Mount root filesystem as Read Only

The frequency of power failures in my area is high and each time I have to do a filesystem check manually for the dock to boot from USB again.

I wanted to know how I can mount the / partition as read only. What all changes are to be made etc. Can someone point me to a good guide on how to do it?

I do not know about read-only, however the lenny system installed on my dockstar used ext2, which doesn't handle power failures very good.

I changed mine to a journaling filesystem (ext3), by simply replacing the "ext2" to "ext3" under /etc/fstab
(The kernel automatically adapted the ext2 partition to an ext3 one by adding a journal on the first mount)

cheers,

Oh. So after changing it to ext3 is it working fine after a power failure?

With ext3 Power failures shouldn't be a problem anymore because it is a journaling Filesystem.

But if you use a USB Stick for Storing your system partition be careful because ext3 puts far more write cycles on your stick than ext2 (because of the journal).

Hello,

I changed the /dev/root fstab entry from ext2 to etx3. Yet when I list the mounts after a reboot, I see that the /dev/root is mounted as ext2... :/


any ideas how to force the ext3 mount ?

You also need to run "fw_setenv usb_rootfstype ext3" as root to change it; that variable defaults to ext2 and seems to override /etc/fstab.
