Mounting File systems

nallanisai · 12-29-2010, 02:30 PM

hi,

i have installed rhel 5.5 on my system....my hard disk capacity is 70G
i gave 60G for '/' while installation
& 100M for /boot
and 4G for swap..

Now i want to create /u01 directory with 30G and mount that directory permanently...when i execute df -h or df -k ...it should show /uo1 directory...

Do you mean you created a 30G partition & filesystem?

If so, simply add an entry to /etc/fstab using /uo1 as the mount point after creating a /uo1 directory.

If you want to "bind" a directory in the heirarchy somewhere else, there is the --bind option to mount or an fstab entry like:

/olddir /newdir none bind

I don't believe this is what you want.

that would go in the /etc/fstab file

something like

Code:

/dev/sdX       /u01  {filesystem} defaults 0       2

where /dev/sdX would be the 30 gig partition (replacing X with whatever it is)

Hi frieza,

There is no free space in the hard disk...only 6G was free..how can i create a partition /dev/sdx with 30G..

i have free space in / can i create a directory /u01 in / and mount that directory permanently..when i execute df -h or df -k it should show /u01 as mounted...

Checkout Gparted, if you don't have it on your system, download the bootable CD.

Hi

As per your mentioned partition scheme, There is no disk space so you can't do that 30G partition.

You have to find some third party utility for Linux to Extend your partition, I don't know its available or not. Wanted to give you suggestion for future that if you are partition and not sure about future than always make partition other than /boot with LVM so you can always extend and reduce your partition.

Hope this helps.

You don't know if these is any free space on his 70G parition. Gparted or df can tell you.
Gparted will do all of all of the above. You need the live CD because you can't alter a partition of a running system.

As per your information as there is not enough free space on hard drive as you have allocated 60G to "/" and 4G to swap, so its not probably possible to do what you are asking for because you need a partition with filesystem allocated to it before mounting any directory on it.

As rightly said by person above me in future use LVM when you are not sure about the partitions and there space as you can always create new Logical Volumes in a volume group and also extend or shrink a existing logical volume.

Thanks !!
