How do I create a file of size 10M, format it with ext3 filesystem and then mount it in /media/fuse?

I tried with

mkfs -t ext3 file

then to mount it

mount -t ext3 file /media/fuse

It didn't work because it said that file wasn't a block device. Can anybody help me?

You just have to add -o loop to the mount command. – enzotib Dec 7 '11 at 19:54
A great tutorial here: ibm.com/developerworks/linux/library/l-linux-filesystem – arrange Dec 7 '11 at 20:07
To loop-mount a ISO file, I do this mount -o loop file.iso /media/iso. – Anonymous Dec 7 '11 at 20:50

Your procedure is correct, but when mounting a file image as a filesystem you have to add the -o loop option to the mount command:

mount -t ext3 -o loop file /media/fuse

Also, the -t ext3 option is not strictly required, because mount can automatically determine the filesystem type.

he is right but forgot to add the way to create a file dd if=/dev/zero of=file bs=1024 count=10240 this is the way to create a 10Mb file... then you can format it with mkfs.ext3 – maniat1k Feb 28 '12 at 19:20
