Hi Ilya,
I found that problem was while enabling mirror on the pool, the
site-name wasn't specified correctly. I had to explicitly defined site
name while enabling mirror on the pool and now all works fine.
Thank you!

Hi,
I'm setting up RBD mirror between two Ceph clusters and have an issue to
set up rx-tx direction on primary site.
Issuing the command
rbd mirror pool peer bootstrap import --direction rx-tx --site-name
primary rbd token
Hi Denis,
Normally, the token is created on the primary cluster and imported on
the secondary cluster. Judging by --site-name primary here, you seem
to be doing it the other way around?
I'm expecting the bi-directional mirror for the pool rbd. But I'm
getting tx-only:
Mode: pool
Site Name: primary
Peer Sites:
UUID: df53d6f6-bd5e-44c1-adbe-90c170a90b27
Name: secondary
Mirror UUID: af8cc295-0574-4add-98aa-01018082e5e1
Direction: tx-only
Both clusters can talk to each other and I can issue the ceph commands
between both. On secondary cluster direction is rx-tx and this happens
on primary only.
Are rbd-mirror daemons running?
I would suggest starting from scratch and if it still doesn't work,
pasting all steps here. To start from scratch, remove the peers on
both sides:
Cluster A:
$ rbd mirror pool peer remove rbd df53d6f6-bd5e-44c1-adbe-90c170a90b27
$ rbd mirror pool disable rbd
Cluster B:
$ rbd mirror pool peer remove rbd <see rbd mirror pool info on cluster B>
$ rbd mirror pool disable rbd
And set up bidirectional mirroring as follows:
Cluster A:
$ rbd mirror pool enable --site-name cluster-a rbd pool
$ rbd mirror pool peer bootstrap create rbd > token-file
Cluster B:
$ rbd mirror pool peer bootstrap import --site-name cluster-b rbd token-file
Thanks,
Ilya
