Finally got to a disk that has errors but now I don't know what to do. This is what was displayed:
reiserfsck 3.6.24

block 14909443: The level of the node (56336) is not correct, (1) expected
the problem in the internal node occured (14909443), whole subtree is skipped
vpf-10640: The on-disk and the correct bitmaps differs.
I understand that the --rebuild-tree command will likely result in lost data to some degree. Am I better off to replace the drive (assuming the Parity drive is doing it's job and ZERO data will be lost), or has this corruption destroyed the data even with a Parity drive?
I don't want to run the command and risk losing data if all I have to do is swap in a new drive for that one...and not lose anything. Or am I misinterpreting that incorrectly?
Thanks again for all the help, it is greatly appreciated!
