Has anyone tried running sw-raid1 over linux's network block device? I've
been tempted, but not quite tempted enough yet.
Does sw-raid1 require synchronous data xfer for the block devices involved?
If so, can sw-raid1 be told to not require synchronous data xfer? Does it
make any sense to do so?
Could sw-raid1 do reads only from one device, but do writes to both (for
performance on nwb)?
Something else I've been thinking about, but haven't had time to
investigate properly, is intercepting filesystem calls and shipping them
off to another machine, where they are duplicated. Anybody here have an
idea how difficult that would be? Could it be done in a fs-independent way?
Does SCO's Sentinel take one of these approaches, or a completely
different one?
