After the OSD comes back it seem to hang for around 2-4 minutes and then recovery seems to start (pgs in recovery_wait start to decrement). This is with ceph 0.61.7. I get a lot of slow request messages an hanging VMs. What i noticed today is that if i leave the OSD off as long as ceph starts to backfill - the recovery and "re" backfilling wents absolutely smooth without any issues and no slow request messages at all. Does anybody have an idea why? Greets, Stefan
