LVM screw up after reinstall

[gr0ver]

I had to reinstall, I have two raid 5 arrays. both belonging to /dev/vg01 and only 1 lvol in vg00 using 100% of the extents in vg01. after my reinstall I screwed up and did ---

vgcreate /dev/vg01 /dev/md0 /dev/md1

not sure what i was thinking, but now i have a vg with no lvols and 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 vg01 backup conf to do a vgcfgrestore either.


I was in the process of backing up my system when my root disk failed ( only
2 months old )
/home and /usr are the only things did get backed up.
i know vg config files are in /etc/lvm is there a chance there is anything in
/usr that might help.
if I had /etc i could get the conf files and do a vgcfgrestore and be in good
shape from there.

There has to be a way to rebuild / repair / recover the VGDRA on the disk.
the data isnt lost, just vgdra is now hosed.
can a conf file be made that i could use for vgcfgrestore.

When I created the VG orginally it was on /dev/md0 and used 100% of it.

I only had 1 lvol
my conf is below - there has to be a way to add the lvol info to it, then i
could just run vgcfgrestore with it.

I know 100% for a
fact I had only one lvol and 0 extents free and /dev/md0 was first then I
extended it to /dev/md1
I then created /dev/md1 and added it to the vg, then did an lvextend of the
single lvol to use all of /dev/md1

my conf is below - there has to be a way to add the lvol info to it, then i
could just run vgcfgrestore with it.
oh it was named vg01 not vg00 like I originally thought. I know 100% for a
fact I had only one lvol and 0 extents free and /dev/md0 was first then I
extended it to /dev/md1

Those who think Windows is the answer -
Dont understand the question

[b2bwild]

You havnt created the logical volume

to create it, command is lvcreate

# lvcreate -L <size> -n <name> vg01

(<size>=size i.e. 100G)(<name>=name of lv)

then format /dev/vgo01/<name>
with filesystem
