> 24 active+clean+snaptrim
I see snaptrimming happening in your status output - do you know if
that was happening before restarting those OSDs? This is the mechanism
by which OSDs clean up deleted snapshots, and once all OSDs have
completed snaptrim for a given snapshot it should be removed
Thanks, we are storing a lot less stress.
0. I rebooted 30 OSDs on one machine and the queue was not reduced, but the
storage space was released in large amounts.
1. why did the reboot OSD release so much space?
Here are Ceph details..
ceph version 16.2.7
Hello,
Which version of Ceph are you using? Are all of your OSDs currently
up+in? If you're HEALTH_OK and all OSDs are up, snaptrim should work
through the removed_snaps_queue and clear it over time, but I have
seen cases where this seems to get stuck and restarting OSDs can help.
