[Solved]LVM metadata recovery

Hi everyone,

I'm a huge idiot :oops:

I decided to convert my slackware fileserver to arch (since it has much better package management). On my fileserver I was using lvm and when I put arch over slack it didn't even cross my mind to backup my lvm config files. Now on arch I have lvm running and I can see all my drives and volumes, but when I try to activate it I get:

Volume group vg00 metadata is inconsistent
Volume group for uuid not found: fhRVK5ZTwTOdTQpgF8oyAESEj8LYNRJy1P1jjdkNCV1WhYwfv9rxpnExXvNu13T6
0 logical volume(s) in volume group "vg00" now active

If I run pvscan I get:
PV /dev/hda3   VG vg00   lvm2 [128.54 GB / 0    free]
PV /dev/hdd1   VG vg00   lvm2 [74.52 GB / 0    free]
PV /dev/hdb1   VG vg00   lvm2 [186.30 GB / 29.36 GB free]
Total: 3 [389.36 GB] / in use: 3 [389.36 GB] / in no VG: 0 [0   ]

and vgscan returns:
Reading all physical volumes.  This may take a while...
Found volume group "vg00" using metadata type lvm2

What are my options if any?

Thanks,
Alex

Re: [Solved]LVM metadata recovery

I got a solution to this from a nice person on the lvm mailing list, maybe it will help someone:

I've had this problem as well: The volume group existed and all of its
PVs existed, but the volume group wanted different UUIDs than the PVs
had.

The solution is kind of scary but seems to work, I got it from a Fedora
discussion site, where someone said they had this problem but just
backed up & resotred the config:

$ vgcfgbackup -f cfg_backup vg00
$ vgcfgrestore -f cfg_backup vg00
