Hi guys,
Could someone explain what's the new perf stats show and if the numbers are

I am concerned about the high fs_commit_latency, which seems to be above 150ms

You manually have to instruct the OSD

Hi All,
There is a new release of ceph-deploy, the easy deployment tool for Ceph.
This is mostly a bug-fix release, although one minor feature was
added: the ability to
install/remove packages from remote hosts with a new sub-command: `pkg`
As we continue to add features (or improve old ones) we

Run
'ceph osd crush tunables optimal'
or adjust an offline map file via the crushtool command line (more
annoying) and retest; I suspect that is the problem.

Hi all
I have a problem with gateway and swift.
When i try ti get by wget, curl, or swift command, I have no problem to get my
file ! But when I tried to do it directly in my browser it stopped between 6
and 40 seconds.
Ceph.conf:
[client.radosgw.gateway]
host = p1
keyring = /etc/ceph/keyr
I figured out why this was happening. When I went through the quick start
guide, I created a directory on the admin node that was /home/ceph/storage
and this is where ceph.conf, ceph.log, keyrings, etc. ended up. What I
realized though is that when i was running the ceph commands on the admin
nod

Hi,
I was wondering if there are any procedures for rebooting a node? Presumably
when a node is rebooted, Ceph will lose contact with the OSDs and begin moving
data around. I’ve not actually had to reboot a node of my cluster yet, but may
need to
