That may mean that it is already installed. Can you check if ceph is
installed and that you can move forward
with the rest of the process?

Well, as I understand it Seagate has their own home-rolled thing. I
believe there was some discussion at one point about using Ceph
together with their offering, but if I remember correctly Seagate
wanted to remove RADOS and just use Ceph clients, which didn't make a
lot of sense to us.

We did map it directly to the host, and it seems to work just fine. I
think this is a problem with how the container is accessing the rbd module.

Hi all,
We have a ceph cluster that being used as a backing store for several VMs
(windows and linux). We notice that when we reboot a node, the cluster enters a
degraded state (which is expected), but when it begins to recover, it starts
backfilling and it kills the performance of our VMs.
Hey folks - looking around, I see plenty (OK, some) on how to modify journal
size and location for older ceph, when ceph.conf was used (I think the switch
from ceph.conf to storing osd/journal config elsewhere happened with bobcat?).
I recently deployed a cluster with ceph-deploy on 0.67 and

Sounds like an issue with your apache config. How did you install your
apache? What distribution are you running on? Are you using it as
mpm-worker? Do you have non-default radosgw settings?

I'm not really an apache expert, but you could try looking at the apache

up. Also, just to be sure, both clients can download data
independently, just not together?

You can change some OSD tunables to lower the priority of backfills:
osd recovery max chunk: 8388608
osd recovery op priority: 2
In general a lower op priority means it will take longer for your
placement groups to go from degraded to active+clean, the idea is to
balance

Raghavendra,
You can follow the link Loic provided. If you are running on
CentOS/RHEL, make sure you install QEMU with RBD support. See
http://ceph.com/docs/master/install/qemu-rpm/
Make sure your QEMU and libvirt installs are working. Then do the
integration with OpenStack.

Maybe nothing to do with your issue, but I was having problems using librbd
with blktap, and ended up adding:
[client]
ms rwthread stack bytes = 8388608
to my config. This is a workaround, not a fix though (IMHO) as there is nothing
to indicate that librbd is running out of stack space,
The suspicious line in /var/log/debug (see the pastebin below) and that
'blkid' was the culprit keeping the device open looked like juicy clues:
