now i can not mount original disk it gives me this error
root@pve:~# mount /dev/mapper/origin-disk /mnt6 mount: /mnt6: wrong fs type, bad option, bad superblock on /dev/mapper/origin-disk, missing codepage or helper program, or other error.
the problem is disk usage show bigger than disk size too!

The harddisk (69 GB / 64 GiB) seems too small! (< 248 GB / 231 GiB)
Check the harddisk size: HD jumper settings, BIOS detection...
The following partitions can't be recovered:

i try to recover by testdisk both /dev/sdb2 and /dev/mapper/origin-disk here is the output
but i did not write into yet is there any solution?
