Mike we already have the async patch running. Yes it helps but only
helps
it
does not solve. It just hides the issue ...

I am also seeing recovery issues with 0.61.7. Here's the process:
- ceph osd set noout
- Reboot one of the nodes hosting OSDs
- VMs mounted from RBD volumes work properly
- I see the OSD's boot messages as they re-join the cluster
- Start seeing active+recovery_wait, peering, and active+recovering
- VMs mounted from RBD volumes become unresponsive.
- Recovery completes
- VMs mounted from RBD volumes regain responsiveness
- ceph osd unset noout
Would joshd's async patch for qemu help here, or is there something
else
going on?

Can you reproduce and attach the ceph.log from before you stop the
osd
until after you have started the osd and it has recovered?

Hi,
i still have recovery issues with cuttlefish. 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
