Yeah. I have read about zfs to some degree before but somehow missed this until a couple of days ago. For all its flexibility this looks a very bad limitation.

Yeah. I have read about zfs to some degree before but somehow missed this until a couple of days ago. For all its flexibility this looks a very bad limitation. I think this and rebuild time (again related to vdev width) makes zfs very easy to mess up. The goal of bachefs seem to very lofty though there isn't much detail on the implication of raid design. It seemed to suggest it solves the zfs fragmentation problem, gives better r/w performance with a simpler codebase. Anyone who understand the programmers guide well enough to comment on the viability of the architecture? Does it really solves all the problem of a non-distributed huge filesystem capable of working from a single disk to a big array?
