Using the latest lxd snap I’m seeing some oddities with Ceph snapshot handling as well as the inability to use Mimic’s balancer:
storage_version: ceph version 10.2.10 (5dc1e4c05cb68dbf62ae6fce3f0700e4654fdbbe)
trystan@sionis:~$ sudo ceph osd set-require-min-compat-client luminous
Error EPERM: cannot set require_min_compat_client to luminous: 4 connected client(s) look like jewel (missing 0x800000000000000); add --yes-i-really-mean-it to do it anyway
lxc snapshot container results in:
trystan@sionis:~$ lxc snapshot nginx
Error: invalid argument
There have been significant changes to RBD image handling in Luminous as well as Mimic and I’m curious if an option could be added to set a client version.
If I were to migrate to a ‘normal’ apt based LXD on 3.0 would I be able to utilize the Mimic client packages?
