Several. First, see if you CentOS supports that card. The alternative is
to go to Highpoint's website, and look for the driver. You *might* need to
get the source and build it - I had to do that a few months ago, on an old
2260 (I think it is) card, and had to hack the source -they're *not* good
about updates. If you're lucky, they'll have a current driver or source.
Second, on our HBR's (that's a technical term - Honkin' Big RAIDS... <g>),
we use ext4, and RAID 6. Also, for about two years, I keep finding things
that say that although ext4 supports gigantic filesystems, the tools
aren't there yet. The upshot is that I make several volumes and partition
them into 14TB-16TB filesystems.
Besides, if you have a problem with a truly humongous RAID, the rebuild
will finish sometime around next summer....
