cephfs-mirror as cephadm orchestrator service

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

we started a cephfs-mirror with

ceph orch apply cephfs-mirror

and added a peer cluster with bootstrapping:

ceph fs snapshot mirror peer_bootstrap import cephfs token…

The mirroring works, a newly create dsnapshot is mirrored to the other cluster.

But in the log of the cephfs-mirror container we still see error messages shortly after the bootstrapping:

unable to find a keyring on /etc/ceph/ceph.client.mirror_remote.keyring,/etc/ceph/ceph.keyring,/etc/ceph/keyring,/etc/ceph/keyring.bin,: (2) No such file or directory

Are these relevant at all? Why are they written to the log?

BTW: The documentation only shows how to start cephfs-mirror as systemd service with "systemctl enable" which is obviously not the way in a cephadm managed cluster: https://docs.ceph.com/en/pacific/cephfs/cephfs-mirroring/#starting-mirror-daemon
