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

Samba 4.10.6 for rhel7/centos7 rpms
Hi everyone,
I've posted some updated source and binary rpms following the release of
updates by the samba project. Updated rpms include samba-4.10.6 and
ldb-1.5.5.
Here are the links:
- http://nova.polymtl.ca/~coyote/dist/samba/samba-4.10.6/RHEL7
As usual, these work fine for me (4.10.6) but YMMV. Please do report
issues if you find some.
Regards,
Vincent

[ceph-users] dovecot + cephfs - sdbox vs mdbox
Hi,
some time back we had similar discussions when we, as an email provider,
discussed to move away from traditional NAS/NFS storage to Ceph.
The problem with POSIX file systems and dovecot is that e.g. with mdbox
only around ~20% of the IO operations are READ/WRITE, the rest are
metadata IOs. You will not change this with using CephFS since it will
basically behave the same way as e.g. NFS.
We

That's probably doable but you'd have to BETA-test for me since I don't
have a working ceph cluster at home. The information

[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.

ceph_vms performance
Hi,
I'm testing out ceph_vms vs a cephfs mount with a cifs export.
I currently have 3 active ceph mds servers to maximise throughput and
when I have configured a cephfs mount with a cifs export, I'm getting
a reasonable benchmark results.
However, when I tried some benchmarking with the ceph_vms module, I
only got a 3rd of the comparable write throughput.
I'm just wondering if

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

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:

Can you verify currently defined libvirt secret provides valid Cephx auth?
As the subject suggests, I am wondering if its possible to verify if the
currently defined libvirt secret provides valid authentication via Cephx to
a Ceph cluster?
I ask because ideally I would like to verify that the given cephx
credentials in my libvirt secret are valid before I even attempt the virsh
attach-device on the domain.
I tried searching for a solution to this, but I can't seem

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:

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?

Samba 4.10.6 for rhel7/centos7 rpms
Hi Konstantin,
Thank you for the diff. I will review it and merge it today.
About the missing directories, I think it may be doable to add them to the
'ctdb' rpm. As I'm not using ctdb, what should the ownership/permissions
be for those directories?

Vincent

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
if I were
