Re: [linux-lvm] Hard disk failure, restore problem



Hello,

I've done

> o identify your actual metadata backup (say, bigspace.conf)

>
> o echo -ne "bigspace\0" > /etc/lvmtab

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
run vgscan

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

pvscan -- total: 7 [708 GB] / in use: 7 [708 GB] / in no VG: 0 [0]

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.
