The other thing to note, too, is that it appears you're trying to decrease the
PG/PGP_num parameters, which is not supported. In order to decrease those
settings, you'll need to delete and recreate the pools. All new pools created
will use the settings defined in the ceph.conf file.

Hello,
This is my first real issue since running Ceph for several months. Here's the
situation:
I've been running an Emperor cluster for several months. All was good. I
decided to upgrade since I'm running Ubuntu 13.10 and 0.72.2. I decided to
first upgrade Ceph to 0.80.4, which was the la
tadata and
data pools to eliminate the HEALTH_WARN issue.

You can also use an RBD volume and place OCFS2 on it and share it that way, too.

I have a somewhat interesting scenario. I have an RBD of 17TB formatted using

The cluster is healthy, so I started playing with PG and PGP values. By the

I have a test cluster that is up and running. It consists of three mons, and

The bug tracker says this was resolved ten days ago. Also, I actually used

Round up your pg_num and pgp_num to the next power of 2, 2048.
Ceph will start moving data as soon as you implement the new 'size 3', so I
would increase the pg_num and pgp_num, first, then increase the size. It will
start creating the new PG's immediately. You can see all this going on using

will be completely functional.

Do you have all of the cluster IP's defined in the host file on each OSD
server? As I understand it, the mon's do not use a cluster network, only the
OSD servers.

The underlying file system on the RBD needs to be a clustered file system, like
OCFS2, GFS2, etc., and a cluster between the two, or more, iSCSI target servers
needs to be created to manage the clustered file system.

The formula was designed to be used on a per-pool basis. Having said that,
though, when looking at the number of PG's from a system-wide perspective, one
