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.

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. If disaster

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

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.

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

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'

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

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

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]

Hello List, as anyone tried to install samba with/ontop on a ceph cluster? Regards, Dirk

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

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: (fstab):/samba /srv/samba ceph

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.
