Data Collection System Troubleshooting

Experiment Storage Folders Inaccessible

The experiments are stored in `/data/cat`cat on the CAT server, and `/data/tom`tom on the TOM server, both of which should be accessible through NFS protocol on the TOM and CAT server computers as well as Lion, Tiger, Leopard, and Cheetah iMacs. If the experiment storage folders /data/cat and /data/tom are inaccessible, there are 2 main causes:

1. RAID0 memory is not mounted on /data/cat on CAT computer, and /data/tom on TOM computer.
2. NFS mount has not been established between the computers and the iMacs.

Mounting RAID0 Drives

CAT computer has multiple hard drives installed: one hard drive for hosting the Ubuntu operating system, and the other two hard drives are combined using RAID0 protocol. The RAID0 memory location is /dev/md0 and needs to be mounted to /data/cat. To do so, run the mount /dev/md0 /data/cat in the terminal of CAT computer (might need sudo to have permission for mounting).

In the situation where the /data/cat mount is stale, unmount it with umount /data/cat and then re-mount /dev/md0 to it using the command above.
