Hi i386'er,

because of the bad implementation of nfs-server on the linux boxes I have I
decided to try NetBSD for that. To test things I installed NetBSD-i386 on a
Pentium-IIMMX 333 MHz. This is

up to now I didn't compile my own kernel. Instead I use the kernel that is
installed during fresh install.

As you may see I do have 2 SCSI disks

The installation went fine and used sd0 as the disk to install netbsd to.

Disk 0 (sd0) does have the following layout:

$ > fdisk /dev/rsd0a
NetBSD disklabel disk geometry:
cylinders: 2700 heads: 9 sectors/track: 84 (756 sectors/cylinder)

BIOS disk geometry:
cylinders: 1006 heads: 64 sectors/track: 32 (2048 sectors/cylinder)

Partition table:
0: <UNUSED>
1: <UNUSED>
2: <UNUSED>
3: sysid 169 (NetBSD)
    start 0, size 16 (0 MB), flag 0x80
        beg: cylinder    0, head   0, sector  1
        end: cylinder    0, head   0, sector 16

I wondered why the partition 3 only takes 16 blocks. The disklabel has the
following layout:

$ > disklabel -r /dev/rsd0a
# /dev/rsd0a:
type: unknown
disk: netbsd-boot
label: 
flags:
bytes/sector: 512
sectors/track: 84

interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0           # microseconds

8 partitions:

Well, may be netbsd does not care of the partition size given in the partition
table?!

Since this disk does not have any OS installed on it that does not matter.

After having a running system I wanted to use the 4GB disk (sd1, that is
actually target 4 on the scsi-bus). First I fdisk'ed the disk. Now I have the
following partition table:

$ > fdisk /dev/rsd1a
NetBSD disklabel disk geometry:
cylinders: 3712 heads: 21 sectors/track: 107 (2247 sectors/cylinder)

BIOS disk geometry:
cylinders: 522 heads: 255 sectors/track: 63 (16065 sectors/cylinder)

Partition table:
0: sysid 169 (NetBSD)
    start 0, size 8388315 (4095 MB), flag 0x0
        beg: cylinder    0, head   0, sector  1
        end: cylinder  521, head 254, sector 63
1: <UNUSED>
2: <UNUSED>
3: <UNUSED>

The first partition covers the whole disk. I wanted to use the whole disk! o.k.

Lets disklabel the disk. After disklabel'ing the disk I have:

$ > disklabel -r /dev/rsd1a
# /dev/rsd1a:
type: SCSI
disk: ST15150N
label: fictitious
flags:
bytes/sector: 512
sectors/track: 107
tracks/cylinder: 21
sectors/cylinder: 2247
cylinders: 3712
total sectors: 8388315
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0           # microseconds
track-to-track seek: 0  # microseconds
drivedata: 0 

8 partitions:
#        size   offset     fstype   [fsize bsize cpg/sgs]
  a:   262144        0     4.2BSD     1024  8192    16   # (Cyl.    0 - 116*)
  b:   524288   262144       swap                        # (Cyl.  116*- 349*)
  c:  8388315        0     unused        0     0         # (Cyl.    0 - 3733*)
  d:  7601883   786432     4.2BSD     1024  8192    16   # (Cyl.  349*- 3733*)

Up to now everything is fine! But after creating new file systems

$ > newfs /dev/rsd1a
 ... and
$ > newfs /dev/rsd1d

I get the following error when trying to mount the second file system:

mount -t ffs /dev/rsd1a /mnt1
mount -t ffs /dev/rsd1d /mnt2

right after the mount of /mnt2 the console shows the message:

Sep  3 05:02:56 myhost /netbsd: /dev/sd1d: file system not clean (fs_clean=4);
please fsck(8)

If I mount the file systems in reverse order the other file system complains.

Then I tried to fsck a newfs'ed /dev/rsd1a after the file systems on both
netbsd-partitions have been created. The fsck bombs with:

$ > fsck /dev/rsd1a
** /dev/rsd1a

CANNOT READ: BLK 7588032
CONTINUE? [yn] 

If I only create the /dev/rsd1a everything is ok. But that's a __NO GO__ !

Hey, this will drive me crazy !

After the first attempt making the file systems I didn't realize that there are
some errors with these file systems. So I mounted both (/dev/rsd1a and
/dev/rsd1d). But during a find I was wondering that find complains for i-nodes
not correct. I found, that all dir's created in the the root of /mnt1 appear as
well in /mnt2 - I was astonished!

I do have netbsd-pmax and netbsd-sparc running, I have some Linux boxes and
Tru64 boxes as well. I'm not new to UNIX and the different flavours - but please
tell what I'm doing wrong here!!!

TIA
