Konstantin, Thanks for explanation. But unfortunately, upgrading qemu is
nearly impossible in my case.
So is there something else I can do, or I have to agree with fact that
write IOPS had to be 8x smaller inside KVM rather than outside KVM? :|

Hello,
When I mount rbd image with -o queue_depth=1024 I can see much improvement,
generally on writes(random write improvement from 3k IOPS on standard
queue_depth to 24k IOPS on queue_depth=1024).
But is there any way to attach rbd disk to KVM instance with custom
queue_depth? I can't find any
ou. Even

Hello,
I wonder if it is any way to run `trimfs` on rbd image which is currently
used by the KVM process? (when I don't have access to VM)
I know that I can do this by qemu-guest-agent but not all VMs have it
installed.
I can't use rbdmap too, because most images don't have distributed
filesyste

Hello,
Few days ago I had very strange situation.
I had to turn off few OSDs for a while. So I've set flags:noout,
nobackfill, norecover and then turned off selected OSDs.
All was ok, but when I started these OSDs again all VMs went down due
to recovery process(even when recovery priority was ver
