Source: ceph Version: 16.2.6+ds-8 Severity: critical Hi,
from https://docs.ceph.com/en/latest/releases/pacific/ V16.2.6 PACIFIC Danger DATE: 01 NOV 2021. DO NOT UPGRADE TO CEPH PACIFIC FROM AN OLDER VERSION. A recently-discovered bug (https://tracker.ceph.com/issues/53062) can cause data corruption. This bug occurs during OMAP format conversion for clusters that are updated to Pacific. New clusters are not affected by this bug. The trigger for this bug is BlueStore’s repair/quick-fix functionality. This bug can be triggered in two known ways: manually via the ceph-bluestore-tool, or automatically, by OSD if bluestore_fsck_quick_fix_on_mount is set to true. The fix for this bug is expected to be available in Ceph v16.2.7. DO NOT set bluestore_quick_fix_on_mount to true. If it is currently set to true in your configuration, immediately set it to false. DO NOT run ceph-bluestore-tool’s repair/quick-fix commands. Opening a bug to track it just in case...
