A repair is just a type of scrub and it is also limited by

If another scrub is occurring on any OSD in the PG it wont start.
do "ceph osd set noscrub" and "ceph osd set nodeep-scrub" wait for all
scrubs to stop (a few seconds probably)
Then issue the pg repair command again. It may start.
You also have pgs in backfilling state. Note that by default OSDs in
backfill or backfill_wait also wont perform scrubs.
You can modify this behavior with `ceph config set osd
osd_scrub_during_recovery
true`
I would suggest only setting that after the noscub flags are set and
the
only scrub you want to get processed is your manual repair.
Then rm the scrub_during_recovery config item before unsetting the
noscrub
flags.
Hi Simon
Just to add to Wes's answer, Cern have made a nice script that do the
steps Wes explained above
https://github.com/cernceph/ceph-scripts/blob/master/tools/scrubbing/autorepair.sh
that you might want to take a look at.
