[cisco-voip] [QUARANTINE] Re: partitions unaligned is unavoidable for upgrades to 9.1.2

[Ryan Ratliff (rratliff)]

+1

There were bugs in some of the early OVAs that would result in partitions being unaligned.  There are some actions that would result in partitions becoming unaligned (format, etc) on 8.0 and 8.5.
Every jump upgrade will absolutely result in unaligned partitions (because the 7.x installer doesn't create aligned partitions).

Outside of jump there is nothing special about a 9.1(2) upgrade that creates unaligned partitions.  We simply added code to check for it and report in both CCMAdmin and in 'show hardware'.  If you are seeing this on an existing virtualized deployment you were unaligned before the upgrade.

This would be correct the code in the OS didn't handle alignment properly until the first VMware kosher release 8.0.2 or 3 if I remember right. So no matter if the ova is right or not as soon as an earlier release starts  up it moves things out of alignment somehow.



If you have access to the partner community there were VoEs when jump upgrades came out where it was explained in depth.



Out of alignment has caused some bad performance issues in installs and hence the check was added  and the requirement for DRS restore to a clean built 9.1.2 VM for jump upgrades.

Upgraded a few weeks ago from 8.6.2 to 9.1.2 and it was fine... I did a jump last month from 7.1.5 to 9.1.2 and hit it.. be interested too see if this only occurs on Jumps or if anyone is seeing it on direct upgrades as well.

You risk being “Unsupported” if you call TAC.  I would fix it before going into production.

I understood it was an OVA issue but it can’t be totally that, since I used the “fixed” OVA, never touching the OVA version that created the problem.

Yep.

Does anyone know if the unaligned partitions happens on a 9.1.1 to 9.1.2 upgrade? I have been putting it off for this reason of the extra server rebuild/restore. Kind of waiting for 10.x to do it.  I know 9.1.2 adds the warning about it.

Unaligned partitions is ok to run on, just has performance impact from my understanding.

So based on the support forums there is no “partitions unaligned” workaround for upgrades.  You are going to have to DRS Export 9.1.2 and DRS Import it back in for a upgrade.  I had planned for DRS rebuild based on the CCM release notes for 9.1.2 but was hoping there was a way to avoid it.

I built my new 7.1.5 using a “fixed OVA” but that doesn’t seem to matter.
