Hello,
I am just getting started with LXD. I have an existing zfs pool,
and want to use a ZFS dataset on that pool to store my containers on.
I ran the command lxc storage create pool1 zfs source=fast/containers,
and it appeared to create it, however, I do not see it in the /fast
directory nor does zpool status list this.
It's possible that I don't understand how this works however. I do see
it created if I run the command lxc storage list, it does indeed show up:
| pool1 | | zfs | fast/containers | 0
I created a container for testing thinking it would show up, but no go
on that either.
Would like to understand how this is implemented and what I should expect?
Hi,
I'm also new to zfs and lxd so my help is limited.
Did you mount your zfs dataset anywhere? My ubuntu system is like
/var
/lib
/lxd
/containers
...
/storage-pools
/lxd <-- my lxc pool name; zfs dataset name; mountpoint
/containers
...
/snapshots
For this to work you *must* mount your dataset before you create any
containers. If you already have containers you won't be able to mount
over the top of them. zfs wants an empty mountpoint AFAIK
I mounted one level above /containers so I could get all the images,
snapshots, deleted, and containers, etc in one place and allow for
moving them as a "set".
Note that /lxd was put there by the lxc storage command. Your pool1 is
probably there, too.
