Hello Atin,

> Check cluster.op-version, peer status, volume status output. If they are all fine you’re good.

Both `op-version` and `peer status` look fine:
# gluster volume get all cluster.max-op-version
Option                                  Value
------                                  -----
cluster.max-op-version                  31202

# gluster peer status
Number of Peers: 4

Hostname: glusterfs-server-004

However, `volume status` shows a missing snapshotd on the reinstalled
server (the 002 one).
We're not using snapshots so I guess this is fine too?
