Did you run fsck under single user mode?

There is a reason why the OS puts FS into read-only mode. You may have a bad disk. Can you check your FS setting for "errors=remount-ro" in /etc/fstab?

Hi, Thanks for your replies... @Patrick Yes in ran fsck and e2fsck in signel usermode... @quad3datwork There is no such entries "errors=remount-ro" in my fstab

That's odd. Have you looked at dmesg/syslog and see what caused the OS to put FS into read-only mode? Things don't happen for no reason. And, it's very likely logged.

quad3datwork Thank for your response... i can see the line like the following in dmesg EXT3-fs warning: maximal mount count reached, running e2fsck is recommended EXT3 FS on dm-0, internal journal EXT3-fs: mounted filesystem with ordered data mode. Adding 2048276k swap on /dev/sdb2. Priority:-1 extents:1 Adding 1959920k swap on /dev/sda3. Priority:-2 extents:1 Also is there any possiblity for hacking ? and keep my FS read only - if so how do detect those ?
