Error while mounting reiser4 filesystem

Question

I'm using Debian 6.03 (2.6.32-5-amd64) with LVM configured. For testing I created testfs logical volume and formatted it in reiser4 filesystem. But when I try:

# mount /dev/lv-group/testfs /mnt

it says:

mount: unknown filesystem type 'reiser4'

reiser4progs are also installed. What's the problem?

What feature are you using the reiser filesystem for over some of the other very stable filesystems out there like ext4? ext3? xfs? — mdpc, Mar 19 '12 at 18:19

You aren't running a patched kernel with reiser4 support. It was never merged into the mainline kernel and since Hans Reiser is in prison for the murder of his Wife, it is a dead filesystem. If you are looking for similar features, look at btrfs, but it is still not ready for production environments.

ok, is it good idea to use btrfs in system which reads/writes ~2k or more small files? – mickey Mar 19 '12 at 18:24
@mickey, yes, btrfs handles small files well. – psusi Mar 19 '12 at 20:37
