Do you have a custom value for osd_snap_trim_sleep ? On Wed, Apr 8, 2020 at 2:03 PM Jack <ceph@jack.fr.eu.org> wrote:
I put the nosnaptrim during upgrade because I saw high CPU usage and though it was somehow related to the upgrade process However, all my daemon are now running Octopus, and the issue is still here, so I was wrong

Hello,
I've a issue, since my Nautilus -> Octopus upgrade
My cluster has many rbd images (~3k or something) Each of them has ~30 snapshots Each day, I create and remove a least a snapshot per image
Since Octopus, when I remove the "nosnaptrim" flags, each OSDs uses 100% of its CPU time
Why do you have the 'nosnaptrim' flag set? I'm missing that piece of information.
The whole cluster collapses: OSDs no longer see each others, most of them are seens as down .. I do not see any progress being made : it does not appear the problem will solve by itself
What can I do ?
