I am afraid the filesystem right now is really damaged regardless of it's state upon the unexpected cable failure because I tried some dangerous options after read-only restore/recovery methods all failed (including zero-log, followed by init-csum-tree and even chunk-recovery -> all of them just spit out several kind of errors which suggested they probably didn't even write anything to the disks before they decided that they already failed but they only caused more harm than good if they did write something).
Actually, I almost got rid of this data myself intentionally when my new set of drives arrived. I was considering if I should simply start from scratch (may be reviewing and might be saving my "scratchpad" portion of the data but nothing really irreplaceable and/or valuable) but I thought it's a good idea to test the "device replace" function in real life. Even though the replace operation seemed to be successful I am beginning to wonder if it wasn't really.
