There are two other logs you can access from the debug window. They may offer a little more information. One is: info log t -- The second one is: i l p -1 (make sure you have spaces in there).

When i was having trouble with mine, i could see the following in the logs:

01/12/2007 15:11:29 106 D SYS | RAID5Resync on array 0: 47% done
01/12/2007 15:15:48 106 D SYS | RAID5Resync on array 0: 48% done
01/12/2007 15:18:30 106 D SYS | DISK: req=0x692EDC8 dev=0xC0002 fn=1blk=0x7D6A360 sts=18
01/12/2007 15:20:09 106 D SYS | RAID5Resync on array 0: 49% done

You can see it is reporting progress then, there is some kind of disc error. In this case dev=0xC002 is telling you which drive is throwing off errors.

I had another user tell me that the hard drives generate a lot of heat when rebuilding a raid, he suggested removing the cover to allow for better cooling.

I also tried switching cables to be sure the problem didn't move around when cables were moved. It did turn out to be a bad hard drive in my case. After replacing that drive (and taking off the cover) I was able to get a successful raid 5 rebuild.
