How hard would it be to write a tool like that? Something along the
lines of:
zpool bench raidz disk1 disk2 ... diskN
Let ZFS figure out the best way to set up your disks for you and tell
you how it should be laid out (and even offer a "just do it" flag that
will let it automatically create the pool depending on how it sees it
best)?
The problem is that there are at least 3 knobs to turn (space, RAS, and
performance) and they all interact with each other.
Yes, I know my hardware, and so perhaps I wouldn't need such a tool, but
there are a lot of people out there who don't really know the best way
to use their hardware for the best performance. This would be an
outstanding tool for them.
I've got an idea I'm prototyping, but it isn't ZFS-specific, so I don't
expect to tie it directly to ZFS. Stay tuned...
