Hi all,
Does anyone know if it's possible to recover an LVM partition from a drive that was fdisked? I accidently fdisk'd the wrong drive (had to fdisk a lot of 160GB drivers from old servers and one still has important data on that client now wants) by running fdisk /dev/sdc & deleting the partitions. The drive is still in a another machine and hasn't been rebooted yet, but there's no no partition on it.

re-create the original partition table, which is just a map, as long as you haven't formatted or overwritten data everything should still be there
Also suggest if your not already doing it set your LVm partitons to type 8e so it's obvious they are LVM
[root@dc1-mysql001b:~]# fdisk -l /dev/sdc
Disk /dev/sdc: 2197.9 GB, 2197949513728 bytes 255 heads, 63 sectors/track, 267218 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System /dev/sdc1 1 267218 2146428553+ 8e Linux LVM

And if you don't exactly remember how the partitions where set up, you could try parted with the rescue command. It will search the raw disk for signatures that could be the start of a partition.
