This is the old partition scheme

It can't be a fresh install, it's not possible.

edit: ah wait. Can you do a mount command?

edit 2: a basic lsblk should display where the partition is mounted, did you copy/pasted everything?

@olivierlambert
Thanks for help by the way

I'am shure that it is a new installation from 3 month ago, it is a new Server and I bought it 3 month ago.

regards Joerg

@olivierlambert
Sorry I miss one line:
└─sda1 8:1 0 3.5G 0 part /

olivierlambert

You should have 2x 18G partitions (/ and a backup one), 1x 4G partition (/var/log) and a 512MB partition (/boot)

jhansen

@olivierlambert
My
Boot has 537MB
/ has 3757MB
Backup 4294MB

Okay so this is the old partition scheme. Can you repeat exactly what did you do with this machine? I mean initially. I don't know how to even get the old partition scheme in the first place with XCP-ng (there's 0 edition of XCP-ng with this old partition scheme, it's only before XenServer 6.5)

jhansen

@olivierlambert
I disable all hard drives and put in a new sda and do a fresh installation.
So I can always go back if something doesn't work out.
In any case, thanks for the help.
Regards Joerg

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

jhansen

@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

olivierlambert

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.)

tjkreidl

@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."

jhansen

@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.

tjkreidl

@jhansen Any old Linux distribution recovery-like boot disk should work, as long as you can get to the partitioning app.

jhansen

@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

jhansen

@tjkreidl
Do you think a simple reseize of the different partition will do it?

I 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."

jhansen

@tjkreidl
Naturally partition and filesystem.

jhansen

@tjkreidl
Just got an idea, but will it work?
wipe disk
Fresh installation
Restore Metadata from XO Backup
Will that work?

tjkreidl

@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.
