XCP-ng 8.3 public alpha 🚀
-
That's really weird, I don't understand how it's possible to install a fresh XCP-ng (without doing any upgrade) with the old partition layout
-
@olivierlambert
Neither do I.
I thought I might have taken an old SSD, but that wasn't the case, the part was new.
Well, sometimes you lose and sometimes the others win.
Fresh installation
But thanks anyway -
Adding @yann in the conversation, so we need to check if it's even possible the old layout could be created in the installer code.
Did you use the regular installation or something else? (answer file, automated install etc.)
-
@jhansen I'd suggest booting off some Linux rescue disk and just redoing all the partitions manually. I ran into an upgrade issue once on a Dell box because of some stupid little extra utility partition they had in there. See: http://xenserver.pl/author/tobias-kreidl
Look for "The (In)famous Dell Utility Partition." -
@olivierlambert
Unfortunately, I only keep the latest version of the iso files. I have the xcp-ng-8.2.1.iso here and I think that was it, but it could also have been the previous version. -
@jhansen Any old Linux distribution recovery-like boot disk should work, as long as you can get to the partitioning app.

@tjkreidl
Mayby you are on the right trace.
It is a Dell Server.
This time i will wipe the disk before installation.
As the Data is on other disk i will try to mount then afterwards.
Thanks -
@tjkreidl
Do you think a simple reseize of the different partition will do it? -

ThanksI am willing to bet you got bitten by the Dell utility partition disk issue. And, yes, best to wipe it out. Or delete it and redo one of the other partitions. But frankly, you will really want the new 36.5 GB total layout with the dual 18GB partitions, etc., that was mentioned above. You will want the right order of partitions to match what the XCP-ng installation wants to do at some point, but it should redo the layout I hope once you get rid of that extra Dell partition. Check out what I did in my article referenced above:
"The solution was simply to delete that sda1 partition altogether using fdisk and re-install. Deleting the partition can be performed live on the host prior to the installation process." -
@tjkreidl
Naturally partition and filesystem. -
@tjkreidl
Just got an idea, but will it work?
wipe disk
Fresh installation
Restore Metadata from XO Backup
Will that work? -
@jhansen If you have the full metadata, I would think that's possible. What about any VM backups, custom network settings, etc.? Lots to make sure you have before anything that drastic.

Although it's my test lab, I have a backup of everything. I'm something of a burned child with many years of bad experience.
Unfortunately it would take a few days to play everything back.
But I'll get a new SSD and give it a try.
But first thanks for the help, I'll write if it worked.

@stormi Finally updated my two host playlab from 8.2.0 fully patched to 8.3.0-alpha2 using the ISO method followed by installing available patches using XO from source.
As boring as it is, I have nothing to report other than that the update of my low-tech hosts has worked (Dell Optiplex 9010, Intel i5-3550 CPU, 32GB RAM, Intel S3700 100GB SSD for boot, Samsung 860 EVO 500GB SSD for local SR, Intel X520-DA1 10G). You wouldn't believe it, but sometimes boring is good
.I'll report back if anything comes up in day-to-day operations

Hello
So now the 8.3 is running with all updates.
Where the old partition table came from is still a mystery to me but it could be something to do with Dell Utility as tjkreidl assumed.
No idea....
I took all disks out of the server and wiped the boot disk with zeros and then installed a new fresh 8.2.1. Now I also had the 18GB partitions.
I then did a metadata restore via XO. (the trick with renaming the backup folder from the old UUID to the UUID of the new installation)
All disks back in the server and then all VM and functions of the server checked, everything ok.
USB stick with the 8.3 version in - and the update ran without any problems. Then yum update, no problems here either.
All VMs are running.
I've only noticed one thing so far:
I set up one of my 10GBit network cards with SR-IOV, which no longer worked. I deleted it and created a new one, then it worked again. I have 2 Intel I350 gigabit adapters in the server, they can no longer do SR-IOV.
Now it's time to stress test the server with Windows, Linux, databases and video conversion. I'll let the CPU's run at 70-80% load for a week and also let the network cards and disk sweat. We'll see.Thanks again for the help.
Greetings JörgTest server:

@tjkreidl
Hello again,
thanks for your help, you put me on the right path.
I wrote to Olivier what I dit.
Greetings Jörg -
@jhansen Great news! Maybe the SR-IOV issue is driver-related - is there a newer driver available or perhaps some setting in the BIOS?
And, yes, I bet wiping all the old partitions made a big difference.
-
@tjkreidl
Yes I believe that too -
Great news!
