Hello all,

I believe I have fixed this for several hosts - or at the very least I have successfully upgraded from 4.2.3 to 4.2.5 successfully on servers that previously failed.

This is documented from memory, but I believe I didn't do anything else.

What I did is, first removed the old LV for the new install and/or any old installs also (we had one on 4.2.2) like this:

lvremove /dev/onn/ovirt-node-ng-4.2.x
lvremove /dev/onn/ovirt-node-ng-4.2.x+1

lvremove /dev/onn/var_crash

The nodes were running with 4.2.3, and were were previously on 4.2.2. The LVs remained. I had previously removed only the 4.2.2 LVs & yum updated, and I do not believe this caused an upgrade to complete properly (ie: grub wasn't updated at the very least).

In my searching, I noticed a suggestion somewhere about removing grub entries and the old info in /bootovirt-node-ng-4.2.x*

Removing the directory from the previous install in /boot & manually removing the old boot-loader info in /boot/grub2/grub.cfg, along with any other LVs that may have remained from previous installs seems to "work" -- the yum update following doing this succeed & grub is updated.

Following this I upgraded from 4.2.3 to 4.2.5 on several hosts, and the process went perfectly on 3 in a row that previously failed.

I believe I can now successfully upgrade our remaining hosts from 4.2.3 to 4.2.5, I'm happy to provide more info it it will help identify exactly what caused this.

Thanks,

Matt

PS- I will also be in #ovirt for about 3 hours if anyone would like to work there with me

Hi Matt,

Can you attach the output from the following line

# semanage permissive -a setfiles_t

Thanks,

Yuval.

Hello all,

I've emailed about similar trouble with an oVirt Node upgrade using the ISO install. I've attached the /tmp/imgbased.log file in hopes it will help give a clue as to why the trouble.

Since these use NFS storage I can rebuild, but would like to know, ideally, what caused the upgrade to break.

Truthfully following the install, I don't think I have done *that* much to these systems, so I'm not sure what would have caused the problem.

I have done several successful upgrades in the past and most of my standalone systems have been working great.

I've been really happy with oVirt, so kudos to the team.

Thanks for any help,

Matt
