we have suffered similar symptoms in the past with Kraken and Mimic and our
solution was to heavily constrain the rebalancing using these settings:
--------------------------------------------------------------------------------
[osd]
osd max backfills = 1
osd recovery max active = 1
osd recovery op priority = 2
--------------------------------------------------------------------------------
In case you haven't tried them, might be worth a shot.
You can even inject them into the running daemons using:
--------------------------------------------------------------------------------
ceph tell 'osd.*' injectargs '--osd-max-backfills X --osd-recovery-max-active Y'
--------------------------------------------------------------------------------
Best regards from the other side of the mountains,
Nico
