newly formatted ext3 becomes unmountable after a day

ted_chou12 · 11-18-2011, 11:53 AM

Hi, recently I've done a lot of coding on the external drive 2gb, i saved and load the webserver cgi page quite a lot, and the old one becomes unmountable, so I got another one and I formatted it yesterday as ext3, I coded for a day, and it became unmountable this morning. I wonder why is it so unstable? will fat be more stable? this is quite upsetting. Cause the first time i didnt backup at all, I have backuped this time but I have to reconfigure everything. May I recover it somehow? Did anyone had the same experience? What do I need to do to check the partition?
Thanks,
Ted

is this a flash drive? how did you mount it? did you automount in fstab? if so how did you mount it in fstab?

Hi, this is a flash drive. this is some of the codes from the mount script:

Code:

    ACTION=$(echo ${FORM_mount} | cut -d ' ' -f 1)
    PART=$(echo ${FORM_mount} | cut -d ' ' -f 2)
    if [ "$ACTION" = "Mount" ] ; then
    	/usr/share/snake/automount $PART add
    fi
    if [ "$ACTION" = "Umount" ] ; then
     	/usr/share/snake/automount $PART remove
    fi
    if [ "$ACTION" = "Check" ] ; then
    	echo "<h2>Checking partition $PART integrity</h2>"
    	e2fsck -n /dev/$PART
		echo "<br><b>If an error was found above, Umount the partition to fix it</b><br><br>"
    fi
    if [ "$ACTION" = "Fix" ] ; then
    	echo "<h2>Fixing partition $PART integrity</h2>"
     	/usr/share/snake/automount $PART remove
    	e2fsck -y /dev/$PART
    	/usr/share/snake/automount $PART add

I think it is automount, i managed to capture a file from /dev/sda1 (around 1.85gb), how would I process it?
Thanks,
Ted

Someone told me that

Quote:

Can you try to run e2fsck /dev/sda1 via ssh? Maybe that will fix
things up.

is useful, and indeed! it recover files under /sda1/lost+found. But the minor part (frequently saved files and dir) are not mapped correctly, they are given new dir names like #32425, I wonder if there is anything to fix the mappings? (sorry for asking so much).
Thanks,
