[linux-lvm] problems importing non-exported VG

[linux-lvm] problems importing non-exported VG

[Todd Underwood]

folx,

after an upgrade during which i moved from a root LVM system to a non-root
LVM system and my /etc/lvm* files/directories were lost, i find i'm unable
to re-import data from a previously existing volume group and i'm not even
sure what the right steps are.

the previous vg name was rootvg.

appended is some info about the pvs.  i had thought that i could re-create
rootvg from /dev/hdc1 /dev/hdc2 and /dev/hdc3 that previously held it, but
that seems not to work.  the vg was created with 0.9.1-beta7.  any
suggestions would be greatfully appreciated.

Did you try running vgscan?  Grep doesn't show it in your
mail, so I ask that 'stupid' question.  No guarantee that
it'll work, though

wolfgang, all,

yep, vgscan finds no volume groups on the system. sigh.  i guess i really
need a backup of /etc/lvm*, which is on the lv.  sigh again.

You did not export the vg, right?  So there would be no use
to use "vgimport rootvg /dev/hdc1 /dev/hdc2 /dev/hdc3"...

Hmmm.
