Subject: [ceph-users] Re: cephfs snapshot mirror peer_bootstrap import hung
Adding additional info:
The cluster A and B both have the same name: ceph and each has a single
filesystem with the same name cephfs. Is that the issue ?
Tried using peer_add command and it is hanging as well:
root@fl31ca104ja0201:/#ls /etc/ceph/
cr_ceph.conf client.mirror_remote.keying ceph.client.admin.keyring ceph.conf
(remote cluster)
root@cr21meg16ba0101:/etc/ceph# ls /etc/ceph

Hi
Could you please provide guidance on how to diagnose this issue:
In this case, there are two Ceph clusters: cluster A, 4 nodes and cluster B, 3
node, in different locations. Both are already running RGW multi-site, A is
master.
Cephfs snapshot mirroring is being configured on the clusters. Cluster A is
the primary, cluster B is the peer. Cephfs snapshot mirroring is being
configured. The bootstrap import step on the primary node hangs.
On the target cluster :
