[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.

[ceph-users] dovecot + cephfs - sdbox vs mdbox
Hello Jack,
yes, I imagine I'll have to do some work on tuning the block size on
cephfs. Thanks for the advise.
I knew that using mdbox, messages are not removed but I though that was
true in sdbox too. Thanks again.
We'll soon do benchmarks of sdbox vs mdbox over cephfs with bluestore
backend.
We'll have to do some some work on how to simulate user traffic, for writes
and readings.

Libvirt guest can't boot up when use ceph as storage backend with Selinux enabled
Hi there,
I met one problem that guest fail to boot up when Selinux is enabled with guest storage
based on ceph. However, I can boot the guest with qemu directly. I also can boot it up
with Selinux disabled. Not sure it is a libvirt bug or wrong use case.

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.
