-----------
Here are some basic specifications:
- Opteron 2350
- Operating system (Opensuse 11) 64 bit on one disk. Reiser4 formatted on
another data disk(SATA)
- Disk formatted in the following way:
# mkfs.reiser4 -o create=ccreg40,compress=lzo1 /dev/sda -fy
# fsck.reiser4 --fix /dev/sda -y
# mkdir /reiser4
# mount -t reiser4 /dev/sda /reiser4
