LVM просмотр содержимого дисков
На старом сервере полетела система (Red Hat Linux 4). Насколько я понял там было 4 диска SCSI 36Гб и из 3х из этих дисков был собран один логический диск lvm. Один из дисков умер, на одном послетали разделы (из-за этого и linux слетел). В итоге от lvm остался только один живой нормальный диск (/dev/sdc1)
Вообщем в срочном порядке переустановили RHEL4 на новый диск, попытались восстановить разделы на проблемном диске.
В итоге чистая работающая система, бэкапа /etc/lvm нет, возможности добавлять/убавлять чистых дисков нет.

Подскажите, как просто посмотреть структуру каталогов на выживших дисках, может и не стоит заморачиваться с восстановлением, если нужных данных не осталось там.
Вот ещё вывод fdisk -l для четырёх дисков:

Опыта в данном деле практически нет, экспериментировать и снимать диски на рабочем сервере возможности нет :(
