Neil Hello
I sincerely hope you will answer this email.As i understand , raid0
zones are aimed for cases where the disks are not symmetric ( or
partitions ) in their sizes.
But this means imbalanced IO. An inbalanced IO, from my application
perspective is a disaster.
I am wondering whether zone number greater than 1 may be an option in mdadm.
I will most thankful for your opinion on this matter.
PS
I managed to expand raid0 ( very very experimental , and only with zone
nr == 1).
I still have to learn how to write the superblocks though because I
cannot re-assemble the raid, and behave according to md rules.
