I guess I should have mentioned the results from lv* commands I tried (lvdiskscan appears not to be a Fedora command). I'm afraid to do anything with lvcreate because I don't want to step on what's there--unless I am misunderstanding how things work. It looks to me like the volume group is there, but the system can't find or doesn't know the label. I wonder how to tell it that the label was LogVol00.<br><br>Here are some results:<br><br>[root@mythserver ~]# lvchange -vvvay /dev/VolGroup00/LogVol00<br> Processing: lvchange -vvvay /dev/VolGroup00/LogVol00<br> O_DIRECT will be used<br> Setting

I was, at last, able to solve this problem. I was right all along...the data was there. So when I started experimenting with the archive files associated with LVM, I stumbled on success. Someone suggested "vgcfgrestore" might work; however, I had to use trial & error with the -t (test) parameter in order to figure this out. By that I mean reading the LVM HowTo and various man pages did not clarify much for me. So here are the steps that I
took:<br>--------------------------------------------------------<br>[root@mythserver lvm]# vgcfgrestore -tf /etc/lvm/archive/VolGroup00_00000.vg<br> Test mode: Metadata will NOT be updated.<br> Please specify a *single* volume group to restore.<br>[root@mythserver lvm]# vgcfgrestore -tf /etc/lvm/archive/VolGroup00_00000.vg Vol<br>Group00<br> Test mode: Metadata will NOT be updated.<br> Restored volume group VolGroup00<br>[root@mythserver lvm]# vgcfgrestore -tvf /etc/lvm/archive/VolGroup00_00000.vg Vo<br>lGroup00<br> Test mode: Metadata will NOT be updated.<br> Restored volume group VolGroup00<br> Test mode: Wiping internal cache<br> Wiping internal VG cache<br>[root@mythserver lvm]# vgcfgrestore -tvvf /etc/lvm/archive/VolGroup00_00000.vg V<br>olGroup00<br> Test mode: Metadata will NOT be updated.<br> Setting global/locking_type to
