LXC antlet access to external zpool and dataset on USB HD via mount --bind
Based on the below, you can bind a ZFS dataset to an LXC antlet.
I added an external HD with a 'backup' zpool and 2 datasets (backup/Images, backup/Data) and I would like to have a permanent bind of these datasets to the antlet. The below seems to work but breaks from time to time after a reboot and I need to re-bind them, any advice?
mount --bind /backup/Data /antlets/NAS/backup/Data
mount --bind /backup/Images /antlets/NAS/backup/Images
Thanks

Hi nadigo:
Can you let us know if the external zpool is still mounted after reboot?
Or is it just the bind that needs to be executed again?
After reboot, both the pool and zfs datasets for the external USB drives are mounted fine.
The bind mount didn't execute after reboot even after I added it to Antman fstab (see below)

From what I read, there used to be a bug in systemd when auto moving fstab binds mounts to systemd.
Added this to my systemd to see if this resolves the issue
** learned I need to keep the file name based on the directory structure (antlets-NAS-backup-Images.mount)
root@nadigo:systemd/system # cat antlets-NAS-backup-Images.mount
[Unit]
Description= nas bind
#Requires=
After=antman.service
[Mount]
What=/backup/Images
Where=/antlets/NAS/backup/Images
Options=bind
Type=none

Hi nadigo:
That's a great idea using systemd.
I was going to recommend using scheduling a crontab to execute the command, but systemd may be a better way to go.
