[9fans] two ventis?

[9fans] two ventis?

[Steve Simon]

Can a venti instance be configured to service to two seperate venti
filesystems? They would need different names and different listner
names but can they share a process / buffer cache?

I guess the alternative is to run two seperate instances.

Strictly speaking, isn't venti just content-addressable block storage, not
a file system? Anyway, I'm curious to know what you are going to use this
for.

true

i have my old work archives and rather than merge that venti into my main one i could just mount it via vacfs on demand (from 9fs). but can one venti cope with two incompatible sets of arenas?

I imagine that you would get problems with duplicates. You could duplicate
enough of the caches and internal structures that it would work, but then
you would be close to having two instances of venti anyway. But maybe, if
you removed the assumption that there are no duplicates, and changed venti
to just index the first instance of a score/value pair.
