gardenair · 11-03-2011, 04:26 AM

hi,
I have created an ios file.The file is located in root home directory. To mount the iso file manually i always manually mount it but when i restart the system i lost my mount.

# mount -o loop centos1.iso /mnt/iso/

I want to add it in my fstab .Kindly guide me that how can I do it?

I try myself but it does not mount

# vi /etc/fstab

LABEL=/home /home ext3 defaults 0 0

centos.iso /mnt/iso iso9660 loop,ro,auto 0 0

In my distribution (Slacware) was this okey:

Quote:

full_path_to_file /mnt/iso auto loop 0 0

full_path_to_file example: /home/dusan/install_iso/slackware-13.1-install-dvd.iso

ro,auto - this must you no write. iso9660 is always read only. iso9660 is read only file system. All disk are automont in boot system mounting.

Have fun.

'e' to edit command before booting,'a' to modify the kernel argument before booting or 'c' for a command-line.

What you write to a file?

Press 'e' at the menu and add the number 1 at the end of the line that start with 'kernel' or 'linux', then press enter and 'b', now you should boot to a cli env and change back your fstab file.
Better yet is to choice the recovery mode at the menu, hence you don't need to add the 1 number to the kernel arguments.

and next time when you make experimental changes in fstab
don't restart to check

try this

Code:

#mount -a
this will update your fstab file

#mount
to check mount points

Now boot into your single user mode and try editing your fstab file again

everything looks fine

and as per your current problem
you are unable to make changes in your fstab file?

you can try this

Code:

#cp /etc/fstab  /fstab.orig

#vi /fstab.orig
(edit the line)

#mv /fstab.orig  /etc/fstab

But I don't think there should be any problem in editing fstab file in Single user mode

gardenair · 11-03-2011, 06:13 AM

yes u r correc,i am unable to make changes in your fstab file.
when i use the command which u mention ,it show

Code:

#cp /etc/fstab  /fstab.orig
cp:canot create regular file '/fstab.orig':Read only file system

My fstab file is currently read only that is the reason i can not make changes in it

thanks for your help,
gardenair

okie so I am sure you must be unable to change permission as well,

try this

Code:

#mount / -o remount,rw

or

Code:

#mount / -o -n remount,rw
#mount -n -o remount /

sorry I don't remember the exact syntax for second one..just trying to help

gardenair · 11-03-2011, 06:26 AM

can you share something for other users facing this probleem
is your / partition in sda2?

and next time as I said don't take a risk on rebooting the system
use

Code:

#mount -a

and if your problem is solved mark the thread as solved
