Hi,
I try to start postgres cluster on VMs with second disk mounted from
ceph (rbd - kvm).
I started some writes (pgbench initialisation) on 8 VMs and VMs freez.
Ceph reports slow request on 1 osd. I restarted this osd to remove
slows and VMs hangs permanently.
Is this a normal situation afer cluster problems?
Definitely not. Is your cluster reporting as healthy (what's "ceph -s" say)? Can you get anything off your hung VMs (like dmesg output)?
