Surely you'd only use GFS for a shared pool of storage. As the largest CF card you can sensibly get atm is around 8GB, that's not a lot of storage to be shared by multiple nodes. Now we use CF cards for embedded boxes, but for exactly the reasons you mentioned (poor MTBF/reduced lifetime due to the read/write process), our cards are invariably read-only filesystems and we use ext2 to get rid of the journaling too. No swap either (which has caused some trouble on one or two occasions, but that's another story).
