Unable to move volume (Root Disk) / Restore backup on main SSD drive

[Asiier]

Hello everybody!
I'm trying to move on of my Container to my main storage drive (SSD) from my other drive (HDD using ZFS).
I installed (restored backup) by error this Container on my HDD but now I'd like move it back to my SSD so it's performs faster.

The problem is whenever I try to restore the backup I get the following errors:

The bootdrive is not even half full but I tried to manually restore the backup assigning more space on the drive. In that case it would create, or rather, restore the Container but I'm unable to start it and no error are thrown.

pct restore 115 /path/to/backup --storage local-lvm --rootfs local-lvm:3,size=3G --force

If I restore it on the HHD everything works well, but If I try to move the volume to my SSD I get the following error:

Thank you in advance!

Can you post the output of 'df -h' as well as 'zfs list' (if using ZFS) or 'lvs -a' (if using LVM)?

Sure!
I use ZFS for my 6 TB HDD and LVM for my 256 GB SSD and another 1 TB HDD

How are you copying or restoring the backups? Can you post the exact command or GUI path (screenshots?) you are using? It certainly seems confusing, the error is definitely an "out-of-disk-space" one, but I don't see a disk where that would be the case...

Also, what's in your /etc/pve/storage.cfg?

The bootdrive is not even half full but I tried to manually restore the backup assigning more space on the drive. In that case it would create, or rather, restore the Container but I'm unable to start it and no error are thrown.

I'm a bit confused by this part. What exactly did you attempt here?
