</span>Actually resize2fs works on mounted file systems as long as you're only<br>
growing it and not shrinking it, including the root filesystem.<br>

</span>No, but naturally you should make a backup just in case, especially when<br>
you do this the first time.<br>
Of course there are some limitations when you need online resizing without<br>
downtime. Then you can only grow a partition without moving it. In other<br>
words you can only resize a partition if there's physical free space directly<br>
after it. (Most of the time this is the case since you usually have the<br>
boot partition first and then the root and maybe a home or data partition,<br>
and most of the time that last one is the one you want to resize ;-) )<br>
Eg. with [boot, root, home] after resizing the physical disk you end up with<br>
[boot, root, home, <frees space>], so you can only resize the home partition.<br>
If you can afford down time you can also use parted to move partitions so that<br>
you can resize any of them. This however takes a lot longer and is a bit<br>
more risky, so in this case you should _always_ make a backup even if you know<br>
what you're doing.<br>
