question about paritions/disklabel

["Waitman Gobble" <uzimac%da3m0n8t3r.com@localhost>]

Hi,

I'm following the manual about adding a new drive. I was able to add the drive 
but I seem to be missing 'a' and 'b'.. Thought it would be good to see if 
somebody has an explanation instead of finding out down the road I did 
something wrong.

this machine:
# uname -a
NetBSD  6.0_STABLE NetBSD 6.0_STABLE (KAINDA) #1: Wed Feb 13 22:53:31 PST 2013  
da3m0n8t3r@:/usr/obj/sys/arch/amd64/compile/KAINDA amd64


disklabel shows

5 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]
 c: 1953523120      2048     unused      0     0        # (Cyl.      2*- 1938020
)
 d: 1953525168         0     unused      0     0        # (Cyl.      0 - 1938020
)
 e: 1953523120      2048     4.2BSD      0     0     0  # (Cyl.      2*- 1938020


For some reason it says 5 partitions, but only lists 3.



fdisk shows
Partition table:
0: NetBSD (sysid 169)
    start 2048, size 1953523120 (953869 MB, Cyls 0-121601/80/63)
        PBR is not bootable: All bytes are identical (0x00)
1: <UNUSED>
2: <UNUSED>
3: <UNUSED>


So using newfs:

# newfs /dev/rwd1a 
newfs: /dev/rwd1a: open for read: Device not configured



but if i do newfs /dev/rwd1e it's OK

# newfs /dev/rwd1e 
/dev/rwd1e: 953868.7MB (1953523120 sectors) block size 32768, fragment size 4096
        using 1287 cylinder groups of 741.19MB, 23718 blks, 47104 inodes.

# mount
/dev/wd0a on / type ffs (log, local)
kernfs on /kern type kernfs (local)
ptyfs on /dev/pts type ptyfs (local)
procfs on /proc type procfs (local)
/dev/wd1e on /b type ffs (local)

# df -lh
Filesystem         Size       Used      Avail %Cap Mounted on
/dev/wd0a          909G       8.2G       856G   0% /
kernfs             1.0K       1.0K         0B 100% /kern
ptyfs              1.0K       1.0K         0B 100% /dev/pts
procfs             4.0K       4.0K         0B 100% /proc
/dev/wd1e          924G       8.0G       870G   0% /b

To test, I wrote 8 GB file and it 'sticks' 

# ./initwrite 1

# ls -l /b/1
-rw-------  1 root  wheel  8589934592 Feb 16 15:41 /b/1

So it looks OK .. just wondering about a&b. It's a little different than the 
documentation.


Thank you,
