[SOLVED] Resize virtual disk that is oddly sized to a rounded size

[nightowl]

We have an imported virtual disk from a VMware system that was oddly sized (specifically 2147525591KiB).

It appears this causes an error when performing a storage migration (storage migration failed: block job (mirror) error: drive-virtio1: 'mirror' has been cancelled). Or at least, it appears that this is likely the issue. It looks like disks must be rounded to 4MiB chunks in size?

In any case, I was hoping to be able to resize the disk in KiB, but Proxmox's interface only allows for 1GiB increments. Is there a workaround to this to allow resizing in KiB?

Our alternative solution is to create a new virtual disk and use CloneZilla to copy the virtual disk, but thought there might be a way to avoid this.

Would find it strange if this were the case, but not ruling it out either.

You could try using the shell commands to resize it. The example might be including G, but maybe M or K works too (not tested, so maybe try it out with a test-disk first)

@sw-omit - Great ideas! I actually hadn't tried using M or K - thinking that it was limited to only GiB, and you are correct - this works fine. I feel kinda dumb for not thinking of this!

An example to add 512KiB to a disk:
qm disk resize <vmid> virtio1 +512K

Or - you can specify the absolute dise of a disk and it will compute the difference and add the respective amount to the disk. This is what I used!
qm disk resize <vmid> virtio1 2060G

And the storage migration works perfectly now.

Thanks again!

You're welcome and good tip for the absolute size.
