I have a -current system with 3 Conner CP30200 SCSI drives. I have
been using a C/H/S geometry of XXX/8/256 since Rodney mentioned
this as the optimum geometry for SCSI disks and ufs. Prior to that
I used XXX/64/32 as reported by the Adaptec controller.
With the new slice scheme I get this error for all drives:
sd0: raw partition size != slice size
sd0: start 0, end 416107, size 416108
sd0c: start 0, end 413695, size 413696
The capacity reported for these drives is 416108 blocks. It appears
to be complaining that the slice is 416108 blocks but partition c
is only 413696 blocks. Ok, I'll make the c partition == 416108,
who cares. Disklabel says, partition c extends past end of unit
and does not write the label. There are no DOS partitions on these
Conner drives, 100% FreeBSD.
All of my partitions end on cylinder boundaries due to bad experiences
in the past. Do I have to use the bogus geometry reorted by the
drive and rework all of my labels for this message to go away?
I have another system with a 1Gig SCSI disk that has a DOS partiton
and a FreeBSD partition. The physical disk is larger than my c
partition but I do not get any error messages. The capacity of this
disk is 2031705 blocks.
sd0s1: start 32, end = 409599, size 409568: OK
sd0s2: start 409600, end = 2031615, size 1622016: OK
FreeBSD fdisk continues to report bogus partitions. I had to
partition the disk several times with pfdisk.exe before I could
get the new slice stuff to work properly. I know that this is not
what is on the disk.
The data for partition 0 is:
<UNUSED>
The data for partition 1 is:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 0, size 50000 (24 Meg), flag 80
beg: cyl 0/ sector 1/ head 0;
end: cyl 1023/ sector 63/ head 255
