Hello, Thanks for all the tips from Jeff, Edward and Christian. I used the following commands to make a reiser4 partition on a unformatted /dev/sda # mkfs.reiser4 -o create=ccreg40,compress=lzo1 /dev/sda -fy # fsck.reiser4 --fix /dev/sda -y # mkdir /reiser4 # mount -t reiser4 /dev/sda /reiser4 Other output notes, shows: ------------------------- # modprobe -v reiser4 insmod /lib/modules/2.6.25.9-0.2-default/kernel/lib/zlib_deflate/zlib_deflate.ko insmod /lib/modules/2.6.25.9-0.2-default/kernel/lib/lzo/lzo_compress.ko insmod /lib/modules/2.6.25.9-0.2-default/kernel/lib/lzo/lzo_decompress.ko insmod /lib/modules/2.6.25.9-0.2-default/weak-updates/reiser4.ko # fsck.reiser4 --fix /dev/sda -y ******************************************************************* This is an EXPERIMENTAL version of fsck.reiser4. Read README first. ******************************************************************* Fscking the /dev/sda block device. Will fix minor corruptions of the Reiser4 SuperBlock. Will fix minor corruptions of the Reiser4 FileSystem. ***** fsck.reiser4 started at Mon Jul 14 22:40:14 2008 Reiser4 fs was detected on /dev/sda.

On unmounting the filesystem I'll use: # umount /dev/sda I can do some basic file tests, I'll post the results.
