Hi guys,
I try to bootstrap the monitor without setting the parameter
mon_initial_members or leaving it as none . But the mon still can be
created and run correctly. So as the osd.
Actually, I find that the command tool and osd hunts the mon based on
setting below, e.g.:
[mon.b]
host = ceph0

Dear Users,
whenever I run the command
ceph-deploy
with whatever option I got at the end this error message:

The command seems to work.
Can it be ignored?
Anyone else had this problem?

Hi Dan and Ashish,
Many thanks for the replies.
It is partly for the learning( and perhaps a production system in future) that
we are playing with ceph.
I guess, to start with, a simple set up of ,may be 4 vms, where one vm is admin

Learning about Ceph (configuration, operation wise) with VMs is fine.
Agreed. The getting started instructions walk you through creating most of a
cluster then adding once more node piecemeal, but this seems needlessly complex
for a beginner. I found the easiest way to get up and running was with three
VMs with one or two logical partitions for OSDs on each and

Hi cephers,
We have two pgs that are stuck in 'incomplete' state across two different
pools:
pg 2.525 is stuck inactive since forever, current state incomplete, last acting
[55,89]
pg 0.527 is stuck inactive since forever, current state incomplete, last acting
[55,89]
pg 0.527 is stuck
Thanks, Sage,
Can't wait to try it out and see if there are any improvements in the caching
pool tier.
Cheers

Hi Craig,
It's part of the way the CRUSH hashing works. Any change to the CRUSH map
causes the algorithm to change slightly.

That will fix itself over time. remapped just means that Ceph is moving
the data around. It's normal to see PGs in the remapped and/or backfilling
state after OSD restarts.
They should go down steadily over time. How long depends on how much data
is in the PGs, how fast your hardware is, how

I'm still pretty new at Ceph so take this with a grain of salt.
1. In our experience, we have tried SSD journals and bcache, we have had
more stability and performance by just using SSD journals. We have created
an SSD pool with the rest of the space and it did not perform much better
A small update on this, I rebooted all of the Ceph nodes and was able to then

Are these tests conducted using a local fs on RBD, or using CephFS?
If CephFS, do you have multiple clients mounting the FS, and what are
they doing? What client (kernel or ceph-fuse)?

It is CephFS mounted via ceph-fuse.
I am getting the same results not depending on how many other clients
are having this fs mounted and their activity.
Cluster is working on Debian Wheezy, kernel 3.2.0-4-amd64.

Yes, I know about rbd diff, but the motivation behind this was to be able to

I'm trying to change the value of mon_osd_down_out_subtree_limit from rack

Using injectargs it tells me that this isn't a runtime supported change
and changing it in the config file (global section) to either host or room
has no effect.
