Ooops, just saw it. /dev/sdd3 apparently has the wrong size.

As to why this is so, it's a mystery.

I'll investigate further into this. (Since this is the office's gateway,
I'll take some time to respond eventually. No server = no Internet :oD)

Hi Niki,

in fact all of the sdX3 partitions are of size 76.4G. Maybe they were created by
the installer as part of a partition scheme and you forget to resize them when
removing other partitions from the scheme? Anyway, it should be fine if you
recreate the partitions with the right size and then recreate the array.

actually, it looks like problem is with /dev/md3, not just /dev/sdd3, as
_all_ drives are wrong in their 3rd partition.
