I lost all of my data (8 TB) which I collected over the past few years yesterday because I made some seriuos mistakes during the remounting of my LVM. I run a XenServer5.6 installation with additional 4 harddisks for data storage. An LVM over those 4 HDDs was used to store all of my data. Yesterday, I reinstalled XenServer and wanted to mount my old Harddrives and add the LVM. I run
xe sr-create [...]
for all disks (/dev/sdb .. /dev/sde), but that was totally wrong. This command deletes the old LVM on the disks and created an new, empty lvm on every single disk with no partitions. No i got 4 empty harddrives :(
Is it possible to recover some data from that lost LVM volumes? I have no clue how to do it because i deleted all informations about the old LVM. Is there a way to access the files insed that old lvm directly?
