Yes, I do not do raid5. That does not mean I have not used mdadm. I do
raid1+0 (not raid10) and I do not see how that disqualifies me from
pointing out that you have the wrong flags for the intended result.
I also do raidz and will probably grow those arrays when support for
that is added to OpenSolaris.
Likewise, I have used 3ware and know the difference between using 3ware
750x/850x for raid5 and using 3ware boards that come with bbu caches.
I have done software raid and hardware raid for clusters of servers for
a sizable messaging service provider now owned by IBM.
I do not know what makes you think that you can be so full of yourself
to the point of thinking that you do not ever make mistakes.
