Hi Jason, It was observed that the mirror status of image which was forcefully promoted (while working on failover scenario) is not getting updated for indefinite time. Is this expected ? -------------------------------- $ sudo rbd mirror image promote data/big --force Image promoted to primary $ date "+%T" 06:11:37 $ sudo rbd mirror image status data/big big: global_id: 9bfdf3e1-29d0-4c48-9bd1-e0ed3848d20f state: up+replaying description: replaying, master_position=[object_number=257, tag_tid=4, entry_tid=131609], mirror_position=[object_number=257, tag_tid=4, entry_tid=131609], entries_behind_master=0 last_update: 2018-10-26 05:47:10 $ sudo rbd info data/big rbd image 'big': size 10GiB in 2560 objects order 22 (4MiB objects) block_name_prefix: rbd_data.10806b8b4567 format: 2 features: layering, exclusive-lock, object-map, fast-diff, journaling flags: create_timestamp: Thu Oct 25 09:04:32 2018 journal: 10806b8b4567 mirroring state: enabled mirroring global id: 9bfdf3e1-29d0-4c48-9bd1-e0ed3848d20f mirroring primary: true -------------------------------- Is this expected ? Regards, Vasishta Shatsry QE, Ceph @Vasishta: do you have any additional steps to repeat this behavior? Was this cluster the primary cluster or one of the secondary clusters? Jason, I just put down primary and one of the secondary and promoted image from remaining one secondary. @Vasishta: "put down primary" as in shut down the cluster? That would result in the rbd-mirror daemon in-flight ops to that cluster getting hung, so at least that would explain why it wasn't getting updated. (In reply to Jason Dillaman from comment #11) > @Vasishta: "put down primary" as in shut down the cluster? Yes, I had shutdown the cluster. > That would result in the rbd-mirror daemon in-flight ops to that cluster getting hung, so at > least that would explain why it wasn't getting updated.
