Hi Sage,
i uploaded the query to http://yadi.sk/d/XoyLElnCDrc6Q

i removed, format and re-added osd.4
but after i saw this query, i found many "acting 4". and i think that

The rest (sda2 and sdb2) will go for the journals.

I did not get any answer to my basic cephx question last week, so let me

So, my issue is:

We did this with some servers 2 1/2 years ago with some Blade hardware: did not

Because of the latest librbd version, the image format has been changed from
“rbd:pool/image” to “pool/image”.
So you see the error msg “ could not open disk image”.

I think the version of Libvirt included with RHEL/CentOS supports RBD storage
(but not pools), so outside of compiling a newer version not sure there can be
anything else done aside from waiting for repo additions/newer versions of the
distro.

Hi James,
Thank you for this clarification. I am quite aware of that, which is why
the journals are on SAS disks in RAID0 (SSDs out of scope).
I still have trouble believing that fast-but-not-super-fast journals is
the main reason for the poor performances observed. Maybe I am mistaken?

Hi Dan,
Thank you for the advice and indications. We have the exact same
configuration, except I am only enabling "auth cluster", and I am using
"ceph.client.admin.keyring" instead of simply "keyring".

Hopefully a Ceph developer will be able to clarify how small writes are
journaled?
The write-through 'bug' seems to explain small-block performance I've
measured in various configurations (I find similar results to you).

If I understand correctly you have one sas disk as a journal for multiple OSDs.
If you do small synchronous writes it will become a IO bottleneck pretty
quickly:
