NO OS will help you with these issues, since they are usually generated by disk hardware without powerloss protection (which applies to almost all consumer disks and (shame!) even to a significant amount of server disks). Since disks caches are large, non-negligible portions of data in transfer go to Nirwana in case of a powerloss without protection. The resilience of ZFS here is, that, even when no full atomic write could be finished due to a powerloss, or cached atmic writes were lost, ZFS can rewind a couple of write groups to an earlier consistent state, so you will loose some data (which is usually no problem on an rpool since that's mostly log and state data, and the loss covers only a span of a few seconds), but the filesystem is always consistent, so ZFS can cope with lousy hardware pretty well. But in a datacenter, the few seconds lost usually correspond to a pretty large amount of data lost, and in that case, you never want cache loss and invest in proper enterprise hardware. Hope that convinces you to drop some more coins on proper hardware. -- Dr.Udo Grabowski Inst.of Meteorology & Climate Research IMK-ASF-SAT https://www.imk-asf.kit.edu/english/sat.php KIT - Karlsruhe Institute of Technology https://www.kit.edu Postfach 3640,76021 Karlsruhe,Germany T:(+49)721 608-26026 F:-926026
