I then added another disk. Added it to the LVM group, expanded the ext4 partition to then fill 2 disks. I then added another disk. Added it to the LVM group, expanded the ext4 partition to then fill 3 disks. One of the disk has now failed. Are there any tools available for ext4 that could help recover this? Note, I am a single user, not a company, so there is no money to give to a data recovery company, so I wish to try myself. Is there a mount option that will mount an ext4 partition even if there are lots of sector errors, or a missing disk. So, at least some of the files will be recoverable. Or a tool that will scan the disk for super blocks, then find inodes and then find the sector location of the files, even if they don't have filenames. Kind Regards James
