Due to a disk failure I'm having to do a full raid1 reconstruct on one
of my systems and the performance seems much slower than last time I did
it on this system.
I'm seeing a write speed of 7MB/s which means my 2TB reconstruct is
going to take 72+hours! Last time I did it it took about 3 hours if I'm
remembering correctly.
The filesystem level performance of the raid when its working is a lot
faster than this this speed.
