As usual, not that immediate to find a proper answer on the ‘Net, hence I’m providing one here.

While in Snow Leopard was quite easy to see your ext2/ext3 formatted disks via MacFuse and ext2-fuse, in Lion you need to install another fuse fork and select a special option. That new fork is OSXFUSE, which latest release at the time of this post if from December 2011.

The most common symptom indicating you need this is to try mounting an ext2/3 formatted drive and see the following error:

fuse-ext2 /dev/disk3s1 /Volumes/Movies
dyld: Library not loaded: /usr/local/lib/libfuse.2.dylib
 Referenced from: /usr/local/bin/fuse-ext2
 Reason: image not found

During the installation of OSXFUSE, you need to enable MacFuse Compatibility Layer by flagging the appropriate checkbox as shown below:

Once you’re done with this, replug your ext2/3 formatted drive and it’ll automagically mount it in Finder, giving your deserved magnificent user experience of a Mac user 😉

One of the things I like of Linux is that despite I’m working with it since 1994 I never end learning part of it.

Today my need was the following: I dd a 20 Gb backup onto a 40 Gb HDD and it worked smoothly, but problem is that filesystem on first partition was 20 Gb while partition was 40 Gb (more or less).

Therefore my need was to extend my filesystem to match partition size to benefit of the additional disk space offered by new HDD size. Googling a bit, I discovered a command that did the magic very smoothly: resize2fs.
All I needed to do is launching command followed by device where filesystem needs to be resized, no matter is filesystem is mounted or not, as follows: resize2fs /dev/hda1

Output has pleasantly been the following:

resize2fs 1.40-WIP (14-Nov-2006)
Filesystem at /dev/hda1 is mounted on /; on-line resizing required
old desc_blocks = 2, new_desc_blocks = 3
Performing an on-line resize of /dev/hda1 to 8835742 (4k) blocks.
The filesystem on /dev/hda1 is now 8835742 blocks long.

Useless to say that AFAIK on Windows this is a dream without costly softwares, and even then…
