Hi,
I have these two pools, four luns each. One has two mirrors x two luns,
the other is one mirror x 4 luns.
I am trying to figure out what the pro's and cons are of these two configs.
One thing I have noticed is that the single mirror 4 lun config can
survive as many as three lun failures. The other config only two.
I am thinking that space efficiency is similar because zfs strips across
all the luns in both configs.
So that being said. I would like to here from others on pro's and cons
of these two approaches.
Thanks ahead,
