Adding a second hard drive

AxXium · 06-22-2005, 09:31 AM

Tonight I will be installing a second IDE hard drive.
I am planning on using it to store all of my backup files.

After I install the hardware, how do I go about setting up Slack to mount this drive as it does the first one at startup?

Notes:

OS = Slackware Current 06-19-2005
Kernel = 2.6.11.11
HD = Two IDE Hard Drives

Hotplugging enabled & UDEV being enabled as well

Should be easy enough

Once it's installed, use fdisk (or cfdisk) to create a partition on it.
mkdir another directory under /mnt, say /mnt/storage, and add a line to /etc/fstab:

Quote:

/dev/hdb1 /mnt/storage ext3 defaults 1 2

Assuming there's only one partition and that it's formatted as ext3. Adjust as necessary :-)

1. cfdisk /dev/hdXX <- where XX is your drive letter and number you just installed to setup the partitioning.

2. mke2fs -j /dev/hdXX <- command to format with journaling, if you use ext3, etc. Run the correct command for whatever type of filesystem you want, mine is only an example.

3. mkdir /directory_name <- the empty directory you want to mount this new drive to.

4. Edit fstab by adding a line like this:

Code:

/dev/hdXX     /mnt/point     fstype    defaults    1   2

/dev/hdXX <- New drive device name.
/mnt/point <- Your empty directory you created to mount to.
fstype <- In my example it would be ext3 cause I formatted it using mke2fs -j
defaults <- All the available options you can set for the mount, defaults is the default used in Slackware
1 2 <- To run fsck on the filesystem with the defaults set.

Wow!!

Thanks trickykid & rose_bud4201!!

I have to say.....

This is an amazing forum !!!

Two more questions......

1. I belive that ext3 has a file size limit of 2GB, is that correct?

2. To use ReiserFS instead I would....

mkreiserfs -j /dev/hdb1

or should I leave the "-j" out because ReiserFS is a journaling filesystem

that part I don't understand.

the -j flag is to specify creation of an ext3 journal (ie, instead of an ext2 filesystem) - check the mke2fs man page for more.

I don't think there is a -j flag for mkreiserfs - like you said, it would be redundant for reiserfs....

The only difference between ext2 and ext3 is the existance of a journal, which is why the command to format a partition with ext2 is "mke2fs" and the command to format a partition with ext3 is "mke2fs -j" - i.e. make me an ext2 filesystem, but give it a journal.

According to this faq:

Quote:

Q: What is the largest possible size of an ext3 filesystem and of files on ext3?

Ext3 can support files up to 1TB. With a 2.4 kernel the filesystem size is limited by the maximal block device size, which is 2TB. In 2.6 the maximum (32-bit CPU) limit is of block devices is 16TB, but ext3 supports only up to 4TB.

I know this is an old post but it was exactly what I needed
