nik_xЛучше было бы, если дамп сделать...
Но всё возможно:)
Начни с lvscan.
что за дамп ?
дамп чего ?
dd if=/dev/sdb ....................... of=/dev/НОВЫЙ ДИСК ?
имена логических групп и томов не поменяются - смысл?
посему начал с pvs
lvs
vgs
lvdisplay
pvdisplay
vgdisplay
pvscan
vgscan
......................
Sleeping Daemon
vgchange -ay
lvdisplay /*Для посмотреть какие логические группы есть*/
mount .....
vgchange -ay
понадобится только после переименовывания volume group
а до того времени скорее
vgchange -an
но мне не понадобилось
покажу как сделать - заодно себе помечу - спасибо всем ))))
сначала воткнул диск в FC6
