unallocated space after vm disk shrunk

[ChrisSlashNull]

Hello,

I want to shrink the size of a vm from 100G to 30G.

• I booted the vm into gparted and resized the partition to 29G
• I shutdown the vm
• ran "zfs set volsize=30G rpool/data/vm-201-disk-0" to leave a little overhead
• ran "qm rescan" and got the message that the disk-0 has no 30G instead of 100G

The vm boots (grub is waiting a very long time before letting me login) normal.


When I boot into gparted again I get a few messages that there are no partitions outside of a disk allowed and it displayes me 70G unallocated (the size I want to shrink).



Can you help me with this problem?

Thanks
Chris

It looks like the swap partition is not being found. Make sure that you have a swap partition on the resized disk. You can create one with gparted.
In your VM check the new UUID of the swap partition with blkid
Then replace the old swap UUID in /etc/fstab with the new one.
Finally run update-initramfs -u

This should resolve the problems.

Thanks @fschauer I will try your steps.
But why displays gparted the 70G I removed as unallocated? It should be removed from the VM?
