What is your own estimation? Is it useable for production systems? What is the recommended code basis? Our customers are _VERY_ conservative (read: bankers), so they are mostly going with mirrors or striped mirrors.
I wouldn't try that at this point. I'm trying to figure out if there is a userbase and how big it is, but the code is still very new.
Is there any performance data for different work loads? Eg. how does it work for file service with different file sizes, read/write patterns.
It seems to be comparable to RAID-5 for reads down to about half the speed of RAID-5 for lots of small writes.
Since most of our customers need database storage RAID1 still seems to be the best appoach.
Probably.
