Hi Stefan,
thanks for that hint. We use xfs on a dedicated RAID array for the MON stores. I'm not
sure if I have seen elections caused by trimming, I will keep an eye on it.
Best regards,

Just checking here, do you use xfs as monitor database filesystem? We
encountered monitor elections when monthly trim (discard unused blocks)
would run. Disabling the trims solved the issue for us. If you have
"discard" option enabled this might hurt you more often ...
