Easy disk/LVM question
 

I have just installed Fedora Core 8 on an AMD Geode system. Its quicker than spit on a skittle. Its the only OS on this system.

I have been doing Unix for 25 years, but I know a lot more AIX, HPUX and Solaris than I do Linux.

The OS is installed on an internal 40GB disk. I've also installed a 300GB disk that I want to mount at /mnt1.

The output from fdisk -l is:
========================================================================
[root@hostname]# fdisk -l

Disk /dev/dm-0 doesn't contain a valid partition table

Where did disks DM-0 and DM -1 come from?

How do I format and mount /dev/sdb?
I don't need LVM on this system. This system can be 'dumb as a stump' for now.

Can anyone give me a quick-and-dirty overview?
(this would be easy in AIX: I love SMIT)

Change the type to Linux. You can do that in fdisk or cfdisk.... you apparently already know how to do that since you partitioned it :)

I am guessing that the dm-0 crap is the lvm device name... but I dont know lvm, and you said it can be dumb as a rock so lets not use it :p


# Create a filesystem on the device
mkfs.ext3 /dev/sdb1



# Mount it so it is accessable now
mount /dev/sdb1 /mnt

# Make it keep working when you reboot.
# Add this line to /etc/fstab
/dev/sdb1 /mnt reiserfs defaults 1 2
