An alternate configuration, which takes more memory, but might offer a bit more in the way of survivability, would be to not use fs for venti. Instead, run one venti daemon per disk, with independent arenas/indexes. Insert a little Venti proxy between fossil and your daemons; it should try reads on each venti until one returns a block; it should issue writes to all of them. Good luck, -- vs
