Hello,

I've done

after being sure to restore the metadata I have

pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/hdg1" of VG "bigspace" [74.47 GB / 768 MB free]

=> after the vgscan the echo -ne "bigspace\0" > /etc/lvmtab is gone gone
again....

[root@ment root]# lvscan
lvscan -- ERROR: VGDA in kernel and lvmtab are NOT consistent; please

after doing the vgscan, I get

pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/hdg1"  is associated to unknown VG
"bigspace" (run vgscan)
pvscan -- inactive PV "/dev/hde1"  is associated to unknown VG

again.


the /dev/bigspace/bigspace1 doesn't exists, so I can't mount.

should I recreate bigspace and force an import ?

I 've alse rebooted once after the vgchange -ay, but he also didn't find
the bigspace.

thanx again for your help!!

kind regards,
Thomas.
