XCP-ng 8.3 public alpha 🚀
@olivierlambert Yes, I had been doing this also for quite some time. It was certainly one of the most requested features. It also felt a bit 'brute force' to me so would be nice to use it built in.
@olivierlambert Well.. I have been doing the occasional "yum update" with no new problems. Everything is working great, but I still have that re-scanning of the FS every 30 seconds.. Not impacting anything but just a little weird...
What is current status? What is the rough expectation of next alpha/beta release
The next planned release should be the first beta. There's no precise ETA yet, but first quarter of 2023 is a likely window.
Applying updates regularly on top of the alpha will also give you the same end-result.
There are a lot of updated packages that are being prepared. They're currently in the
xcp-ng-testingyum repository, because we haven't had time to test them all in our internal CI. All I could assess is that they install well (
yum update --enablerepo=xcp-ng-testing) and that the server I installed them to rebooted without any visible issue. Once tested, early January, they'll be moved to the
xcp-ng-baserepository and offered as updates to anyone running
yum updateon their 8.3. If you want to give it a go ahead of time, you can install them and see if everything works well or not, so that we can quickly work on any issues early January.
Recent work on 8.3 touched:
- the installer (soft RAID support improvements, IPv6 support, contribution of various small improvements to upstream repositories...)
- automated installation ISO generation
- adding memtest86+ to the installer, both in BIOS and UEFI modes
- upgrading all packages to the same level as Xenserver 8 Stream's (that's the new name for Citrix Hypervisor 8 Cloud) preview update channels - we had 4 months of changes to catch up with.
- ongoing work with XenServer on the python2 to python3 transition
- work on UEFI certificate handling, to reach a stage where it answers both XenServer's and our needs
- and more.
I have some trouble with update from 8.2 to 8.3
I boot the installation from USB with Image xcp-ng-8.3.0-alpha2.
Everything works until I get to the installation. The backup of the old version is still made, then this error message appears:
Old partition layout is unsupported, run prepare_host_upgrade and try again. Reboot
The 8.2 installation is a 3 month old fresh installation, I doubt there is an old partition type in this 8.2 version.
I removed all disks except the boot disk which only contains the XCP-NG system. Still the same error.
The partition structure of the disk is as follows:
Model: ATA TS512GSSD720 (scsi)
Disk /dev/sda: 512GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags: pmbr_boot
Number Start End Size File system Name Flags
4 1049kB 538MB 537MB bios_grub, legacy_boot
1 538MB 4295MB 3757MB ext3
2 4296MB 8590MB 4294MB ext3
3 8591MB 512GB 504GB lvm
Does anyone have an idea what's going wrong.
I don't want to do a fresh installation because then I have to restore a lot of data. It's my test machine and I have a backup, but with 29 TB it takes days to restore and without data there is little point in testing 8.3.
Can you give the output of
lsblk, it's more readable to me
Does this help?
sda 8:0 0 477G 0 disk ├─sda4 8:4 0 512M 0 part ├─sda2 8:2 0 4G 0 part ├─sda3 8:3 0 469G 0 part │ └─XSLocalEXT--d7a8bce5--29b3--5d83--f41f--5307f2e1b1bb-d7a8bce5--29b3--5d83--f41f--5307f2e1b1bb 253:0 0 468.9G 0 lvm /run/sr-mount/d7a8bce5-29b3-5d83-f41f-5307f2e1b1bb └─sda1
This is the old partition scheme
It can't be a fresh install, it's not possible.
edit: ah wait. Can you do a
edit 2: a basic lsblk should display where the partition is mounted, did you copy/pasted everything?
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.
Sorry I miss one line:
└─sda1 8:1 0 3.5G 0 part /
You should have 2x 18G partitions (/ and a backup one), 1x 4G partition (/var/log) and a 512MB partition (/boot)
Boot has 537MB
/ has 3757MB
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)
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.
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
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.
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."
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.
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.
