This seems like a bug. If I'm kicking off a repair manually it should take place immediately, and ignore flags such as max scrubs, or minimum scrub window.

I couldn't get one to kick off, until I temporarily increased the max_scrubs and lowered the scrub_min_interval on all 3 OSDs for that placement group. This ended up fixing the issue, so I'll leave this here in case somebody else runs into it.sudo ceph tell 'osd.208' injectargs '--osd_max_scrubs 3'sudo ceph tell 'osd.120' injectargs '--osd_max_scrubs 3'sudo ceph tell 'osd.235' injectargs '--osd_max_scrubs 3'sudo ceph tell 'osd.208' injectargs '--osd_scrub_min_interval 1.0'sudo ceph tell 'osd.120' injectargs '--osd_scrub_min_interval 1.0'sudo ceph tell 'osd.235' injectargs '--osd_scrub_min_interval 1.0'sudo ceph pg repair 75.302-Brett_______________________________________________On Thu, Oct 11, 2018 at 8:42 AM Maks Kowalik <maks_kowalik@xxxxxxxxx> wrote:Imho moving was not the best idea (a copying attempt would have told if the read error was the case here).Scrubs might don't want to start if there are many other scrubs ongoing.czw., 11 paź 2018 o 14:27 Brett Chancellor <bchancellor@xxxxxxxxxxxxxx> napisał(a):I moved the file.
