I had (up to 1 hour ago) a Redhat 7.3 machine kernel 2.4.20 with LVM 1.0.8 and data disks in a
lvm environment 1,5 TB of datas.
I didn't backup nothing about the LVM configuration (i know it is an error)
I had to reinstall the OS to a new version, so i did
shutdown -r now
installated Scientific Linux 3.0.4 that has inside the LVM 1.0.8 rpm revision 9
so now when i run vgscan it tells me
>vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- only found 0 of 1600 LEs for LV /dev/flat00_exp_local/exp_software (0)

My question is this
Is There a way to recover all the datas on the 3 Logical Volumes ?
If i try with vgcfgrestore it doesn't work because it try to look in /etc/lvmtab.d/ that is empty (i reinstalled the OS)
Any hint to recover the lvmtab in someway or to create one with the info needed ?
Thanks for any suggestion or hint
Claudio Soprano (please answer to my email address too, thanks in advance)
