Hi, everyone!
I have 2+1 nodes CEPH cluster on PVE with configuration: 2 same nodes with 1 OSD and monitor on each (node-1 and node-2), 3rd node with a monitor only for quorum (i know it's necessarry to have minimum 3 node cluster, but it's no options to buy 3d server to deploy full-fledged 3-node cluster).
Settings of pool are: size - 2, min. size - 1.
It works pretty well when nodes-1,2 are up, but when node-1(2) with VM on it goes down, i tooks a lot of time (about 30 minutes) to start VM after it has been migrated to node-2(1). During this VM is frozen and it's impossible to view CEPH pools via GUI (page doesn't respond). But no problem with VM migration after one of nodes-1(2) is down, exept long starting time after it has been migrated.
I'm new with PVE and CEPH and don't know if the problem with cluster build (when only 1 node with OSD still working) or maybe i need to change something in configs.
Much thanks for any suggestions!
