mount_ext2fs: /dev/ad2s5: Operation not permitted
----------------------------------------------------
It's a common problem if the partition is improperly unmounted, such as a forced reboot or a power cycle
The partition needs to be fschk'ed before BSD can mount it. ext2 filesystem is covered by the e2fsprogs utilities.
So you need to install the e2fsprogs utilities if you've not installed, fschk it and then mount the partition.
1) Open a Terminal, #su to root
2) #cd /usr/ports/sysutils/e2fsprogs && make install clean
3) after installing e2fsprogs, do the following,
#e2fsck /dev/ad1s1 (you need to change the partition accordingly)
make sure that the ext2fs.ko module have been loaded.
