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. _______________________________________________ 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/
