Hello,
I tried to upgrade to 0.56.1 this morning as it could help with
recovery. No luck so far...
What's wrong with your primary OSD?
I don't know what's really wrong. The disk seems fine.
In general they shouldn't really be crashing that frequently and if you've got
a new bug we'd
Hi,
We recently experienced issue with the backplane of our server, resulting in
loosing half of our osd.
During that period the rados gateway failed initializing (timeout).
We found that the gateway was hanging in the init_watch function.
We recreate our OSDs and we still have this issue, but

Everything seems to be there but I don't know the order of the rbd

Yes, that is doable. The problem only is that RBD is sparse. So you'd

Yes, that is doable.
Notify and gc objects where unfound, we marked them as lost and now the rados
start.
But this means that if some notify object are not fully available, the
radosgateway stop responding.

I'm confused. Isn't the HeartbeatMap all about local thread

overloaded.

I have been testing ceph for a little over a month now. Our design goal is to
have 3 datacenters in different buildings all tied together over 10GbE.
Currently there are 10 servers each serving 1 osd in 2 of the datacenters. In
the third is one large server with 16 SAS disks serving 8 osds.
We lost data in notify and gc. What bother me is that the rados gateway can
start if we desactivate the cache.
I think the availability of the cache objects shouldn't take down the rados
gateway. The option should be more a I want the cache if available.

I tried increasing the number of metadata replicas from 2 to 3 on my

Afterwards it appears that all the metadata placement groups switch to
a degraded state and doesn't seem to be attempting to recover:

What are your CRUSH rules? Depending on how you set this cluster up,
it might not be placing more than one replica in a single host, and
you've only got two hosts so it couldn't satisfy your request for 3
copies.

That would make sense. Here's what the metadata rule looks like:
rule metadata {
ruleset 1
type replicated
min_size 2
max_size 10
step take default
step chooseleaf firstn 0 type host
step emit
}
On Tue, Jan 8, 2013 at 3:23 PM, Gregory
Yep! The step chooseleaf firstn 0 type host means choose n nodes of
type host, and select a leaf under each one of them, where n is the
pool size. You only have two hosts so it can't do more than 2 with
that rule type.
You could do step chooseleaf firstn 0 type device, but that won't
guarantee a
I appreciate you giving more detail on this. I plan on expanding the
test cluster to 5 servers soon, so I'll just wait until then before
changing the number of replicas.
Thanks,
