Hi all,
we have two small clusters (3 nodes each) called alpha and beta. One
node (alpha0/beta0) is on a remote site and only has monitor & manager.
The two other nodes (alpha/beta-1/2) have all 4 services and contain the
OSDs and are connected via an internal network. In short:
alpha0 ------ alpha1--alpha2
beta0 ------ beta1--beta2
Now, since a few weeks, I cannot run "ceph pg stat" or "ceph pg dump" or
anything the like on alpha0. It works flawlessly on all other nodes
including beta0. When I start such a command on alpha0, it just hangs
forever.
I wonder what could be the reason? Could it be some firewall issue? I
see nothing in the logs. Any ideas on how to debug this? I assume it's
not necessary to run this command on a node with OSDs, right, because it
works on beta0? I could swear it worked on alpha0 as well for many
months... I wonder what happened. Weird.
Thank you,
Ranjan
