Correct, that's basically it.

dovecot + cephfs - sdbox vs mdbox
I'm sending this message to both dovecot and ceph-users ML so please don't
mind if something seems too obvious for you.
Hi,
I have a question for both dovecot and ceph lists and below I'll explain
what's going on.
Regarding dbox format (https://wiki2.dovecot.org/MailboxFormat/dbox), when
using sdbox, a new file is stored for each email message.
When using mdbox, multiple

is the vfs_ceph supporting quota set on a directory inside cephfs?

MacOS clients - best options
Hi list,
we have migrated a single node Samba server from Ubuntu Trusty to a
3-node CTDB Cluster on Debian Bullseye with Sernet packages. Storage is
CephFS. We are running Samba in Standalone Mode with LDAP Backend.
Samba Version: sernet-samba 99:4.18.2-2debian11
I don't know if it is relevant here's how we have mounted CephFS on the
samba nodes:

[ceph-users] dovecot + cephfs - sdbox vs mdbox
Thanks Jack.
That's good to know. It is definitely something to consider.
In a distributed storage scenario we might build a dedicated pool for that
and tune the pool as more capacity or performance is needed.

Gluster -> Ceph
Hi all,
I am looking in to ceph and cephfs and in my
head I am comparing with gluster.
The way I have been running gluster over the years
is either a replicated or replicated-distributed clusters.
The small setup we have had has been a replicated cluster
with one arbiter and two fileservers.
These fileservers has been configured with RAID6 and
that raid has been used as the brick.

Samba and CEPH
Greetings all!
I am in the process of deploying a POC around SAMBA and CEPH. I'm
having some trouble locating concise instructions on how to get them to
work together (without having to mount CEPH to the computer first and
then exporting that mount via SAMBA).
Right now, my stopper is trying to locate ceph.so for x64 CentOS 6.5.

Gluster -> Ceph
Big raid isn't great as bricks. If the array does fail, the larger brick means much longer heal times.
My main question I ask when evaluating storage solutions is, "what happens when it fails?"
With ceph, if the placement database is corrupted, all your data is lost (happened to my employer, once, losing 5PB of customer data). With Gluster, it's just files on disks, easily

virsh not connecting to libvertd ?
Just found my issue.
After I removed the cephfs mounts it worked!
I will debug ceph.
I assumed because I could touch files on mounted cephfs it was working.
Now virsh list works!
thanks

CTDB over WAN Link with LMASTER/RECMASTER Disabled
Hi,
I came across the 'CTDB_CAPABILITY_LMASTER=no' and 'CTDB_CAPABILITY_RECMASTER=no' options in my quest to salvage a rather poorly performing CTDB cluster over Ceph(fs). Unfortunately, the docs provide not enough information for a clustering noop like myself. Would there be any benefit to disabling those options for a branch office node on a high-latency WAN connection?

it's a known subtle Ceph issue I'm afraid:

Ceph RBD locking for libvirt-managed LXC (someday) live migrations
Hi,
I'm trying to build an active/active virtualization cluster using a Ceph
RBD as backing for each libvirt-managed LXC. I know live migration for LXC
isn't yet possible, but I'd like to build my infrastructure as if it were.
That is, I would like to be sure proper locking is in place for live
migrations to someday take place. In other words, I'm building things as

couple of ceph/rbd questions
Hi, I've recently been working on setting up a set of libvirt compute
nodes that will be using a ceph rbd pool for storing vm disk image
files. I've got a couple of issues I've run into.
First, per the standard ceph documentation examples [1], the way to add a
disk is to create a block in the VM definition XML that looks something
like this:
<disk type='network'
