[SOLVED] understanding fdisk

[zentron]

Hi,
I am just starting off my exploration of linux but have already gotten myself confused. I am trying to merge 2 existing partitions (on the same HDD) into one partition. I thought that df -h was supposed to show the available disks but it shows 2 eventhough I only have one HDD.

Filesystem size Used Available Use% Mounted on
/dev/root 3.0M 3.0M 0 100% /
/dev/discs/disc0/part1 26.9G 128.2M 25.4G 0% /tmp/mnt/disc0_1
/dev/discs/disc0/part2 26.9G 5.7G 19.8G 22% /tmp/mnt/disc0_2



both of the /dev/discs/disc0 are the same hdd but they are listed here as 2 diferent drives... fdisk, which i think shows partitions shows the 2 different partions...


fdisk -l
Device Boot Start End Blocks Id System
/dev/ide/host0/bus0/target0/lun0/part1 1 3570 28675993+ 83 Linux
/dev/ide/host0/bus0/target0/lun0/part2 3571 7140 28676025 83 Linux

Basically what is going on here? How can i delete the 2 partitions on the same /dev/ide/host0.... into one partition since the system seems to think its 2 differnt drives?
Thanks in advance guys

Ok so i managed to remove the 2 partitions and create 1 merged partition listed as /dev/ide/host0/bus0/target0/lun0/part1 . I also run umount to remove the 2 mounts but when i try to mount the single partition it doesnt seem to work.. i run mount /dev/ide/host0/bus0/target0/lun0/part1 /tmp/mnt/disc but then when i run df, it doesnt show up (only the inbuilt root dir).. what am i doing wrong conceptually.. I think my problem might just be not understanding correctly what is going on...
mount /dev/ide/host0/bus0/target0/lun0/part1 /tmp/mnt/disc
give
Mountng ...... failed : Invalid argument..
What argument am i forgetting? I thought that no no options on mount command should work fine?? Am I supposed to set a filesystem on it or something?

Hello and welcome,
Did you forget to format the new partition before trying to mount it?

I thought i had but maybe i was trying to format the wrong thing or it didnt complete properly because i reformatted using mkfs.ext3 and remounted and it worked!! I feel stupid for having such a simple mistake that i thought i had covered already! Thanks Mike!
