Hi Venky,

“peer-bootstrap import” is working fine now. It was port 3300 blocked by firewall.
Thank you for your help.

Hi Venky,

Could this be the reason that the peer-bootstrap import is hanging?  how do I upgrade cephfs-mirror to Quincy?
root@fl31ca104ja0201:/# cephfs-mirror --version
ceph version 16.2.13 (5378749ba6be3a0868b51803968ee9cde4833a3e) pacific (stable)

Hi Venky,

I tried on another secondary Quincy cluster and it is the same problem. The peer_bootstrap mport  command hangs.

Hi Venky,



Thank you so much for the guidance. Attached is the mgr log.

[Also: Yesterday I had two cfs-mirror running one on fl31ca104ja0201 and fl31ca104ja0302. The cfs-mirror on fl31ca104ja0201 was stopped. When the  import token was run on fl31ca104ja0302, the cfs-mirror log was active. Just in case it is useful I have attached that log (cfsmirror-container.log) as well. ]



How can I list the token on the target cluster after running the create peer_bootstrap command?

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
