With SNAP, LXD version 4.0.3 and lvm storage backend, thin pool, I would like to increase the size of the thin pool. Is it safe to use the normal “lvextend” command?
I just read the discussion here and this has me worried:
In other words, the only way LVM can at present be safely used with (snapped) LXD is if LVM is only used for LXD and nothing else on the host. Perhaps I am slow in this regard, but I would suggest that is a limitation unlikely to occur to many server admins unless it’s quite explicitly pointed out.
If a hypothetical server admin has a VG dedicated to (snapped) LXD which (I believe?) doesn’t currently raise any kind of warning during LXD setup, and that admin later decides to perform some maintenance on that VG (adding some more storage perhaps), are the potential consequences not sufficiently severe to warrant some sort of warning?
