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

Eric, Well, in case where several servers may start the same virtual machines after a reboot for exemple. http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-August/003887.html I've seen this hook here : http://www.wogri.at/en/linux/ceph-libvirt-locking/ But it's a hook... Yes, I may try to write a patch. My coding skills are surely not as good as yours but I 'd be glad to make

Hi, One short question : Is there any chance to see locks on rbd/images in the next release ? Thank you :)

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

Hi Dovecot Users, I?ve configured dovecot dsync replication and I see troubles in the logs and get user complaints which I can?t explain. I found similar threads on this mailinglist, but I couldn?t find a solution anywhere. Does anybody have dsync running without problems on a high volume mailserver? I see the following logs, examples given: Feb 17 18:16:49 dovecot dovecot: imap(zoechi):

Hi, When I enable (and it only happens when it is actually running) replication over TCP my users get duplicate mails via pop3. Here?s what happens: * User gets mail * Mail appears in (Maildir) new/ folder on both replicas * user retrieves mail (retr), calls dele. Mail still exists in new/ folder on both replicas. * user runs retr (and gets the duplicate) and dele a second time, the mail is

Hi, I know this may be very basic question but I need some help . Actually I installed VM using the Xen Administrative console. Now I need to change the configuration file as I need to passthrough (using the pci-hide) a SCSI contoller from Dom0 to DomU. But I couldnot find the configuration file. Where can I find the Configuration file for this DomU? Actually I added the

Hello, I'm trying to integrate HAST to NAS4Free (FreeBSD 9.1-RC3). Now I have created version 9.1.0.1.531. http://sourceforge.net/projects/nas4free/files/NAS4Free-9.1.0.1/9.1.0.1.531/ Basic CARP + HAST + iSCSI target setup can be done, but very frequently I get hastctl hang when called: /sbin/hastctl status /sbin/hastctl dump Is it better for this method not to call from a script? or

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, I'm trying to run virt-sysprep against a disk in Ceph RBD storage but I appear to be unable to do so. The commands (bold) and outputs I've had are: On Ceph node: *virt-sysprep -a rbd://localhost/libvirt-pool/ubuntu-12-04-beanstalk001* libguestfs: new guestfs handle 0x113b060 rbd://localhost/libvirt-pool/ubuntu-12-04-beanstalk001: No such file or directory libguestfs: trace: close

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'

So, even with a particular user only connecting to one node in the pair, you still see the issue? I'm not seeing that in my setup. I only see it when concurrently connecting the same user to two different nodes in the pair.

Hi guys, I have started preparing a library of PV-HVM templates for use on Xen 4.X+ and PVOPS dom0. This was brought up late last year as something that would make Xen alot easier for beginners to try. They are also great for testing - I will be setting up some stuff to do automatic testing of distro kernel compatibility against xen-unstable. Mirror page is here:

how to use python-guestfs to access rbd device? The function i found is g.add_drive_opts, but i dono know how it receive ceph's configuration. I found this link http://rwmj.wordpress.com/2013/03/12/accessing-ceph-rbd-sheepdog-etc-using-libguestfs/ Is that the only way i should use to access ceph rbd? Can we use python-guestfs to get the same effect? Thanks
