The RAID array consists of drives that are on cheap SATA controllers
no RAID function on them.  That is why I chose to use mdadm instead of
a true RAID card.

So the errors would happen regardless if heat was an issue?

I'll wait until the reshape is done then, shutdown the machine and
re-arrange the drives before I add another drive to the array.

Thanks.

Errors are not necessarily caused by heat, probably more a controller or
firmware issue, which will present identically if you restart the reshaping
process.
Also, this kind of issues on my 3ware controller are harmless. You could
better ask this to SCSI people, but there are up to 5 retries (for EACH scsi
command) by the scsi layer after these resets happen.
Stopping the reshape is much more risky imho.
