[Upgrade][Gluster] Host moves to Non operational after vdsm upgrade due to a missing gluster-cli package
Last modified: 2016-03-09 16:54:12 EST
Description of problem:
When upgrading an host which has a gluster SD, from vdsm 4.16.x to 4.17.x, it moved to a "Non operational" state.
Version-Release number of selected component (if applicable):
Upgrade: vdsm-4.16.30-1.el7ev.x86_64 to: vdsm-4.17.12-0.el7ev.noarch
Steps to Reproduce:
1. Install a RHEV host with vdsm-4.16.30-1.el7ev.x86_64
2. Add a gluster SD
3. Upgrade the host to vdsm-4.17.12-0.el7ev.noarch
Host moves to Non operational due to this (supervdsm.log)

Can be easily workaround by "yum install glusterfs-cli"

vdsm should have a Requires on glusterfs-cli.
Nir, I think this was not added due to the package not being available on ppc, IIRC. But what about other arch?

Vdsm was converted to noarch package, so we don't have any way now to
require arch specific packages.
I have set of patches fixing this here:
It was created for ceph packages, but will serve also gluster package
when it is done.
For the upstream VDSM project, VDSM requires glusterfs-cli (see 766a54776555e6303b4ceae593c41bbfb0c764ae and b9b06b6342829b29ab29dc9d2a972712133c3a34).
On RHEV, we cannot require glusterfs-cli, as its not delivered in the rhel-server channel - only in rhel-optional or RHGS' channel.
Therefore, the only thing we can do is have a release note, which we already provided in bug 922744.
This should be fixed on master:
gluster command line is *not* required now. When it exists, we can provide
validation of gluster volume configuration, and add automatically backup
servers. When it is not available, the system should behave in the same way
as in 3.5.
