Hello, First, sorry for my english. The other day, I wanted to create a multi-iso usb (for install- party) but I stupidly copied the image on my main hard drive. When I have seen my error, I have stop the copy and run "cat /proc/partitions" to make a backup of my partition table. But the system was crash before. I have reboot to a liveCD and make a copy of my disk on an other disk. I have run testdisk and gpart on this image without success. So I have make a bash script with dd and grep to find some file or some special block. With this script, I have found my last lvm backup text file ( http://pastebin.com/TTSnpr47 ) I want to know if I can make an image file of my home LV with this file and how to calculate the start/end sector (on the disk) of my home LV. dd if=sda.img of=home.img bs=512 count=size_of_home_part1 skip=start_sector_of_home_LV I think that size_of_home_part1 is 11008*8192 but I want to know how to calculate start_sector_of_home_LV. How to calculate this value ? In the lvm backup file, I don't know what is the value "pe_start" in pv0 section. What is this value ? thanks for your help. Some more info: # hdparm -g /dev/sda /dev/sda: geometry = 14593/255/63, sectors = 234441648, start = 0 My partition table before the crash. /dev/sda1 /boot ~200Mo /dev/sda2 /boot2 ~200Mo /dev/sda3 swap ~1Go /dev/sda4 /dev/sda5 PV ~107Go End of disk _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
