No, you are not affected. Affected only clusters with mixed versions.

 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

 This bug may be affect when you upgrade from 14.2.11 to 14.2.(12|14) with low speed (e.g.
one by one node). If you already upgrade from 14.2.11 you just jump over this bug.

 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

 This is the 15th backport release in the Nautilus series. This release
 fixes a ceph-volume regression introduced in v14.2.13 and includes few
 other fixes. We recommend users to update to this release.

 For a detailed release notes with links & changelog please refer to the
 official blog entry at https://ceph.io/releases/v14-2-15-nautilus-released

 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`.
