It would be interesting to see the ps -l output for that process and any other Vinum-related processes. > Also, I reconfured my scsi (2940uw) to the lowest transfer speed, > disabled wide negotation (these are wide fast drives), disabled > disconnect and disabled synchronous transfers.

Do: vinum -> setstate up striped.p0.s1 striped.p0 When you're happy with the data, do: vinum -> setdaemon 4 vinum -> saveconfig Greg -- When replying to this message, please copy the original recipients.
