New HDD, mounting trouble

Jukas · 01-17-2006, 05:34 PM

I tried to put a new hdd in my Debian machine today, and even though I thought I did everything correctly it's not mounting properly. Can anyone point out my mistake(s)?

I created two partitions as showing here

Quote:

nix:/dev# fdisk -l /dev/hdc

Disk /dev/hdc: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hdc1 1 5000 40162468+ 83 Linux
/dev/hdc2 5001 19457 116125852+ 83 Linux

I ran mke2fs -j on them both, and both are showing as ext3 filesystem (matches the rest of my server). If I go into parted it shows both of them

Quote:

(parted) select /dev/hdc
Using /dev/hdc
(parted) print
Disk geometry for /dev/hdc: 0.000-152627.835 megabytes
Disk label type: msdos
Minor Start End Type Filesystem Flags
1 0.031 39221.191 primary ext3
2 39221.191 152625.344 primary ext3

and when I check /etc/fstab I see the following

Quote:

/dev/hdc1 /backup ext3 defaults 0 0
/dev/hdc2 /ftp ext3 defaults,usrquota,grpquota 0 2

but when I try and cd to either /backup or /ftp I get the following errors

Quote:

nix:/dev# cd /ftp
bash: cd: /ftp: No such file or directory
nix:/dev# cd /backup
bash: cd: /backup: No such file or directory

What did I do wrong?

Now that you have created the partitions, you have to mount them before you can cd into them.

You also should make sure you created the mount points. I.e.: cd to /, then su to root. Then mkdir /ftp and mkdir /backup to create the mount points named in /etc/fstab.

mount /dev/hdc1
mount /dev/hdc2

Also make sure that the mount points are created (/ftp and /backup)

If you added a new hard drive then you will have a new device name. You only told us about one device, /dev/hdc.Please send me what are the results if 'df' and 'sfdisk -l' at the command line.

That's where I screwed up. I didn't realize I had to mkdir /ftp and /backup before fstab would mount them.

Is it usual to have a large amount of overhead with a large drive? Now that I've got them mounted I'm seeing

Quote:

/dev/hdc1 16G 129M 15G 1% /backup
/dev/hdc2 128G 129M 122G 1% /ftp

Combined that's 144gb total, on a 160GB drive. Is it normal to lose 10% under linux?

Remember, 160GB = 160,000,000,000 bytes. Exept the computer reads 1k as 1024, so it's not the full 160.

Stupid naming conventions
