Hello,
I've been doing a lot of reading and am looking at the following design
for a storage cluster based on Ceph. I will address all the likely
knee-jerk reactions and reasoning below, so hold your guns until you've
read it all. I also have a number of questions I've not yet found the
answer to
Hello,
I have 2 node ceph cluster, I just rebooted both of the host just for
testing that after rebooting the cluster remain work or not, and the result
was cluster unable to start.
here is ceph -s output
health HEALTH_WARN 704 pgs stale; 704 pgs stuck stale; mds cluster is
degraded; 1/1 in
I am currently trying to figure out how to debug pgs issues myself and
the debugging documentation I have found has not been that helpful. In
my case the underlying problem is probably ZFS which I am using for my
OSDs, but it would be nice to be able to recover what I can. My health

Karan,
This all looks great. I'd encourage you to submit some of this information
into the ceph docs, some of the openstack integration docs are getting a

Hey Guys,
Ross and I were discussing a few pages on Ceph.com that we thought
needed an update and I figured it might be a good idea to go through
and audit Ceph.com in general, just to get an idea of what we're up
against. I started a simple pad in case the Trello board is a bit too
daunting.

Hi Andrew,
That would be motivation enough for me to want to meet these two persons over a
beer or a diner :-) It gets more complicated to do that when there are more
than ten.
Cheers

This indicates you have multiple networks on the new mon host, but no
definition in your ceph.conf as to which network is public.
In your ceph.conf, add:
public network = 192.168.1.0/24
cluster network = 192.168.2.0/24
(Fix the subnet definitions for your environment)
Then, re-try your new mon
[kvm2][WARNIN] kvm2 is not defined in `mon initial members`
The above is why. When you run 'ceph-deploy new', pass it all the machines you
intend to use as mons, eg
'ceph-deploy new mon1 mon2 mon3'
Or alternately, you can modify the ceph.conf file in your bootstrap directory.
And the mon and t
So it sounds like there is only interest by two people. FYI, was looking
for sometime in mid Jan.

Are there any docs on how I can repair the inconsistent pgs? Or any thoughts on
the crash of OSD? Thanks!

Hi,
I have started stress testing the ZFS OSD backend on ceph 0.72.1 that I
built with ZFS support. Below is one of the issues I have been looking
at this morning. My main question is should I just open "new issues"
at http://tracker.ceph.com/ as I find these problems in my testing?

Thanks for the info everyone.

Hello,
new to Ceph, not new to replicated storage.
Simple test cluster with 2 identical nodes running Debian Jessie, thus ceph
0.48. And yes, I very much prefer a distro supported package.
Single mon and osd1 on node a, osd2 on node b.
1GbE direct interlink between the nodes, used exclusively for
