Assuming the problem is /var/log is part of the root filesystem and is crammed 
with millions of files. Assume other drive is /dev/sdb. The general process is 
as follows.

1. Reboot to single-user
2. Add partition #1 to /dev/sdb
3. 'mkreiserfs /dev/sdb1'  # to avoid the whole issue of inodes
4. 'mount /dev/sdb1 /mnt'
5. 'cd /var/log; find . -depth | cpio -pdv /mnt'
6. 'if [ $? -eq 0 ]; then cd ..; mv log log-; rm -rf log-; fi&'
7. 'mkdir log; chmod 755 log
8. 'echo "/dev/sdb1 /var/log reiserfs defaults,notail 0 1" >> /etc/fstab'
9. 'wait'
10. 'umount /mnt; init 6'
