I think that gave a little breakthrough :-)
First of all - as murphys law suggests, I don't have a backup to use with
vgcfgrestore - but with the tool I did manage to recreate both /etc/lvmtab
and /etc/lvmtab.d :
Vault:/home/ultra# vgcfgrestore -n site_vg /dev/hda8
vgcfgrestore -- VGDA for "site_vg" successfully restored to physical volume
"/dev/hda8"
Vault:/home/ultra# vgcfgrestore -n site_vg /dev/hdb1
vgcfgrestore -- VGDA for "site_vg" successfully restored to physical volume
"/dev/hdb1"
the only problem is that they are both really empty, so with vgscan I find
nothing :
Vault:/etc# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- no volume groups found
But to my big relief, the data is still present on the physical drives :
Vault:/etc# pvdisplay /dev/hda8
--- Physical volume ---
PV Name /dev/hda8
VG Name site_vg
PV Size 14.1 GB / NOT usable 1.21 MB [LVM: 135 KB]

Thanks for the help so far Andreas, but where do I go from here ?
Thanks in advance
