Hello all,
I am currently running FBSD 3.0-970209-SNAP and would like to add a new
disk. I installed my new 1Gb IDE drive as a master drive on the second
IDE controller. Using the sysinstall utility program as suggested by the
FBSD FAQ, I created 4 partions ( 400M as DOSFS, 250M, 350M and 40M as
ufs ). Again using the sysinstall utility, I created 1 filesystem on
partition number 2, 2 filesystems on partition 3 and the last partition
is used as a swap filesystem.
Checking the /dev directory, I saw the filesystems are created
accordingly ( wd2s2e, wd2s3e, wd2s3f and wd2s4b ). However when i tried
to mount any of these filesystem i got an error saying
"Incorrect super block."
Example : mount /dev/wd2s2e /mnt/src
/dev/wd2s2e on /mnt/src: Incorrect super block.
Could someone please tell me what else do i need to do to create the
filesystems ? Belows are the results from the fdisk and disklabel
command.
Best regards, Hai Nguyen.
PS : fdisk reports the correct disk geometry but disklabel has its own
opinion.
