[pve-devel] [PATCH qemu-server 9/9] add check to resize disk if current size could not be determined

[Oguz Bektas]

From: Tim Marx <t.marx at proxmox.com>

This check ensures that disks aren't unintentionally shrunken, if the
size is zero due to an underlying problem.

(cherry picked from commit f8b829aabae2fdc8bdd9ace741bbef3598b892f2)
