I do not have a test Ceph cluster to test this with, so wondering if anybody got some info. I have always used 2 ceph pools for KVM and LXC disk images. On LXC Ceph pool I had KRBD enabled while the pool for KVM disk images had KRBD disabled. My question is, can I enable KRBD on the non-KRDB pool which has live VM disk images and move LXC disk images onto it or will enabling KRBD on it will mess up data? Basically trying to eliminate unnecessary Ceph pools to reduce the number of PGs. How are you Ceph users using pools?
