Grow LXD ZFS pool file (LXD snap package)
Raw
lxd-grow-zfs-pool-file.txt
According to: "Growing a loop backed ZFS pool" on https://lxd.readthedocs.io/en/latest/storage/
For LXD via Snap package:
- The default pool is located at /var/snap/lxd/common/lxd/disks/default.img
- and is named "default".
### To increase the pool size by 20 GiB do this:
>>> Stop all your containers! <<<
truncate -s +20G /var/snap/lxd/common/lxd/disks/default.img
zpool set autoexpand=on default
zpool online -e default /var/snap/lxd/common/lxd/disks/default.img
zpool set autoexpand=off default
... and turn your containers back on.
DONE! 🎉

Hi, any idea why i cannot find my default.img under the path /var/snap/lxd/common/lxd/disks/ ? By the way, I am using lxd via snap with zfs pool 'default' created. Everything works fine, but i want to grow my the disk size using this method.

Thanks for your advise. ;)

@HW-Siew,Hey a bit late to the party ik. But default here references the name of your storage pool. you can check the name of your storage pool and some info about them using lxc storage list and lxc storage info <poolName>
