помогите восстановить lvm

Имеется машина с 2-мя хардами и корнем на lvm (система - mandriva 2009.0)

root@ubuntu:~# cat /proc/partitions
major minor #blocks name

8 0 488386584 sda
8 1 305203 sda1
8 2 1 sda2
8 5 488078766 sda5
8 16 488386584 sdb
8 17 1 sdb1
8 21 488383969 sdb5
7 0 691636 loop0

разделы sda5 и sdb5 в lvm группе komp.

было сделано

pvmove /dev/sdb5 - прошло успешно
pvremove /dev/sdb5 - предложило запустить себя с -ff
pvremove /dev/sdb5 -ff - привело к ошибке следующего содержания:

Couldn't find device with uuid '1WjUR5-DB6e-eXN0-BERs-X8bm-j3qK-EMg2Rc'.

Система не загружается, т.к. корень на ЛВМ. Сейчас сижу на лайвСД Убунту 8.10

Кто-нибудь сталкивался с подобным? В чём корень зла?) Как бороться? Про ошибки в ДНК занаю, можно не напоминать)
