I installed a Centos 4.x system using a lvm install across four HDDs. It is my first install using LVM. System had a power-failure and stopped booting up. A new trainee simply took out the HDDs and restarted the file-server on a fresh HDDs. Now the problemis that the four HDDs have data. But the order of the HDDs (of install....1st primary, 2nd primary etc.) is unknown. Earlier we used to boot with knoppix live cd and recover data through rsync. Knoppix is not automatically recognizing lvm partitions. My query is to ask for step by step instructions on finding & mounting my lvm partitions correctly using knoppix or installing earlier hdds one by one in the new file-server & restoring data to users. Pointers on any howtos or detailed examples of recovery would also be appreciated. With best regards. Sanjay.
