Hi *,
is there any correlation between multi-site clusters and inconsistent PGs?
One customer has two Octopus clusters (fresh install a few months ago)
which have been expanded recently with new disks. Before that they had
one single occurence of inconsistent PGs during a deep-scrub which
could be fixed.
Since the expansion they get them on a regular basis, something like
two times a day or so (I don't have access). The latest occurence was
reported as omap_digest mismatch which could be fixed with the pg
repair command.
There are no signs of failing disks or anything suspicious. And when
searching this list I noticed a couple of other threads (one in
example is [1]) with this problem, they all had rgw multi-site in
common. Is it just a conincidence? Does anyone have some insight or
more experience on this?
Thanks!
Eugen
