Did you fsck -f the array before re-sizing the filesystem ?
What does fsck -f show on (the unmounted) filesystem now ?

Ough. Bad bad.

Possibly raidreconf. I am very suspicious about the spare-disk anomaly
that you saw - it is possible that raidreconf did "the bad thing" with
your array.
It is also possible that you have hardware errors, bad cabling, bad
disk, etc. Anything suspicious in dmesg ?
It is really important to run fsck -f on arrays after running raidreconf
and before re-sizing the filesystem. For this reason - tracking of
when/where errors occurred. Of course, it is a little late for you to
be told this now - sorry. I should add this note to the raidreconf
output after successful reconfiguration.
I will try to see if I can dig out a SCSI crontroller from the crap-heap
here at work, then I will see if I can reproduce the spare-disk error.
It is entirely possible that that is the reason for the screwup.
