Hello,
I found a strange behavior in Ceph. This behavior is visible on Buckets
(RGW) and pools (RDB).

Hi,
For some unknown reason, periodically, the master is kicked out and
another one becomes leader. And then a couple second later, the
original master calls for re-election and becomes leader again.
This also seems to cause some load even after the original master is
back. Here's a couple of

I'm not sure where you are at with forming this. I would love to be considered.
Previously I've contributed commits (mostly CephFS kernel side) and
I'd love to contribute more there. Usually the hardest part about
these kinds of things is finding the time to participate. Since Ceph

Hi all,
we are considering building all SSD OSD servers for RBD pool.
Couple of questions:
Does Ceph have any recommendation for number of cores/memory/ghz per
SSD drive, similar to what is usually followed for hard drives(1
core/1 GB Ram/1Ghz speed)?
thanks,
Sreenath
Right now we're just scraping the output of ifconfig:
ifconfig p2p1 | grep -e 'RX\|TX' | grep packets | awk '{print $3}'
It clunky, but it works. I'm sure there's a cleaner way, but this was
expedient.

I am conincidentally going through the same process right now. The best

Both of those say they want to talk to osd.115.
I see from the recovery_state, past_intervals that you have flapping OSDs.
osd.140 will drop out, then come back. osd.115 will drop out, then come
back. osd.80 will drop out, then come back.
So really, you need to solve the OSD flapping. That
Can you both set Cinder and / or Glance logging to debug and provide some
logs? There was an issue with the first Juno release of Glance in some
vendor packages, so make sure you're fully updated to 2014.2.2

No sure whether it is relevant to your setup or not. But, we saw OSDs are

During root causing we saw continuous dropping of packets in dmesg and may be
because of that osd heartbeat responses are lost. As a

I got the config page to come up by exiting Calamari, deleting the salt keys on
the calamari master ‘salt-key –D’, then restarting Calamari on the master and
accepting the salt keys on the master ‘salt-key –A’ after doing salt-minion and

All,
Apologies for my ignorance but I don't seem to be able to search an
archive.
I've spent a lot of time trying but am having difficulty in integrating
Ceph (Giant) into Openstack (Juno). I don't appear to be recording any
errors anywhere, but simply don't seem to be writing to the cluster if

You should have a config page in calamari UI where you can accept osd nodes
into the cluster as Calamari sees it. If you skipped the little
first-setup window like I did, it's kind of a pain to find.
