No, you are not affected. Affected only clusters with mixed versions. k Sent from my iPhone

Hello,

thanks for your answer. If I understand you correctly then only if I upgrade from 14.2.11 to 14.2.(12|14) this could lead to problems. Does this mean that running 14.2.13 what I have currently installed is not affected?

The release note says:

* BlueStore: Fixes a bug in collection_list_legacy which makes pgs inconsistent during scrub when running mixed versions of osds, prior to 14.2.12 with newer.

This sounds to me like if I create a new OSD having ceph vers < 14.2.15 (like 14.2.13 in my case) installed and have OSDs created before 14.2.12 and then create a new one I could be affected by inconsitent pgs during scrubbing.

Have a nice day Rainer

Hello,

I am running a productive ceph cluster with Nautilus 14.2.13. All OSDs are bluestore and were created with a ceph version prior to 14.2.12.

What I would like to know is how urgent I should consider the collection_list_legacy bug since at the moment I am not going to add a brand new OSD to the system. However any time a disk could fail and so I would have to destroy the OSD with the failed disk and them with a new disk run ceph-volume to create a new bluestore OSD.

Would this scenario also lead to inconsistent pgs?

Thanks Rainer

Notable Changes --------------- * ceph-volume: Fixes lvm batch --auto, which breaks backward compatibility when using non rotational devices only (SSD and/or NVMe). * BlueStore: Fixes a bug in collection_list_legacy which makes pgs inconsistent during scrub when running mixed versions of osds, prior to 14.2.12 with newer. * MGR: progress module can now be turned on/off, using the commands: `ceph progress on` and `ceph progress off`.
