Yes, it's technically possible, as long as the underlying hardware is compatible. For example, you can't put a server using AMD processors into a pool with Intel processors.
The server being moved into the existing pool will lose its local storage and all VMs stored there, so you will need to migrate those VMs to the main pool before the server is merged. Afterwards, you can move them back if desired.
You're running out of memory. Allocate more memory to the VM. I believe the current build requirement is 3GB.
You need a space between the URL and the user name.
Updated Dell R620 / XCP-ng 8.1. Rebooting all VMs now, but they appear to be coming up just fine.
@hvilches said in XCP-ng Center 20.03.00 released:
is-a-template ( RW): true
Looks like this is the culprit...
@flipsidecreations There's a new Netdata plugin, which appears to only be available in XOA Premium edition. It doesn't appear that you will be able to enable the new Advanced Live Telemetry using the versions you are currently running.
@olivierlambert The "quick deploy" via web worked correctly this time 
@spidernin said in Help with delta backups and retention:
Not sure why this is set to 5. I have tried to change it to 7 multiple times (separate issue)
That is benign; it just expands the cron pattern to show you the backup schedule for the number of future events.
13 items? Should be one per day for 7 days.
That's the backup log, not the number of retained backups. You need to set the retention in the schedule associated with the backup job. Currently you have it set to 1. Change that to 7 and you should be all good.

XO from the sources
What version for both xo-server and xo-web? If you haven't updated recently, then that would be one of the first things I would try to resolve the issue
@klou Did you try it without increasing the memory in XOA?
@spidernin If you go to Backup > Restore, it will show you the number of existing backups for each VM.

Ok, then you should be fine since that library is installed to the script automatically. I just saw the reference to NTFS and remembered about that library.
One thing you could try is building the VM with Ubuntu instead of Debian.
@Rocky said in File Restore Not working, little red triangle:
unknown filesystem type 'ntfs'
What process did you use to build your VM? Did you install the nfs-common library?
@Rocky Registration is disabled, but I fixed it so that you can search as a guest
@Rocky Try checking over in the old XO forum
@Rocky Ok... just checking. 
Not sure on the vhdimount version and I'm not able to check my working setup ATM.
I know this issue has been discussed previously. Did you try searching the forum for any applicable discussions?
@okynnor said in How do I backup XCP-ng Configuration to migrate to a SSD?:
I would then install a brand new XCP-ng to SSD and just drop the configuration, power on and Im back in business
What about your VMs? Are they stored on your "spinners" or separately?
