Well as has been mentioned, Cache Pools isn't available yet however I'm

Hi All,
I left out my OS/kernel version, Ubuntu 12.04.4 LTS w/ Kernel
3.10.33-031033-generic (We upgrade our kernels to 3.10 due to Dell Drivers).
Here's an example of starting all the OSD's after a reboot.

Hi All,
There is a new release of ceph-deploy, the easy deployment tool for Ceph.
This release comes with two new features: the ability to add a new
monitor to an existing cluster
and a configuration file to manage custom repositories/mirrors.
As always, you can find all changes documented in th
Hi list,
Is there a way to get a list of all RADOSGW users?
We've been using the following so far, but it doesn't show users that
have been created but not done anything yet. I'd like a complete list,
including inactive users.
radosgw-admin usage show --show-log-entries=false --id radosgw.ga
How about this:
rados ls -p .users.uid
Your pool name may vary, but should contain the .users.uid extension.

When CephFS is mounted on a client and when client decides to go to sleep, MDS
segfaults. Has anyone seen this? Below is a part of MDS log. This happened
in emperor and recent 0.77 release. I am running Debian Wheezy with testing

Hi Hong,
May I know what has happened to your MDS once it crashed? Was it able to
recover from replay?
We also facing this issue and I am interested to know on how to reproduce it.
Thanks.

On client, I was no longer able to access the filesystem. It would hang.
Makes sense since MDS has crashed. I tried running 3 MDS demon on the same
machine. Two crashes and one appears to be hung up(?). ceph health says MDS is
in degraded state when that happened.
I was able to recover by r
Did you see any messages in dmesg saying ceph-mds respawnning or stuffs like

Hi Hong,
That's interesting, for Mr. Bazli and I, we ended with MDS stuck in (up:replay)
and a flapping ceph-mds daemon, but then again we are using version 0.72.2.
Having said so the triggering point seem similar to us as well, which is the
following line:

Luke,
Not sure what flapping ceph-mds daemon mean, but when I connected to MDS when
this happened there no longer was any process with ceph-mds when I ran one
daemon. When I ran three there were one left but wasn't doing much. I didn't
record the logs but behavior was very similar in 0.72 emp
Hello,
I plan to setup a Ceph cluster for a small size hosting company. The aim is
to have customers data (website and mail folders) in a distributed cluster.
Then to setup different servers like web, smtp, pop and imap, accessing the
the cluster data.
The goals are:
* Store all data replicated
