GVP A2000 030 Combo SCSI Which filesystem?

What WB version are you running? It's only 3.9 that allows 4GB partitions, my recommendation is to keep the boot partition under 2 GB.

500 MB should be fine, the only other problem i can think of is an older version of GVP Firmware. Although I've install a lot of GVP Cards I always preferred Commodore 2091 and Comspec SA1000/2000 SCSI Controllers.
I think SFS requires a specific Filemask setting and the device type should match the gvpscsi device on the standard commodore scsi device.
