Ceph node crashes

[abarakat]

Hello, 4 node cluster running ceph 18.2.2. all 4 as monitors, all 4 setup for manager, all 4 have osd. Pool size 2 with min 2. After one of the nodes had 1 drive fail and 1 drive go offline it fully crashed. I am not using HA. Is it possible to move the VM's to other working nodes?

New to Ceph but my understanding is that it keeps copies on other node osd so theoratically I should be able to recover but how?

thanks

The VM configs are stored in the pmxcfs. If the disk images (and other resources) are available on the other nodes, you could manually move them to another node:

mv /etc/pve/nodes/{crashed node}/qemu-server/* /etc/pve/nodes/{target node}/qemu-server/
