File system problem
 

Hi,
I am in a big problem.I don't know what has happened but yesterday suddenly when I was trying to create a directory in /export/home I got this error

mkdir: cannot create directory `scripts': Read-only file system

from /var/log/messages I found that the partition /export/home has been remounted to "read-only" mode and here is the sample log entry
-----------
Apr 23 08:32:22 host1 kernel: ext3_abort called.
Apr 23 08:32:22 host1 kernel: EXT3-fs error (device /export/home): ext3_journal_start_sb: Detected aborted journal

Apr 23 08:32:43 host1 kernel: lost page write due to I/O error on /export/home
--------------------------------
Could someone please explain as why this error surfaces and what should be the solution for this.

Please help me as soon as possible.Very Urgent.

Thanks,

Maybe boot into single user mode, can't tell you how as you did not mention which Linux you're using. When you get a root prompt type: fdisk -l to see your drive/partition layout. If by this command you found your /export/home partition is /dev/hdb1, try running a file system check on the partition with this command: fsck /dev/hdb1, hit enter or the letter y at every question to accept defaults. Hopefully it will work if the file system is mounted read only, it should. Wait till the prompt returns before issuing command: reboot

first form fstab -l check ur drive no.
then mount it again at the preveious mounting point
then run "mount -o remount /export/home" OR "mount -o remount /home"
OR "mount -o remount (partiton number)
then try to make directory again
hope it should work
