hi. <--- newb again

is it possible to enter data into fstab for a device such as HD?

how exactly do i write the syntax?

another question.. what is the purpose of the last two digits on the far right of fstab.." 0 0 "

thankx

Not sure what you mean, but assuming of course if you are talking about adding a new HD, then yes it would look something like this...

Code:

/dev/hdb1    /mnt/newhd      ext2      defaults    1 1

of course this is just an example, since if this is a new hard drive and you already have one hd, the first hd would be known as hda followed by a number, and that number represents partitions. If there is only one partition it would be just hda1, the next part of my example is the mount point, where you want to access the hd, the next is the type of filesystem, in this case I just put in the linux ext2 filesystem, defaults for that drive (permissions) then the last part dump filesystem and check. Try man fstab for more details, and also check out this current thread http://www.linuxquestions.org/questi...d.php?t=399605

The man pages are your friend

From the man pages for fstab and mount...

Yes it is possible to enter data into fstab, you need to be logged in as root (or su to root). The columns in /etc/fstab are:

1 Device name. The partition you want to mount, e.g. /dev/hda2 for the 1st partition of your 1st HDD
2 Mount point. The place in the file system you want to mount the partition, e.g. /boot
3 File system type. What do you have the file system formatted as? ext2, ext3, reiserfs...
4 Mount options. Do you want to restrict what can be done on the file system, e.g. noexec means don't allow execution of binaries
5 Dump options. Is by the dump(8) command to determine which file systems need to be dumped. Set to 1 for core file system partitions, 0 for others
6 fsck options. Used to determine in which order the files systems should be checked. The root filesystem should be specified with 1, other file systems with 2, 0 means it doesn't need to be checked

An example:

Code:

/dev/hda10       swap             swap        defaults                         0   0
/dev/hda9        /                ext3        defaults                         1   1
/dev/hda5        /boot            ext3        defaults,ro                      1   2
/dev/hda6        /home            ext3        defaults,rw,nosuid,nodev         1   2
/dev/hda7        /var             ext3        defaults                         1   2
/dev/hda8        /tmp             ext3        defaults,rw,nosuid,nodev,noexec  1   2
/dev/cdrom       /mnt/cdrom       auto        noauto,users,exec,ro             0   0
/dev/dvd         /mnt/dvd         auto        noauto,users,exec,ro             0   0
/dev/sda4        /mnt/dongle      vfat        noauto,users,exec                0   0
/dev/fd0         /mnt/floppy      auto        noauto,users                     0   0
devpts           /dev/pts         devpts      gid=5,mode=620                   0   0
proc             /proc            proc        defaults                         0   0
