This is also the most confusing column in the fstab file, but knowing what some of the most common options mean, saves you from a big headache. The fourth column in fstab lists all the mount options for the device or partition. That’s why it’s wise to let the system automatically detect the filesystem type of media such as floppies and cdroms.

One floppy might be formatted for Windows and the other for Linux’s Ext2. If you take a look at the example fstab above, you’ll see that the floppy and CD-ROM both have “auto” as their filesystem type.

The 9x series (95, 98, ME) all use Vfat, and the NT series (NT, 2000, XP, Vista, 7) use NTFS but they may be formatted as Vfat, too.Īuto No, this isn’t a filesystem type 🙂 The option “auto” simply means that the filesystem type is detected automatically. Your Windows partitions are probably either Vfat or NTFS. Vfat and ntfs Your USB stick is most likely formatted as Vfat (more widely known as FAT32). The filesystem type “swap” is used in your swap partitions. Swap The filesystem name is self-explanatory. Many Linux distros (including SuSE) have started using ReiserFS as their default filesystem for Linux partitions. Like Ext3, ReiserFS is a journaled filesystem, but it’s much more advanced than Ext3. Reiserfs Your Linux partitions may very well be formatted as ReiserFS. Ext3 is a newer filesystem type that differs from Ext2 in that it’s journaled, meaning that if you turn the computer off without properly shutting down, you shouldn’t lose any data and your system shouldn’t spend ages doing filesystem checks the next time you boot up. Ext2 used to be the standard filesystem for Linux, but these days, Ext3 and ReiserFS are usually the default filesystems for almost every new Linux distro.
Many different filesystems are supported but we’ll take a look at the most common ones only.Įxt2 and ext3 Very likely your Linux partitions are Ext3. The third column in /etc/fstab specifies the filesystem type of the device or partition. This is done automatically when your Linux system boots up… if it wouldn’t, you’d have a hard time using your cool Linux system because all the programs you use are in / and you wouldn’t be able to run them if / wasn’t mounted! But how does the system know where you want to mount /dev/hda2 and /dev/hdb1? By looking at the /etc/fstab file of course.
There are lines that look like this:Īs you’ve learned, these lines mean that /dev/hda2 will be mounted to / and /dev/hdb1 to /home. For example, have a look at the example fstab above. Some partitions and devices are also automatically mounted when your Linux system boots up. Just make sure the mount point is a directory that already exists on your system. You can freely change the default mount points listed in /etc/fstab if you’re not satisfied with the defaults your distro has given you. If there is no entry for /dev/fd0 in my fstab when I issue the command above, mount gets very confused because it doesn’t know where to mount the floppy. … my floppy will be mounted in /media/floppy, because that’s the default mount point specified in /etc/fstab. What does all this mean? If I type the following command: As you probably noticed when looking at the example fstab, I use SuSE’s mount points as an example.
Most distros create them under /mnt, but some (at least SuSE) under /media. Like you already learned from the Mounting tuXfile, most Linux distros create special directories for mount points.
That is the directory where the device will be mounted if you don’t specify any other mount point when mounting the device. The mount point specified for a device in /etc/fstab is its default mount point. They tell the mount command exactly the same things that you tell mount when you mount stuff manually: what is the device or partition, and what is the mount point. The first and second columns should be pretty straightforward.
