Actually one system has a ext3 loopback file mounted at /usr/vice/cache and the other has a 10 Gb/afs_ext3 (/dev/sda1) directly pointed to in the cacheinfo and the 230Gb /vicepa is on /dev/sda2. I.e. both cache and /vicepa are on the same disk controller.
Since I'm using hpt_rraid_133 pci cards and 4 120GB drives set up as raid 0/1 per controller, if the OS file system crashes I can easily move the the controller card and the 4 drives to another system and come right back up. I've had to do this with both of my 2K server boxes after 6 sequential power outages ran the MGE EX20 ups's down and trashed the C: drives. Both machines blue screened. Of course I didn't have the smtp ports listening to the ups for a power warning which would trigger a soft shutdown! Fortunately the raid controllers were on the D: drive and my archived data survived intact on both 2K servers. My linux boxes survived quite well. I'm basically looking for 50+ year longevity for the files, independent of the hardware and need to get to a redundant central file server from remote locations in Alaska. Then my clients can get to site technical data and hi res digital pictures either by ftp or afs. I'm really impressed by AFS. There are 2 250Gb P3 file servers up and running here. They cost about $1500 ea. The cheap IDE raid works fine. I pulled a cable off 2 drives to test it and there's a utility hptraid that will rescan and resync the 4 ide drives..
