[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

[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. 1.

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. [2014/02/26 15:05:23.923617, 0]

Using libvirt to access Ceph RBDs with Xen
Hi everybody, my background: I'm doing Xen since 10++ years, many years with DRBD for high availability, since some time I'm using preferable GlusterFS with FUSE as replicated storage, where I place the image-files for the vms. In my current project we started (successfully) with Xen/GlusterFS too, but because the provider, where we placed the servers, uses widely CEPH, we decided to

Gluster -> Ceph

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. If disaster
