XCP-ng 8.1 Release Candidate now available!

Biggen

Oh, I see. You are talking about migrating everything including XOA to NFS and running it from there while I'm destroying/recreating the SR, and then moving everything back.

Yeah I get it now.

Biggen

Upgrading to 8.1 from 8.0 went just fine. Thanks for the help @Danp. Moving everything to a temporary NFS share worked easy (although one stubborn VM couldn't be migrated for some reason. I had to perform a copy instead).

Just be aware if you pass through any disks or have a local ISO SR setup in dom0, you will have to set it back up again. The pass through disks are easy since the data itself on the drives isn't touched. You just have to pass them back through and reattach to the appropriate VM. The local ISO SR is another story since it gets wiped if it resides in dom0. Not a big deal. Just have to copy back into it the installation ISOs required and add it back in the storage menu.

local ISO SR

Why not just setup an NFS one?

Biggen

@Danp I should but I use it so seldom that I just have never got around to it. Might as well now so I only have to build it again from scratch just this once!

Import (in XO and XCP-ng center) / restore from back up is broken. It works with 8.1 RC1 but with latest patches applied or prefinal 3 it fails.

Think this is the relevant bit of the log,

@jmccoy555 Just tested a VM restore and it worked fine for me. <shrug>

stormi

@jmccoy555 @Danp what's your XAPI version?

rpm -q xapi-core xapi-xe xapi-tests

BenjiReis

Also which version of XO are using? What kind of backup were you trying to restore?

Danp

# rpm -q xapi-core xapi-xe xapi-tests
xapi-core-1.214.1-2.4.xcpng8.1.x86_64
xapi-xe-1.214.1-2.4.xcpng8.1.x86_64
xapi-tests-1.214.1-2.4.xcpng8.1.x86_64

BenjiReis

@jmccoy555 Can we have the full XO log with the name of the action that created the error?
Can we have the XCP-ng log as well corresponding to this error?

Works - Fresh RC1 install as a VM
xapi-core-1.214.1-2.2.xcpng8.1.x86_64
xapi-xe-1.214.1-2.2.xcpng8.1.x86_64
xapi-tests-1.214.1-2.2.xcpng8.1.x86_64

Fails - The above with patches applied
xapi-core-1.214.1-2.5.xcpng8.1.x86_64
xapi-xe-1.214.1-2.5.xcpng8.1.x86_64
xapi-tests-1.214.1-2.5.xcpng8.1.x86_64

I have tried a restore from a scheduled XO back up.

I also have exported the VM from XO as a .XVA and tried importing with XO and XCP-ng center, both fail but work with 8.1 RC1 before patches.

xo-server 5.57.3
xo-web 5.57.1

I'll have to dig the logs out later if still required.[0_1585573752708_2020-03-30T13_19_28.603Z - XO.log](Uploading 0%)

BenjiReis

@jmccoy555 Thanks for the info, can you precise what kind of backup you were using? Delta? continuous replication?

thanks

jmccoy555

@BenjiReis 'Backup' and 'Export' from the VM screen in XO.

BenjiReis

Ok thanks!

olivierlambert

Good news! I'm able to reproduce the issue

My server is fully patched (no updates showing in XO). Can someone please explain why these updates aren't showing up for me?

jmccoy555

Don't suppose there's a quick way to rollback is there?

Danp

@jmccoy555 You could try the following (untested!) --

yum downgrade xapi-core-1.214.1-2.4.xcpng8.1.x86_64 xapi-xe-1.214.1-2.4.xcpng8.1.x86_64 xapi-tests-1.214.1-2.4.xcpng8.1.x86_64

Not sure if there are other packages that would need rolled back as well.

jmccoy555

@Danp

rpm -q xapi-core xapi-xe xapi-tests
xapi-core-1.214.1-2.4.xcpng8.1.x86_64
xapi-xe-1.214.1-2.4.xcpng8.1.x86_64
xapi-tests-1.214.1-2.4.xcpng8.1.x86_64

on my other physical host and that is causing me issues. Guess I'll have to do a reinstall back to RC1.

Fixed packages will be available shortly. Thanks for finding this important regression.
