Hi, without more information I assume the affected PGs are from pools that rely on the host you’re trying to drain. How many hosts do you have, what’s the failure domain of the crush rules in use? Can you share the crush rule dump and ‚ceph osd pool ls detail‘? Lets assume that you have 3 hosts with replica 3 with failure domain host. Draining a host doesn’t allow any backfill because there aren’t any hosts available to backfill to without breaking the crush rule. Another reason could be mclock, but it usually showed very little backfill IO and not none in previous reports. So I’m guessing it’s the crush rule(s) and the number of hosts not suitable for recovery/backfill. Zitat von Maximilian Hill via ceph-users <ceph-users@ceph.io>:
Hello,
I'm running a cluster on Ceph squid 19.2.3. Currently a drain (ceph orch host drain) was started for a node.
Now I have misplaced objects and 605 PGs stuck in active+clean+remapped but no backfilling is active.
Can someone give me some advice? _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
