[ovirt-devel] Using libgfapi on Gluster Storage Domains

Hi everyone, if you want to try and use the libgfapi support included in qemu when accessing volumes on gluster storage domains you can try to apply this patch: http://gerrit.ovirt.org/33768 As far as I know Jason Brooks already tried it and he reported a positive feedback. What has been tested so far is: - qemu uses libgfapi to access the disks on gluster storage domains - hotplug of disks on gluster storage domains works as expected (libgfapi) - hotunplug works as expected (no failure when removing a disk that is using libgfapi) - live snpashots work as expected - disks of vms started before this patch are not affected (they won't use libgfapi since there's no way to do an hot swap) One major flow that is yet untested is live storage migration. Remember that you may need to do some special configuration on your gluster volumes (most notably the allow-insecure ports option) as described here: http://www.ovirt.org/Features/GlusterFS_Storage_Domain Please try and test the patch if you're interested and report your feedback. Thanks, -- Federico
