Hi all, I am planning to install a ceph cluster and I have 3 nodes with 2
nic for each one.

cluster network.

mount ceph file system or to access rbd
Hi all,
I am planning to install a ceph cluster for testing but, in the future, I'd
like to use
it in production for kvm virtualization .
I'd like to use rbd and not ceph file system.
Which is the best linux operating system you suggest for ceph nodes and

Dear experts,
Recently, a disk for one of our OSDs was failure and caused osd down,

Hi ,
As we all know , we need to create keyring in ceph-storage-cluster . So
the radosgw can use them to communicate with ceph-storage-cluster.
My question is : how the radosgw can get the keyring information???
I guess there will be the same /etc/ceph/ceph.conf and

Hi,
I think you can check this wiki:

currently, only ubuntu 12.04 is deeply tested with inktank (but I think it'll
be rhel7 soon ;)
the wiki don't have been updated yet for firefly.

I've got 16 nodes cluster ssd only. Each node is 6x600GB, 10Gbit uplink.
We're using Intel 320 series. Cluster is running now half year as production
and no problems with ssds.

space).

Don't use nginx. The current version buffers all the uploads to the
local disk, which causes all sorts of problems with radosgw (timeouts,
clock skew errors, etc). Use tengine instead (or apache). I sent the
mailing list some info on tengine a couple weeks ago.
On 5/29/2014 6:11 AM,
From the docs, you need this setting in ceph.conf (if you're using
nginx/tengine):
rgw print continue = false
This will fix the 100-continue issues.

Yes, I read this. I responded with new question.

I can't find solution.
