In parted you're supposed to be able to delete a partition, make a new one, and your data will still be there. It's gone. Nothing, not even testdisk is finding the partition. If I do the same stuff to a partition at the beginning of the disk, everything is fine, but this one starts 4221GB out. What am I to do?
Reply: Every instructional bit says to delete the partition, make a bigger one, and use the e2fsprogs stuff to resize it. As I said, on a test partition at the beginning of the disk, it works just fine. It's not a single disk, it's a RAID6 array, so there's no worry for it just dying. Most people can't afford to build a second machine to hold another 8 TB of data.
Reply2: It doesn't change the fact that a partition at the beginning of the disk, I can delete, make a new partition, and it will still be there.
Reply3: The instructions that say to do this are all over the place, so I'm not going to link to any. I had to use existing hardware to build this server. I don't have a few thousand dollars to build another box with another RAID card, the same number of drives, and the appropriate case. I still want to know why when I delete a partition situated at the beginning and recreate it, it's just fine, but anything in the middle of the disk dies when I do this. I tried testdisk. It finds all kinds of crap that doesn't make any logical sense, and nothing relating to the partition that existed. PhotoRec finds stuff, but does a horrible job, and most files are aligned to 2MB. I don't get why if the data is there and was never overwritten, it can't be recovered. I never had this much trouble with NTFS.
