Hi,
I'm looking for the best way to identify rbd images for libvirt locking
purposes on network disks, using librbd.
Could the block_name_prefix attribute be a good candidate ?
Any better suggestions ?
Thank you

Hi,
News. I tried activate disk without --dmcrypt and there is no problem. After
activate on sdb are two partitions (sdb2 for jounral and sdb1 for data).
In my opinion there is a bug with switch --dmcrypt and activating
journal on disk (partitions are created, but mounting done by ceph-disk fail)
Hello Joseph
This sounds like a solution , BTW how to set replication level to 1 , is there
any direct command or need to edit configuration file.
Many Thanks

Hi Karan,
There's info on http://ceph.com/docs/master/rados/operations/pools/
But primarily you need to check your replication levels: ceph osd dump
-o -|grep 'rep size'
Then alter the pools that are stuck unclean: ceph osd pool set
size/min_size #
If you're new to ceph it's probably a good
Apologies, that should have been: ceph osd dump | grep 'rep size'

Thanks Gregory,
One point that was a bit unclear in documentation is whether or not this
equation for PGs applies to a single pool, or the entirety of pools.
Meaning, if I calculate 3000 PGs, should each pool have 3000 PGs or should
all the pools ADD UP to 3000 PGs? Thanks!

I have clusters (IMAP service) with 2 members configured with Ubuntu +

Does Ceph work fine in clusters of two members?

It's not a hard value; you should adjust based on the size of your pools
(many of then are quite small when used with RGW, for instance). But in
general it is better to have more than fewer, and if you want to check you
can look at the sizes of each PG (ceph pg dump) and increase the counts for

Thanks again Gregory!
One more quick question. If I raise the amount of PGs for a pool, will this
REMOVE any data from the full OSD? Or will I have to take the OSD out and put
it back in to realize this benefit? Thanks!

After you increase the number of PGs, *and* increase the "pgp_num" to do
the rebalancing (this is all described in the docs; do a search), data will
move around and the overloaded OSD will have less stuff on it. If it's
actually marked as full, though, this becomes a bit trickier. Search the

This is probably a result of some difficulties that CRUSH has when using
pool sizes equal to the total number of buckets it can choose from. We made
some changes to the algorithm earlier this year to deal with it, but if
using a kernel client you need a very new one to be compatible so we
haven't e

Hrm, there's nothing too odd in those dumps. I asked around and it
sounds like the last time we saw this sort of strange memory use it
was a result of leveldb not being able to compact quickly enough. Joao
can probably help diagnose that faster than I can.

One thing to try is run the mon and then attach to it with perf and see
what it's doing. If CPU usage is high and leveldb is doing tons of
compaction work that could indicate that this is the same or a similar
problem to what we were seeing back around cuttlefish.

Hi Ceph,
Since there seems to be enough interest to move forward, I added a blueprint
for the creation of the User Committee so that we get a chance to reach an
agreement and nail down the last bits live in two weeks from now.

including multi-datacenter replication for the radosgw, improved
