Hi,
I'm trying to add CEPH as Primary Storage, but my libvirt 0.10.2 (CentOS
6.5) does some complaints:
- internal error missing backend for pool type 8
Is it possible that the libvirt 0.10.2 (shipped with CentOS 6.5) was not
compiled with RBD support ?
Can't find how to check this...
I'm able
Thank you very much Wido,
any suggestion on compiling libvirt with support (I already found a way) or
perhaps use some prebuilt , that you would recommend ?

Hi,
I was wondering why would OSDs not start at the boot time, happens on 1
server (2 OSDs).
If i check with: chkconfig ceph --list, I can see that is should start,
that is, the MON on this server does really start but OSDs does not.
I can normally start them with: service ceph start osd.X
Hi.
I was wondering what would be correct way to migrate system VMs
(storage,console,VR) from local storage to CEPH.
I'm on CS 4.2.1 and will be soon updating to 4.3...
Is it enough to just change global setting system.vm.use.local.storage =
true, to FALSE, and then destroy system VMs
Thank you very much Wido, that's exatly what I was looking for.

So these 2 changes were more or a less done at the same time - rebalancing

Hi Sage,
can anyone validate, if there is still bug inside RPMs that does

We are instructed to first update/restart MONs, and after that OSD - but

Public network is clients-to-OSD traffic - and if you have NOT explicitely

Otherwise, you can define public and cluster(private) network - so OSD

Georgios,
no need to put ANYTHING if you don't plan to split client-to-OSD vs
OSD-OSD-replication on 2 different Network Cards/Networks - for pefromance
reasons.
if you have only 1 network - simply DONT configure networks at all inside
your CEPH.conf file...
if you have 2 x 1G cards in servers,
In that case - yes...put everything on 1 card - or if both cards are 1G (or
same speed for that matter...) - then you might want toblock all external
traffic except i.e. SSH, WEB, but allow ALL traffic between all CEPH
OSDs... so you can still use that network for public/client traffic - not
sure

Hi,
small update:
in 3 months - we lost 5 out of 6 Samsung 128Gb 850 PROs (just few days in
between of each SSD death) - cant believe it - NOT due to wearing out... I
really hope we got efective series from suplier...

Hi guys,
I have 1 SSD that hosted 6 OSD's Journals, that is dead, so 6 OSD down,
ceph rebalanced etc.
Now I have new SSD inside, and I will partition it etc - but would like to
know, how to proceed now, with the journal recreation for those 6 OSDs that
are down now.
Should I flush journal

Hi all,
when I run:
ceph-deploy osd create SERVER:sdi:/dev/sdb5
(sdi = previously ZAP-ed 4TB drive)

Is ceph-deploy going to create journal properly on sdb5 (something similar
to: ceph-osd -i $ID --mkjournal ), or do I need to do

not start if the journal was not created.

Guys,
I'm Igor's colleague, working a bit on CEPH, together with Igor.
This is production cluster, and we are becoming more desperate as the time
goes by.
Im not sure if this is appropriate place to seek commercial support, but
anyhow, I do it...
If anyone feels like and have some experience
This was related to the caching layer, which doesnt support snapshooting
per docs...for sake of closing the thread.

Make sure you test what ever you decide. We just learned this the hard way
with samsung 850 pro, which is total crap, more than you could imagine...

no so durable for writes, but we think more better to replace 1 ssd per 1
