I have a problem using an Easyraid (16 bays configured for raid 5 - model
INDY 2600) with 1.6.1 (using an adaptec 29160 as the hba).
I am accessing the easyraid from two machines each with 29160s (two raid
sets one for each pc).

Since each raid set is > 1TB I have had to split it into two slices (pity
about ufs2 not being available).
The two slices are each slice 0 (sd0 = capacity 636 000 MBytes)  and slice 1
(sd1 = capacity 600 000 MBytes).

When considering one PC at a time the output from disklabelling /dev/sd0
indicated the total number of sectors to be 2147483647 - this is clearly
wrong. I wrote a code fragment that uses an ioctl (DIOCGDINFO) which not
unexpectedly confirms the same result (attached result below). Doesn't
disklabel use the same ioctl?

The output from the kernel "dmesg" file displays the total sector size of
sd0 as: 1304313856 which is more like what I would expect. See below.

If anyone can let me know why there is this discrepancy I would really
appreciate it.....
