Hi all.
Ive got a bit
of a problem with re-importing my volume group on this system.
I was removing a few hard drives and moved it to a new
system. I vgreduced and everything to remove drives,
it seemed working okay, so I exported in preparation to move to another box.
Now, I am unable to import it again. I have plugged the
drives I removed back in, just in case, however they seem to be not related.
Im pretty new to lvm, so maybe ive missed something obvious?
Ive been googling and reading howto for a
couple of hours, ive still no solution (maybe im a noob?). Ive
seen some other vgimport related stuff, but not as
seemingly simple as this?!?
Does anybody know why vgimport is
saying I have the wrong number of drives?
Im 99% sure its wanting 4 drives, but it still isn’t liking me very
much.
Alternatively, does anybody know how to get data off this exported
vg, so I can at least not loose everything?
I noticed people were posting lots of info, so I thought I might
do the same, just to give a good idea on whats going
on

hde, hdf and hdb were going to be
removed. As you can see there they seem pretty much unrelated to the problem,
but I have plugged them back in just in case

Plus a heap of other stuff.
The “Cur PV” amount to me says my vgremoves were successful, and all I should be importing is
the 4 drives that are still active.
“vgimport
storage_group /dev/hdg
/dev/hdc /dev/hda3 /dev/hdh”
shows:
vgimport -- ERROR:
wrong number of physical volumes to import volume group "storage_group"
but:
“vgimport
storage_group /dev/hdg
/dev/hdc /dev/hda3” shows:
vgimport -- ERROR:
only 3 physical volumes of 4 given for volume group "storage_group"
and this is a bit
weird (notice the ordering of drives)
“vgimport
storage_group /dev/hdg
/dev/hdc /dev/hdh”
vgimport -- ERROR:
wrong number of physical volumes to import volume group "storage_group"
I didn’t think the ordering of the import command was
important?
any ideas
anyone on how to get my group imported>
