Hello, Today we installed biobrew on our cluster, and I am very impressed with how smoothly the install went. (we already tried, and rejected, OSCAR). I have two comments on the install (I don't know if these are biobrew issues, or if they are generic Rocks issues, as I have never installed Rocks before): 1. during the frontend install, the frontend was configured to use hdc=scsi. We have IDE systems, so I had to remove that from grub.conf. 2. we accidentally powered-cycled the frontend, and had to FSCK. I would think that it would be better to use ext3 or some other journalling FS. Kip
