Hi there rgw folks,
Just wondering if the server-side copy operation ties up the radosgw
host to actually proxy the data or if the copy is handled
transparently by rados and the backend OSDs?

Thanks, Brian. That helps a lot. I suspect that wasn't needed if the MON hosts

I'd like to decommission a node to reproduce the problem and post enough

Probably the crushmap would be of interest

Hello cephers,
I've been testing flashcache and enhanceio block device caching for the osds

If you're running a single client to drive these tests, that's your
bottleneck. Try running multiple clients and aggregating their numbers.

What I've found is the nicest way of handling this is to add all the
mons to your ceph.conf file. The QEMU client will use these if you
don't define any in the libvirt config.
Similarly, define a libvirt 'secret' and you can use that for auth, so
you only have one place to change it. My enti

Correct. I'd like to abstract the details of the rbd storage from the VM

Tuan,
I had a similar behaviour when I've connected the cache pool tier. I resolved
the issues by restarting all my osds. If your case is the same, try it and see
if it works. If not, I guess the guys here and on the ceph irc might be able to
help you.

Hi Dan,
Maybe I misunderstand what you are trying to do, but I think you are trying to

If so, it's relatively straightforward - here's an example from my setup:
