however, that's all not part of the topic "What does TRIM/discard in
RAID do"
Except - may I suggest you go back and read your very first reply to the
OP - "trim makes no sense in the raid layer". YOU said, in effect, "it's
not implemented because there's no point".
because i responded to the question "what does" and not "what would be nice"
This whole drift away from the subject was sparked by that comment -
your comment - when in fact trim DOES make a lot of sense. It's a shame
it isn't implemented
a lot of things would be nice - like people only talk about things the
know at least a little bit
in conext of RAID and your "degraded reshape of a 4 drive RAID10 to
RAID1 should be only a metadata update" i doubt that strongly
