mirrorios: None of the available disks support booting on this
specific system or the boot logical volume already exists on
the specified disk.
If these are new bootable disks and you
have not rebooted since configuring them. You may try
exporting LVM_HOTSWAP_BOOTDISK=1 and run this command again
to override this condition.

и вот блять че с ним делать то? :)
