I would like to ask your opinion about my theory, how to fix my broken LVM without risking any data loss.
I use Archlinux at home. I just love this distro, even it gives me a lots of work (particularly after system updates).
Basic system spec:
AMD FX(tm)-6100 Six-Core Processor
2x8GB Corsair DDR3
ASRock 970 Extreme3
3 x Seagate Constellation ES (SATA 6Gb/s) in sw RAID5, LVM on the top of the array
1 x Western Digital Caviar Blue (SATA 6Gb/s) for System
1 x Western Digital Caviar Blue (SATA 6Gb/s) for media(music/films/etc.)
I use this machine for work and for fun. I run several VMs in Virtualbox 4.x and playing World of Warcraft sometimes.
My main storage is on the RAID5 array (/dev/md127p1). I have created one VolumeGroup here(vg00) which contains one LogicalVolume (storage). I have a lots of install media here. Also I have some rare Oracle install stuffs here too(9/10g DB/AS/Portal, patches,repca and other stuffs) which I don't want to lose. I need them to my work.
After a full system update and reboot my little Archlinux was broken. I have fixed most of the problems, now I'm able to boot and my new Gnome3 is also working, however the system can't see the LogicalVolume.
After installing one extra hdd ( 3TB WD ) I will be able to clone all the bits of the RAID5 array, which contains(?) the LVM metadata too using dd. Hacking a little the lvm backup file (change the pv device name and id from /dev/md127p1 to the new disk, /dev/sdf1 or something) I may will be able to restore the VolumeGroup's metadata on the 3TB WD hdd. So if I scr*w things up during the restore process, I wont purge all my datas on the original RAID/LVM.
I am having trouble with LVM and one of my physical volumes.

I was trying to set up LVM across two disks (not containing the OS or Home).
First I created the initial Physical Volume, the Volume Group, and the Logical volume, and everything seemed fine. The... (2 Replies)

I would really appreciate help on recovering some data.
I have a RAID1 array under /dev/md0 composed of devices /dev/sdb and /dev/sdc. I had lvm on the raid with 3 lv, the last of which was a snapshot partition.
My / is on /dev/sda. Recently, I reinstalled the system (Debian lenny)... (7 Replies)
i have a query regarding the size of the LVM header. Since the LVM header of a bootable disk is always 2912KB. The header size of a non bootable disk is not fixed. In Bootable disk after the LVM header (2912 KB=5824 sectors)the user data starts or we can say LV extents starts.
