Hi ceph-users,
I recently deployed a ceph cluster with use of *ceph-deploy* utility, on
RHEL6.4, during the time, I came across a couple of issues / questions which I
would like to ask for your help.
1. ceph-deploy does not help to install dependencies (snappy leveldb gdisk

Hi all
Does gateway instances mean multi-process of a gateway user for a ceph cluster.
Though they were configured independently during the configure file,can they
configured with zones among different region?

Ø You can also create additional data pools and map directories to them, but
this probably isn't what you need (yet).
Is there a link to a web page where you can read how to map a directory to a
pool? (I googled ceph map directory to pool ... and got this post)

I see it's the undocumented ceph.dir.layout.pool
Something like:
setfattr -n ceph.dir.layout.pool -v mynewpool DIR
On an empty dir should work. I'd like one directory to be more heavily
mirrored so that a) objects are more likely to be on a less busy server b)
availability
Hello everyone,
I'm running a Cuttlefish cluster that hosts a lot of RBDs. I recently
removed a snapshot of a large one (rbd snap rm -- 12TB), and I noticed
that all of the clients had markedly decreased performance. Looking
at iostat on the OSD nodes had most disks pegged at 100% util.
I know

Travis,
RBD doesn't behave well when Ceph maintainance operations create spindle
contention (i.e. 100% util from iostat). More about that below.
Do you run XFS under your OSDs? If so, can you check for extent
fragmentation? Should be something like:
xfs_db -c frag -r
Hi Somnath,
With SSDs, you almost certainly are going to be running into bottlenecks
on the RGW side... Maybe even fastcgi or apache depending on the machine
and how things are configured. Unfortunately this is probably one of
the more complex performance optimization scenarios in the Ceph
Yes, I understand that..
I tried with thread pool size of 300 (default 100, I believe). I am in process
of running perf on radosgw as well as on osds for profiling.
BTW, let me know if any particular ceph component you want me to focus.
Thanks Regards
Somnath

From:
Likely on the radosgw side you are going to see the top consumers be
malloc/free/memcpy/memcmp. If you have kernel 3.9 or newer compiled
with libunwind, you might get better callgraphs in perf which could be
helpful.

Hi Mike,
Thanks for the info. I had seem some of the previous reports of
reduced performance during various recovery tasks (and certainly
experienced them) but you summarized them all quite nicely.
Yes, I'm running XFS on the OSDs. I checked fragmentation on a few of
my OSDs -- all came back

Hi,
I probably did something wrong setting up my cluster with 0.67.3. I
previously built a cluster with 0.61 and everything went well, even after
an upgrade to 0.67.3. Now I built a fresh 0.67.3 cluster and when I try to
mount CephFS:

Hello!
Does RADOS Gateway supports or integrates with OpenStack (Grizzly)
Authentication (Keystone PKI)?
Can RADOS Gateway use PKI tokens to conduct user token verification without
explicit calls to Keystone.
Thanks!

Thx Sage for help me understand Ceph much more deeply!
And recently i have another questions as follows,
1. As we know, Ceph -s is the summary of system's state, and is there any
tools to monitor the detail of data's flow when the Crush map is changed?
2. In my understanding, the mapping
