[linux-lvm] Re: PV segments corrupted in vg1 : LVM corrupted



Noticed that pvdisplay works, and looks bad (0 Allocated PE)
 --- Physical volume ---
  PV Name               /dev/md1
  VG Name               vg1
  PV Size               25.40 GB / not usable 59.38 MB
  Allocatable           yes
  PE Size (KByte)       32768
  Total PE              811
  Free PE               811
  Allocated PE          0
  PV UUID               EW1NJk-11h8-GVOX-zmcn-2l3V-fg0G-RWNyod

also mdadm cannot find an md superblock(not sure what this means):

mdadm --detail --query /dev/md1
/dev/md1: 25.40GiB raid1 2 devices, 0 spares. Use mdadm --detail for
more detail.
/dev/md1: No md super block found, not an md component.

lvmdiskscan looks ok.
lvm dumpconfig looks ok. 

Re-install of OS looks likely, just dont know why things got corrupted.  
Dont know where the pv volume information is stored.
