Hello,
I am trying to move a VM from one node to another inside the the same Proxmox VE cluster.
Storage is rather large but the destination node has enough disk capacity.
I am getting an error when I try to do an online migration:
If I run a lsblk -b inside of the VM I get a disk size of 2903784816640.
However, Proxmox reports the size of the hard disk incorrectly (scsi0: HDD:vm-101-disk-0,cache=writethrough,size=2902710697329)
While trying to change the hard disk configuration (from no cache to write through cache) I noticed the size is automatically updated to 2769265M - which is the same that I got with lsblk -b command in the VM.
After power cycling the VM and the settings updated, tried running the live migration once again but I got the error log below:
This time I got a message stating that the disk size was reverted back to the incorrect value of 2902710697329, and of course this is not a multiple of the block size so the migration fails once again.
Does anyone have any suggestions as to what I should try next?
I am using pve-manager/6.1-8/806edfe1 (running kernel: 5.3.18-3-pve)
Best regards,
Nuno
