You should try and narrow down the problem, is it always the same drive
that has that problem every time? Does it occur if you do a check on the
RAID 5 array or only when building? etc..
Assuming you're talking about the HSM violation error ... I got that
exactly once (yet) in the situation described (sometime after the
writing phase of badblocks). Nothing since and certainly not the spew
others are reporting.
Are you by any chance running quota?
My primary concern now is the second problem - seems like any access
to the raid array makes the machine unusable. I can type/edit a
command at the bash prompt normally but as soon as I hit enter it just
hangs there. If the command is trivial, say cat, I might get a result
a few minutes later.
bonnie++ results are in:

Something is definitely not right ... :-(
As in, an old array of 300GB IDE Maxtors has 4x the seq writes, bus
capped (105MB/s, plain PCI) reads and 3x the IOs. And it doesn't block
the machine. Granted, there's the crypto but on my other (non-raid)
boxes the performance impact just isn't there.
Any help appreciated, as it is the box has expensive-paperweight status.
