I am trying to mount ext4
EBS volume in to my EC2 instance in Debian
OS, whenever I try to mount I get the following error:
mount: unknown filesystem type 'ext4'
I googled around and found a link to the solution: http://techtitbits.com/2010/05/mounting-ext4-partitions-on-debian/
No luck, now I get this problem:
mount: unknown filesystem type 'ext4dev'
Not sure what is the exact problem in mounting ext4
file-system. Please help.
Thanks for your time.
NOTE
My kernel version is: 2.6.21.7-2.ec2.v1.2.fc8xen
Debian OS is Lenny 5.0
**ANSWER**
PLEASE DO NOT MOUNT Ext4 filesystem on kernel version < 2.6.28, it will not work,
since Ext4 was introduced only in >= 2.6.28 kernel version.
Please see: http://wiki.debian.org/Ext4

Don't do it. The experimental ext4 module that was included in Lenny isn't safe or sane to use on a disk that you actually want to store data on.
Still, the mount operation should work alright once the test_fs flag is set. What's the exact output from these commands, filled in with the relevant info for your system?
