i wouldnt say it defeats the purpose. after a single drive fails you
are on thin ice. if the raid volume goes readonly you are forced
to take action. it was an artecon system btw. i thought disksuite
did something similar with its raid5 implementation but i could be
wrong. i briefly tried it and never went past performance testing.
it works fine for striping drives.

i am not convinced that rx is the problem. especially for the
vos dump.

yeah, i keep forgetting to try that. the only problem really is that
migrating between the regular and namei interface wont be fun. it
would very handy though.
