Hi,No this must always be the same UUID. You can only specify one in cinder.conf.Btw nova does the attachment this is why it needs the uuid and secret.The first secret import generates an UUID, then always re-use the same one for all your compute node, do something like:secret ephemeral='no'
Hi,
there is a changlog about 0.61.4?
Thanks

There will be as soon as 0.61.4 is officially released. An announcement
to ceph-devel, ceph-users and the blog at ceph.com usually accompanies
the release.

Hi,
I am thinking how to make ceph with 2 pools - fast and slow.
Plan is to use SSDs and SATAs(or SAS) in the same hosts and define
pools that use fast and slow disks accordingly. Later it would be easy
to grow either pool by need.
I found example for CRUSH map that does similar thing by

Hi,
we run a 3 node cluster, every node runs a mon and 4 osds. 2 defined
pools, one with replication level 2, the second with replication level 3.
We now want to relocate one node from one datacenter to another, which
means a downtime of about 4 hours for that specific node, which
shouldn't hurt
We have resolved a number of issues that v0.61.x Cuttlefish users have
been hitting and have prepared another point release, v0.61.4. This
release fixes a rare data corruption during power cycle when using the XFS
file system, a few monitor sync problems, several issues with ceph-disk
and

Howdy!

I am curious about the quorum process because I seem to get conflicting
information from experts. Those that I report to need a clear answer from
me which I am currently unable to give.
Ceph needs an odd number of monitors in any given cluster

Quorum means you need at least %51 participating be it people following
parliamentary procedures or mons in ceph. With one dead and two up you have
%66 participating or enough to have a quorum. An even number doesn't get you
any additional safety but does give you one more thing than can fail
I'm still using Fedora 17 on some machines that use Ceph, and it seems that
the official Ceph RPM repository for Fedora 17
(http://eu.ceph.com/rpm-cuttlefish/fc17/x86_64/) hasn't seen any new releases
since 0.61.2.
Are you discontinuing RPMs for Fedora 17?

Is way to exclusive map rbd?
For example - I map on host A, then I try map it on host B. I want fail
map on host B while it mapped to host A.
I read about lock command, I want atomic lock and mount rbd for one host
and auto unlock it when host A fail.

Anyone saw the same issue as below?
We are trying to test the multi backend feature with two RBD pools on Grizzly
release. At this point, it seems that rbd.py does not take separate cephx users
for the two RBD pools for authentication as it defaults to the single ID
defined in
Thanks! Rethinking same first example I think it is doable even like
shown there. Nothing prevents mapping osds to host-like entities
whatever they are called.

It is possible to create all of the pools manually before starting
radosgw. That allows control of the pg_num used. The pools are:
.rgw, .rgw.control, .rgw.gc, .log, .intent-log, .usage, .users,
.users.email, .users.swift, .users.uid

Hi List,
The default journal size is 1G, which I think is too small for my Gb network. I
want to extend all the journal partitions to 2 or 4G. How can I do that? The
osds were all created by commands like ceph-deploy osd create
ceph-node0:/dev/sdb. The journal partition is on the same disk
Hi all
I'm building a small ceph cluster with 3 nodes (my first ceph cluster).
Each Node with one System Disk, one Journal SSD Disk and one SATA OSD
Disk.
My question is now should I use Desktop or Enterprise SATA Drives?
Enterprise Drives have a higher MTBF but the Firmware is actually

Surprisingly we encountered ceph-mon core dumped today. It was not peak
load time and system was technically in good state.
