I had a temporary disk failure on a software RAID5 device yesterday containing a volume group "hekvg". I was able to bring my RAID5 online using mdadm --assemble /dev/md0 --force, but now my LVM volume group refuses to vary on. Here are my errors: lnxsrv2:root> vgscan vgscan -- reading all physical volumes (this may take a while...) vgscan -- found active volume group "vg00" vgscan -- ERROR "pv_read_pe(): read" can't get data of volume group "hekvg" from physical volume(s) vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume groups lnxsrv2:root> vgimport /dev/hekvg /dev/md0 vgimport -- ERROR "pv_read(): multiple device" reading physical volume "/dev/md0" lnxsrv2:root> pvcreate -ff /dev/md0 pvcreate -- really INITIALIZE physical volume "/dev/md0" of volume group "hekvg" [y/n]? y pvcreate -- WARNING: forcing physical volume creation on "/dev/md0" of volume group "hekvg" pvcreate -- physical volume "/dev/md0" successfully created lnxsrv2:root> vgcfgrestore -n hekvg -f /etc/lvmconf/hekvg.conf /dev/md0 vgcfgrestore -- ERROR "pv_write_pe(): write" storing VGDA of "hekvg" on disks lnxsrv2:root> vgchange -a y /dev/hekvg vgchange -- volume group "hekvg" does not exist lnxsrv2:root> pvdisplay -v /dev/md0 --- Physical volume --- PV Name /dev/md0 VG Name hekvg PV Size 949.58 GB [1991416320 secs] / NOT usable 5.06 MB [LVM: 1.05 MB] PV# 1 PV Status available Allocatable yes (but full) Cur LV 8 PE Size (KByte) 4096 Total PE 243091 Free PE 0 Allocated PE 243091 PV UUID MAfau0-qK8F-oNAg-gfH9-dw7s-lU3a-PftQTo pvdisplay -- ERROR "pv_read_pe(): read" reading physical extent information This is a production server which I need to get back online ASAP.
