LVM -- Mistake - please HELP

[johnthomas]

I had to reinstall, I have two raid 5 arrays. both belonging to /dev/vg00 and only 1 lvol in vg00 using 100% of the extents in vg00. after my reinstall I screwed up and did ---

I meant to do a vgimport but instead did
vgcreate /dev/vg00 /dev/md0 /dev/md1

not sure what i was thinking, but now i have a vg with almost 5TB free - not good being that it was only about 15% free prior to the reinstall.

ANY IDEAS on how I can get me lvol back would be much appreciated.

BTW I dont have a vgoo backup conf to do a vgcfgrestore either.

thanx

Give this a read.http://www.barryodonovan.com/index.p...8/lvm-recovery
From what I could understand, he removed each lvm part,
then created pv, vg
extracted the lvm/backup to a (readable place.)
then did the vgrestore -f (which I guess can fine the true LV size.

This is based on the fact that the data has not changed and every LVM piece does not affect the data area.
But "dont have a vgoo backup conf to do a vgcfgrestore" is not good, so this method makes one.

Run at your own risk,no guarantees, non-refundable, all parts are yours to keep, good luck.

The new install is not on the raid so how would they be in the /etc/lvm/archive?

Or maybe he's not telling the whole story.

thanx Slow Jet, but the guy did have a backup copy of his vg config from his old drive.
I was in the process of backing up my system when the root disk failed.
I just got the system configured how I wanted and migrated all my data to my raid 5.
then I shot my self in the foot
