Hi all, we recently upgrade from Jewel 10.2.10 to Luminous 12.2.7, now
we're trying to migrate the osd's to Bluestore following this document[0], however when I
mark the osd as out, I'm getting warnings similar to these ones 2018-09-20 09:32:46.079630 mon.dri-ceph01 [WRN] Health check
failed: 2 slow requests are blocked > 32 sec. Implicated osds
16,28 (REQUEST_SLOW) 2018-09-20 09:32:58.851142 mon.dri-ceph01 [WRN] Health check
update: 244944/40100780 objects misplaced (0.611%)
(OBJECT_MISPLACED) which prevent ceph start rebalancing and the vm's running on ceph start hanging and we have to mark the osd back in. I tried to reweight the osd to 0.90 in order to minimize the impact on the cluster but the warnings are the same. I tried to increased these settings to mds cache memory limit = 2147483648 but with no luck, same warnings. We also have cephfs for storing files from different projects(no directory fragmentation enabled). The problem here is that if one osd dies, all the services will
be blocked as ceph won't be able to start rebalancing. The cluster is - 3 mons - 3 mds(running on the same hosts as the mons). 2 mds active and
1 standby - 3 mgr(running on the same hosts as the mons) - 6 servers, 12 osd's each. - 1GB private network
Does anyone know how to fix or where the problem could be? Thanks a lot in advance. Jaime
