Repairing Inconsistent Placement Groups

Problem

Ceph is warning about inconsistent PGs.

Solution

Users are advised to refer to the upstream documentation Repairing Inconsistent PGs.

If users notice that deep-scrub is discovering inconsistent objects with a regular frequency, and if those errors coincide with SCSI Medium Errors on the underlying drives, it is recommended to switch on automatic repair of damaged objects detected during scrub:

# ceph config set osd osd_scrub_auto_repair true
