Hi,

Can I just do this?

You know the usual rules about fsck'ing a mounted file system?
Yup...
ext4 reduces to ext3, or even ext2 as long as you haven't use extents
(and the journal's reasonably clean).
Yep.
So yes.
That's what I thought.
Haven't they added ext4 to the fsprogs? Is there not a fsck.ext4?
Hmmm...

I think my mixed Etch/Lenny/Squeeze/Sid/Experimental abomination of a
system has had the ext4 fsck capability for quite some time. [0]

0. I have lvm2 running on top of Linux md RAID, and don't actually have
any ext4 file sytem partitions to check, so that particular fsck command
was destined to fail. But it shows it's there, when it's needed.
