After doing some more research throughout the day, I've tried a few solutions for other somewhat similar problems, all to no avail. Fortunately, I still have the old system drive with its /etc/lvm* data, so I plugged it back in hoping to resurrect my data. >From this message: http://www.somelist.com/mails/403762/ I tried a similar solution: [root@terminus root]# cp /etc/lvmconf/vg_data.conf /etc/lvmtab.d/vg_data [root@terminus root]# echo -ne "vg_data\0" >> /etc/lvmtab [root@terminus root]# vgchange -ay vg_data vgchange -- ERROR: physical volume "/dev/md0" of volume group "vg_data" is inconsistent vgchange -- run vgscan [root@terminus root]# Of course, running vgscan just results in the bogus "vg_wbl" being detected. Then I tried vgcfgrestore, again without any luck: [root@terminus root]# vgcfgrestore -l -n vg_data vgcfgrestore -- INFO: using backup file "/etc/lvmconf/vg_data.conf" --- Volume group --- VG Name vg_data VG Access read/write VG Status NOT available/resizable VG # 1 MAX LV 256 Cur LV 6 Open LV 0 MAX LV Size 2 TB Max PV 256 Cur PV 1 Act PV 1 VG Size 447.09 GB PE Size 32 MB Total PE 14307 Alloc PE / Size 11862 / 370.69 GB Free PE / Size 2445 / 76.41 GB VG UUID HKLIZ7-72l6-OjsA-ujH0-qpMz-tDi7-1R18jZ [root@terminus root]# vgcfgrestore -t -n vg_data /dev/md0 vgcfgrestore -- INFO: using backup file "/etc/lvmconf/vg_data.conf" vgcfgrestore -- backup of volume group "vg_data" is consistent vgcfgrestore -- test run for volume group "vg_data" end [root@terminus root]# vgcfgrestore -n vg_data /dev/md0 vgcfgrestore -- INFO: using backup file "/etc/lvmconf/vg_data.conf" vgcfgrestore -- physical volume "/dev/md0" belongs to volume group "vg_wbl" [root@terminus root]# I am sure the data on /dev/md0 is undamaged, I just need to get the appropriate LVM metadata back onto it to make it accessible. Is there any way to "force" vfcfgrestore to write to /dev/md0 ? If I "remove" it from the VG "vg_wbl" and then try vgcfgrestore, will that work ? Will running "pvcreate" possibly allow the vgcfgrestore to work ? Will that damage any of the non-LVM structures on the disk ? Also, does anyone have any theories on how this might have happened, so I don't inadvertently do it again the next time I want to reinstall this system ?
