|
|
I saw somewhere a technique someone used to take a disk (or image) and turn it into a device that could be used in a data recovery attempt (and written to), but the changes were not actually made to disk, but discarded afterward (for safe non-destructive testing/recovery).
I seem to remember it being related to the SCSI system or maybe part of DM? I've searched for it, but it's hard to find unique words to describe this that don't find everything but the kitchen sink... (or a lot of VMWare non-persistent disk type stuff).
I ask because I have a RAID0 from a Windows system that was done with Intel FakeRAID (onboard) and after a BIOS update the config got corrupted so I recreated with that I thought were the same settings, but apparently not. Now I'm left with swiss cheese... so I want to use my server to reconstruct the drive as best as possible and then do a data recovery (but without knowing the settings exactly (or even what drive order) I'm left guessing and using trial and error). |

LVM has the ability to create writable snapshots. |

I would need to write to them to create LVM on top of the disks, though, wouldn't I?
I think I may have figured out what I was looking for DM Snapshot Target
I'll report back when I'm done (compiling kernel modules now)! |
