Hi All,
There were 2 learnings from BZ
https://bugzilla.redhat.com/show_bug.cgi?id=988299
1) Gluster RPM deps were not proper in VDSM when using Gluster Storage
Domain. This has been partly addressed
by the gluster-devel thread @
http://lists.gnu.org/archive/html/gluster-devel/2013-08/msg00008.html
and will be fully addressed once Gluster folks ensure their packaging
is friendly enuf for VDSM to consume
just the needed bits. Once that happens, i will be sending a patch to
vdsm.spec.in to update the gluster
deps correctly. So this issue gets addressed in near term.
2) Gluster storage domain needs minimum libvirt 1.0.1 and qemu 1.3.
libvirt 1.0.1 has the support for representing gluster as a network
block device and qemu 1.3 has the
native support for gluster block backend which supports gluster://...
URI way of representing a gluster
based file (aka volume/vmdisk in VDSM case). Many distros (incl.
centos 6.4 in the BZ) won't have qemu
1.3 in their distro repos! How do we handle this dep in VDSM ?
Do we disable gluster storage domain in oVirt engine if VDSM reports
qemu < 1.3 as part of getCapabilities ?
or
Do we ensure qemu 1.3 is present in ovirt.repo assuming ovirt.repo is
always present on VDSM hosts in which
case when VDSM gets installed, qemu 1.3 dep in vdsm.spec.in will
install qemu 1.3 from the ovirt.repo
instead of the distro repo. This means vdsm.spec.in will have qemu >=
1.3 under Requires.
Is this possible to make this a conditional install? That is, only if
Storage Domain = GlusterFS in the Data center, the bootstrapping of host
will install the qemu 1.3 and dependencies.
(The question still remains as to where the qemu 1.3 rpms will be available)
What will be a good way to handle this ?
Appreciate your response
thanx,
deepak
