Hi, Mario!
Can you give more information about your cluster? Number of nodes,
OSDs per node, HDD models etc?
In general, you can use SSD as OSD journals (
http://irq0.org/articles/ceph/journal ), but it will give you
performance boost on relatively small bursty workloads. If you'll just
mix H
Hi all,
we had an ceph cluster with 7 OSD-nodes (Debian Jessie (because patched
tcmalloc) with ceph 0.94) which we expand with
one further node.
For this node we use puppet with Debian 7.8, because ceph 0.92.2 doesn't
install on Jessie (upgrade 0.94.1 work on the
other nodes but 0.94.2 looks not

Hey cephers,
Just a reminder that the Ceph Tech Talk on CephFS that was scheduled
for last month (and cancelled due to technical difficulties) has been
rescheduled for this month's talk. It will be happening next Thurs at
17:00 UTC (1p EST) on our Blue Jeans conferencing system. If you have
any qu

Hello all,
I'm trying to add a new data pool to CephFS, as we need some longer
term archival storage.
ceph mds add_data_pool archive
Error EINVAL: can't use pool 'archive' as it's an erasure-code pool
Here are the steps taken to create the pools for this new datapool:
ceph osd pool create arccac
(as per IRC) Yep, that's a bug alright. http://tracker.ceph.com/issues/12426
I expect we'll backport to hammer once fixed.

Hi Johannes,
Thanks for your reply.
I am naive for this, no idea how to make a configurations or where I can
starts? based on the 4 options mentioned.
Hope you can expound it further if possible.
Best regards,

Hi Mark
I've something like 600 write IOPs on EC pool and 800 write IOPs on replicated
3 pool with rados bench
With Radosgw I have 30/40 write IOPs with Cosbench (1 radosgw- the same with
2) and servers are sleeping :
- 0.005 core for radosgw process
- 0.01 core for osd process

Hello Mario,
in the end your workload defines which option(s) can be considered. They are
different trade offs between read/write performance and the price That depend
on your workload. E.g.
- distribution of reads/writes
- size of IO Requests (4k IO-Operations or 4MB..)
- „locality“ of the I
Hi Frederic,
When you have Ceph cluster with 1 node you don’t experienced network and
communication overhead due to distributed model
With 2 nodes and EC 4+1 you will have communication between 2 nodes but you
will keep internal communication (2 chunks on first node and 3 chunks on second
node)
Hi cephers,
I am using CephFS on AWS as persistent shared storage.
Last night, I upgraded to Hammer(v0.94.2) from Firefly, I cannot enable MDS
service.
Here is the log of MDS service:

Never mind, I know the root cause.

Hi Cephers.
I'm looking for solution to scrubbing process optimization. In our
environment this process make big impact on performance. For monitoring
disks we are using monitorix. If process running 'Disk I/O activity (R+W)'
shows 20-60 reads+writes per second. After disabling scrub and deep-scru
