Without knowing this I will probably opt for your way: rsync data out,
starting from the smallest and most important stuff...

I had another thought:
If I take the computer offline, boot with a livecd (one of the worst
messes here is that the root filesystem is also in that array), run the
raid6 array in READONLY MODE and maybe without spares, then I start a
check (scrub) ...
If drives are kicked I can probably reasseble --force the array and it's
like nothing happened, right?
Since it was mounted readonly I think it would be clean...
Only problem would be if 1 or more drives definitively die during the
procedure, but I hope this is unlikely...
If less than 3 drives die I can still reassemble --force, and take the
data out (at least SOME data, then if it degrades, reassemble again and
try to get out data from another location...)
Do you agree?
I am starting to think that during the procedure for taking the data out
and/or attempt first scrubbing the main problem are write accesses to
the array, because if rebuild starts on a spare and then fails again and
then there were writes in the middle... I think I end up doomed.
Probably even reassemble --force would refuse to work on me. What do you
think?
Thank you
