I do not know about perf, but here is some info on what is safe and
general info.
- If you are not using VAAI then it will use older style RESERVE/RELEASE
commands only.
If you are using VAAI ATS, and doing active/active then you need
something, like the lock/sync talked about in the slides/hamme
were describing your
results? If so, were you running oracle or something like that? Just
wondering.

A few other notes:
- You'll certainly want QEMU 1.4.2 or later to get asynchronous io for RBD.

small writes before hitting the disks.

It is also useful to mention that you can set the noout flag when doing

I think my wording was a bit misleading in my last message. Instead of

I believe you need the command 'ceph osd create' prior to 'ceph-osd -i X

When I had similar trouble, it was btrfs file deletion, and I just had to wait
until it recovered. I promptly switched to xfs. Also, if you are using a

osd_journal | grep -v size

I use a process like:

I did not attempt to validate your crush map. If that command fails, I
would scrutinize your crushmap for validity/correctness.
Once you have the new crushmap injec
