounted before zfs is started (probably not according to the content of /lib/systemd/system/zfs-mount.service)
  • will nfs exports take place after zfs volumes are mounted (probably ok)

Also we may prefer to use zfs-share.service to declare nfs exports for the annex (and any other zfs-backed volumes that needs to be exported via nfs) instead of managing this 'by hand' in /etc/expots

See the sharenfs property of a zfs volume in 'man zfs'.
