After removing some logical volumes (backup,etc) and extending home logical volume, data in the whole volume group (vg1) has become corrupted: Root logical volume is mounted at boot time, but am unable to mount any other logical volumes in that volume group (var,home etc) after reboot. pvscan displays : PV segment VG free_count mismatch: 0 != 4294966485 Internal error: PV segments corrupted in vg1. No matching physical volumes found vgdisplay, vgchange,vgscan display similiar message. Using 2 IDE drives, with 2 meta disks on each (mirrored across the drives). 1 meta disk contains boot 1 meta disk contains LVM - 1 volume group, logical volumes for root,swap,var,usr,home vgcfgrestore fails. /etc/lvm/backup/vg1 contains (english) description of last known state of the logical volumes. /etc/lvmconf/vg1.conf is a binary file (may be out of date) /etc/lvmtab.d/vg1 appears to be the same binary file above (may be out of date) System is Debian Unstable, running lvm2,udev,device mapper, kernel 2.6.8 compiled from Debian source. System appeared stable for 1 week after lvm changes, but failed on reboot. 1. What command can be used to recreate the vg1.conf binary file from the english description backup? (vg1.conf modification date is older than changes) 2. What is the VG free count and how can it be reset to 0? 3. What other tools available to fix broken lvm.
