[linux-lvm] hard drive crash info please

[Kai Iskratsch]

hi

you need lvm2 to  activate a partial volume group. if you have a backup 
of your vgcfg  then you may restore your config to a new harddisk with 
the lvm1 tools.
i had no actual vgcfgbackup so i needed to upgrade to lvm2 to activate 
the partial vg and make a backup of all partitions that were not 
affected by the crashed harddisk. then i used the vgcfgbackup on the 
partial vg and edited the meadata from the backup (lvm2 saves the backup 
data in human readable form) that all missing segments are put on the 
replacement disc. after i restored the backup everything worked again 
and i lost only the data which was on the bad disk.
