Strange disklabel

[Anders Gytri]

I have recently installed a big disk (1.4 TB sata raid with scsi
interface) on an i386 computer running FreeBSD 5.4-RELEASE-p1. I have 3
partitions on the FreeBSD slice. The disk is working OK, but the disklabel
seem a little strange. For one of the partitions the "fsize bsize bps/cpg"
values are "0 0 0". For the other two partitions these values are
"2048 16384 28552" which I beleve is more normal. The filesystem is
initialized (with newfs). fsck gives no errors.

Partial or full output from the commands "dmesg", "df", "mount", "fdisk
da1", "bsdlabel -A da1s1", "tunefs -p /dev/da1s1e", "fsck /dev/da1s1e" and
"dumpfs /dev/da1s1e" is attached below.

Should I worry about this, or can I ignore it.
