Topic: Move server to Proxmox

[beast]

Hi

What is the best method if I like to move my server to Proxmox.

The problem is that I have a space issue and I am unable to do a direct dd copy with the current hardware (just missing a bit of space)

Is it possible to make a fresh installation and then move all files with rsync or a backup option? Currently the server is about 1 TB on a 2 TB disk

Hard to be precise but MigrateHelper is your friend.

https://wiki.koozali.org/Migratehelper

Also these days I keep my OS on a separate 'drive' and just mount the data folders into the OS drive eg:

Code: [Select]

# Mount /dev/vda1
UUID=1234567890 /mnt/data ext4 defaults 0 0

# Bind mount /dev/vda1 includes home files
/mnt/data/files /home/e-smith/files ext4 bind,uquota,gquota,noatime 0 0

To upgrade now I vaguely do something like this:

• I set up a new OS on a new 'drive'
• Create a spare 'drive' and attach to the old server (or a USB)
• Run Migratehelper on the old server to create a backup of just the configs onto the spare 'drive' mounted on the old server
• Mount the spare drive to the new server and restore your settings.
• Bind mount the old disk into the new server.
• Clearout all the old unrequired server folders on the drive and just leave the /home/e-smith/files folder (first time only)

In your scenario you can follow MigrateHelper and SCP the data files to Prox. Note you can also SSH mount your old server to Prox/your new server and then 'copy' across. I have done this before.

If in doubt ask on Rocket - most there use Proxmox.

Once you are on Prox it is much easier to move stuff about.

Not clear what you want to do.  move to a new hardware or keep the same?

if keeping same server, i would suggest to
- backup on external drive using console or migratehelper
- buy new disks install proxmox (as you tel you are missing space, this is time)
- configure a vm with sme 11
- connect disk and restore
 you could reuse the ol disk as extra or at least have them clean im case of catastophic failure during migration.

It is an upgrade so I reuse some of the hardware. I had 2 more or less identical servers. Now I have made one a Proxmox server and the other one is currently running as SME server. This server shall after the move of the OS become a Proxmox backup system.
The main problem is that I am reusing 2 of the 2TB SSD that was used across the servers. And when I set them up in a ZFS raid on the Proxmox the space is smallen than needed for DD copy (just a bit). Half the space is empty space.
My solution right now is to install a temporary 4TB disk and use this as DD target and then use the internal Proxmox tools to move it to the SSD. Was just thinking if there is a better way?

you are posting on sme10. so i assume you were planing to dd a sme10 to the new vm. 


i would again suggest to rather backup and restore to sme11 rc1.  if you want to avoid rc1 then just wait a few weeks before the migration, in the mean time use this time to help testing an verifying  for the release.

Why wait for SME11?

[beast]

And how to backup and restore to SME11?

https://wiki.koozali.org/Migratehelper is our friend.

"Restore
First step will be to simply use the console restore with the obtained smeserver.tgz.
We expect you handle the transfer either using a USB disk..."

I'll do another test migration soon but I think RC1 is production ready.

[Jean-Philippe Pialasse]

And how to backup and restore to SME11?

in the same way as usual to backup and restore from one major version to another


console
migratehalper and console
backup 2 workstation
any other documented way on wiki.


my preference goes indeed to migrate helper + rsync of big chunk of data. so your server is up soonish even if data is not fully available at start.  but all depends if you need tue drives to reinstall the proxmox

[beast]

I try to install SME11 under Proxmox but get the following problem during installation (see attachment picture)?

[beast]

Made the installation this time (no change).

Have the problem now that every time i reboot it ask to restore from backup. E.g. it does somehow not remember the config. Tried to bypass the restore and key in manually but same behavior as when I restore from backup?
