Hi Andrija,
I've got at least two more stories of similar nature. One is my friend running
a ceph cluster and one is from me. Both of our clusters are pretty small. My
cluster has only two osd servers with 8 osds each, 3 mons. I have an ssd
journal per 4 osds. My friend has a cluster of 3 mons
Hi Andrei, nice to meet you again ;)
Thanks for sharing this info with me - I though it was my mistake by
introducing new OSD components at the same time - I though that since it's
rebalancing, let's add those new OSD, so it also rebalances - so I don't
have to cause 2 data rebalancing - but duri
Hello,
new firefly cluster, currently just 1 storage node with 8 OSDs (3TB HDDs,

Now this is the 2nd incarnation if this "cluster", I did a first one a few
days ago and this did NOT hap

Hi All,
Just a quick question for the list, has anyone seen a significant increase in
ram usage since firefly? I upgraded from 0.72.2 to 80.3 now all of my Ceph
servers are using about double the ram they used to.
Only other significant change to our setup was a upgrade to Kernel
3.13.0-30-gen
Quenten,
It has been noted before and I've seen a thread on the mailing list about it.
In a long term, I've not noticed a great increase in ram. By that i mean that
initially, right after doing the upgrade from emperor to firefly and restarting
the odd servers I did notice about 20-25% more r
Hi Karan!
Due to the late reception of the login info I 've also missed
a very big part of the webinar.
They did send me an e-mail though saying that they will let me know as
soon as
a recording of the session will be available.
I will let you know again then.
Best,

It looks like those were not added when the build finished. That just

I've added some additional notes/warnings to the upgrade and release

If there is somewhere else where you think a warning flag would be useful,
let me know!
Generally speaking, we want to be able to cope with

There's no reason you can't create another set of zones that have a master

write to http://us-west-2.cluster/, and users that need low latency to

There are some brand new crush tunables that fix.. I don't even remember
off hand.
In general, you probably want to stay away from 'optimal' unless this is a
fresh cluster and all

Hi Guys,
I am using ceph firefly on a three-node-cluster (all of them are
storage-servers AND monitors) with rhel 6.5. Right now I've updated ceph from
version from 0.80.2 to 0.80.3.
But during update something strange happened. After having updated node2 I
stopped ceph (osd and mon) on node 1.

This is just the output if it fails to connect to the first monitor it
tries (in this case, the one that isn't running). If you let it run
for a while it should time out after 15 seconds or something, pick a
different monitor, and succeed.

Hi Guys,
me again.
In the documentation about adding/removing monitors (see here:
http://ceph.com/docs/master/rados/operations/add-or-rm-mons/ ) I've found
something which should be written somehow noob-safe.
I've used ceph version 0.80.2 on three rhel6.5 nodes.
