Re: [ovirt-users] restricting release version when upgrading/installing Linux Enterprise hosts?
Thanks!
Maybe the cinder/ceph setup is not so "very" customized, but we are
using a current librbd1 (12.2.x) instead of the version in CentOS 7. For
this we had to switch from upstream Ceph RPMs (depending on
lttng-ust/userspace-rcu from epel repo) to self-compiled Ceph RPMs
(depending on lttng-ust/userspace-rcu from centos-ceph-luminous repo) on
virtualization hosts when upgrading to oVirt 4.2. We have been using a
Ceph 12.2.x cluster as storage with oVirt 4.1 (now 4.2) for quite some
time with good results. Of course we would be happy to see further
Cinder integration in oVirt ("Future Work?" on
https://ovirt.org/develop/release-management/features/storage/cinder-integration/),
but we understand that oVirt is focused on Gluster.

Hi,
Newer Vdsm will work with older engine, so in your case, I don't see any
reason not to update the Vdsm.
BTW, can you describe what do you mean by "a very customized cinder/ceph
setup" ?
Thanks,

Hi,
is it possible to restrict the oVirt version when installing or
upgrading CentOS hypervisor hosts? let's say: 4.2.3 is already
released, but i want to update/install certain hosts only to version
4.2.2 to have the same version in the whole cluster/data center. i
know i could to this manually with yum and specifying rpm package
versions but is there an "oVirt way"? or is this not necessary at
all and newer hosts will always work smoothly with older engine and
other hosts? still i think this is a topic that must be of interest
to others.
besides that: please excuse my impatience sometimes, my upgrade of
our oVirt installation (4.1.9 to 4.2.2) worked perfectly, even with
a very customized cinder/ceph setup. thanks a lot for this great
software!
