ne is using that default,
including me. Is there a reason that Straw is favored over Tree other than
it’s just the default. I’m interested in Tree because it looks like it
provides performance improvements over Straw with only a small reorganization
hit when OSD’s fail etc…
Thanks,
Yup I think you are correct, I see this listed under issues

Nice spot - and this is not the first time I've seen a bug due to
incorrect specification of the stripe size for rbd images.

Well, we’re a RedHat shop, so I’ll have to see what’s adaptable from there.

For that matter, is there a way to build Calamari without going the whole
vagrant path at all? Some way of just building it through command-line tools?
I would be building it on an Openstack instance, no GUI. Seems silly to have
to install an entire virtualbox environment inside something tha

Does anybody have an idea what might be wrong here?

our 15.01 charm release - mod-fastcgi was causing so many headaches!
So far in our internal QA cloud its been very reliable running with
civetweb - we run three units of the ceph-radosgw charm frontend by
haproxy + VIP.
I'd +1 switching focus to this approach.

I'm running Ubuntu 14.04 servers with Firefly and I don't have a sysvinit
file, but I do have an upstart file.
"touch /var/lib/ceph/osd/ceph-XX/upstart" should be all you need to do.
That way, the OSD's should be mounted automatically on boot.

COW operations are still troublesome
with ceph? So using a raid1 on each node with btrfs will allow me
to turn off COW if/when those sorts of issues arise.
What I need help with right now is setting up the UUID based /etc/fstab
and suggestions on exactly how to configure ceph(fs).
My desire is to keep the btrfs-gentoo installs stable but to be able
to use ansible or other (ceph based tools) to reconfigure ceph or recover
from ceph failures.

p of Btrfs is the most challenging part of this journey so
far. I use openrc on gentoo, and have no interest in systemd, just so
you know.

Hello,
I was wondering if anyone has Mesos running on top of Ceph?
I want to test/use Ceph if lieu of HDFS.
I'm working on Gentoo, but any experiences with Mesos on Ceph
are of keen interest to me as related to performance, stability
and any difficulties experienced.
op of it.
