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.

Going by your description, I'm guessing this is the command that hangs? If that's the case, set `debug_mgr=20`, repeat the token import step and share the ceph-mgr log. Also note that you can check the mirror daemon status as detailed in https://docs.ceph.com/en/latest/dev/cephfs-mirroring/#mirror-daemon-status
