Hello Using two file server with samba 4.12.6 running as a CTDB cluster and trying to share a specific path on a cephfs.

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

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.

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]

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. Enable Selinux # getenforce && iptables -L Enforcing Chain INPUT (policy ACCEPT) target prot opt source destination

TLDR: Why is virsh migrate --persistent --live domain qemu+ssh://root@host/system --xml domain.ceph.xml not persistent and what could i do about it? Hi, after years of beeing pleased with local storage and migrating the complete storage from one host to another, it was time for ceph. After setting up a cluster and testing it, its time now for moving a lot of VMs on that type of storage, without

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.

After running ceph on XFS for some time, I decided to try btrfs again. Performance with the current "for-linux-min" branch and big metadata is much better. The only problem (?) I''m still seeing is a warning that seems to occur from time to time: [87703.784552] ------------[ cut here ]------------ [87703.789759] WARNING: at fs/btrfs/inode.c:2103

But the changes i did to domain.ceph.xml

Hello, I would like to use RBD Format 2 images so I can take advantage of layering. However, when I use "qemu-img create -f rbd rbd:data/foo 10G", I get format 1 RBD images. (Actually, when I use the "-f rbd" flag, qemu-img core dumps, but it looks like that feature may have been deprecated [1]) Is there any way to have qemu-img create RBD Format 2 images or am I better off

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

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

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

[Note: This message has also been sent to ceph-devel@vger.kernel.org & puppet-openstack@puppetlabs.com] Hi, I''m currently working on writing a Puppet module for Ceph. As after some research I found no existing module, I''ll start from scratch but I would be glad to hear from people who would already have started working or this or having any idea or pointers regarding this
