I am adding a 2tb drive to my Samba install and prepared the disk as a ext3 partition. When trying to mount the disk in telnet I get the message "unknown filesystem type 'ext3'". My ext2 partitions are mounting without issue.

I am on a Belkin F7D7301 running 16454 mega and was having the same issue with 15506 mega.

Any help would be appreciated.

When I do a lsmod the ext2 module is loaded while the ext3 module is not.

Code:

root@DD-WRT:/etc# lsmod

When I try insmod ext3.ko it attempts to load but returns

Code:

root@DD-WRT:/etc# insmod ext3.ko
insmod: cannot insert '/lib/modules/2.6.24.111/kernel/fs/ext3/ext3.ko': invalid parameters

I did a 30/30/30 and reflashed with 16454 big thinking maybe there was something wrong with my last flash. Still cannot mount ext3. When I do a dmesg I saw the following:

Sounds like I'm missing a dependency but I'm clueless as to what. I don't know what to do from here.

Sounds like a bug / build error...

Can't you explicitly mount it as ext2? The only difference between ext2 and ext3 is the journal.

I could but I've had a lot of power issues lately and suffered some data corruption hence the desire for ext3.

No... it's a feature.... :lol:

DD-WRT only loads the modules that are necessary for the first partition on the first storage.
Any other filesystem (cat /proc/filesystems) needs to be loaded manually first.
You could load OTRW. Its automount DOES load the necessary modules.

You could make the first partition ext3

Code:
insmod mbcache
insmod jbd
insmod ext3

Thanks for the info Frater. That worked. I'm in the progress of changing all my external HDD's to ext3.
