Pardon the noise, but I'm wondering if softraid supports nested raid types?
Specifically, I'm looking to do a raid 0+1 over 4 drives. A mirror of
stripes.
wd1 & wd2 would be striped to stripe0
wd3 & wd4 would be striped to stripe1
stripe0 would be mirrored to stripe1.
Is this even possible with bioctl?
I'm currently assembling my hardware, and I would like to at least ask a
high-level question before digging into the low-level areas.
The reason I ask, is the softraid and bioctl man pages do not mention
nesting capabilities. Or, am I going about this the wrong way and should
I concatenate wd1+2 & wd3+3 and then mirror?
I'm not looking to create a bomb-proof solution, just something to
create a little bit of fault tolerance in my home data store.
And lastly, can I create my wd1+2 stripe, populate the data, then create
my second stripe & mirror and rebuild/cross pollinate?
Logically thinking there must be absolutely no problem to do so.
just go through the steps you've just written.
Although you must be warned that the setup may be slow.
