Fixed In Version: ceph-19.2.0-37.el9cp
Doc Type: Bug Fix
Doc Text:
.BlueStore no longer overwrites labels Previously, BlueFS would write over the location reserved for a label. As a result, the OSD would not start as expected. With this fix, the label location is marked as reserved and does not get overwritten. BlueStore now mounts and the OSD starts as expected.

Description Adam Kupczyk 2024-09-25 15:17:47 UTC 
Description of problem:

It could happen that BlueFS will take ownership over allocation unit reserved for BlueStore BlockDevice Label replica.
This is not data critical. There will be no data loss, but BlueStore will complain and refuse to start.
To force BlueStore mount with some labels corrupted, set "bluestore_bdev_label_require_all=false".
