Good evening! I was recently given the task of trying to salvage files from a 1.5TB harddrive that was accidentally formatted and/or repartitioned. Normally I would do a 1:1 copy of the whole drive to a file and operate on that, but I simply do not have that much room this time. Ideally I would like to create a writable snapshot in the same way as I do with my LVM volumes, storing the changes in a smaller file or in another block device so that I can experiment freely without worrying about destroying anything else on the drive. Is this possible (probably) and easy (probably not?) with any device mapper tools? I'm not really sure where I should begin looking, because dmsetup is probably pretty low-level. Thanks for any pointers and ideas. // Anders -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
