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".
