It looks like your home lv is split into two segments, one that is 3 GB long and at the start of the pv, and another segment that is 43 GB long and elsewhere on the disk. Did you create the home lv first only 3 GB in size, then extend it later? The second segment starts at extent 0, which is at sector 384, and is 768 4 MB segments long, or 768 x 4096 x 2 = 6291456 sectors. The first segment starts at extent 5376, which is at sector 5376 x 4096 x 2 + 384 = 44040576 and is 11008 extents or 90177536 sectors long. These are all relative to the physical volume, which looks like it was in /dev/sda7. If you overwrite the partition table then you will need to figure out where that partition started. > In the lvm backup file, I don't know what is the value "pe_start" in pv0 > section. What is this value ? pe_start is the sector where the first physical extent is. _______________________________________________ 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/
