Unless you have other tests in mind, I think there are no issues with the

Ilya,
I see. My server is has 24GB of ram + 3GB of swap. While running the tests,
I've noticed that the server had 14GB of ram shown as cached and only 2MB were
used from the swap. Not sure if this is helpful to your debugging.

Ideally I would like to have a setup with 2+ iscsi servers, so that I can
perform maintenance if necessary without shutting down the vms running on the
servers. I guess multipathing is what I need.
Also I will need to have more than one xenserver/vmware host servers, so the
iscsi LUNs will be
possible with iscsi?

ceph-osd processes are indeed using the library. I've upgraded to Jewel a few
days ago and see the same picture:
# time lsof |grep c
"ceph", MODE="660"
So, it looks as all /dev/sd** (including partition numbers) which has the model
attribute INTEL SSDSC2BA20 and changes the ownership. You might want to adjust
your model number for the ssd journals.

Hello ceph users,
I've recently upgraded my ceph cluster from Hammer to Jewel (10.2.1 and then
10.2.2). The cluster was running okay after the upgrade. I've decided to use
the optimal tunables for Jewel as the ceph status was complaining about the
straw version and my cluster settings were not

Hi Daniel,
Many thanks for your useful tests and your results.
How much IO wait do you have on your client vms? Has it significantly increased
or not?
Many thanks

Hello
We are planning to make changes to our IT infrastructure and as a result the
fqdn and IPs of the ceph cluster will change. Could someone suggest the best
way of dealing with this to make sure we have a minimal ceph downtime?
Many thanks

Gregory,
I've been given a tip by one of the ceph user list members on tuning values and
data migration and cluster IO. I had an issues twice already where my vms would
simply loose IO and crash while the cluster is being optimised for the new
tunables.
The recommendations were to upgrade the

Yip, no, I have not tried them, but I certainly will! Do I need a patched
libvirtd as well, or is this working out of the box?
Thanks

Yavor,
I would highly recommend taking a look at the quick install guide:
http://ceph.com/docs/next/start/quick-start/
As per the guide, you need to precreate the directories prior to starting ceph.
