This is a follow-up to my ZFS woes from a month or so ago. Funny thing. When that machine had 16gigs of RAM + 16gigs of swap, it was using 15gig of RAM and not touching swap at all, and ZFS performace was horrible. So I threw another 16gigs of RAM in there. Now it uses 20gigs of RAM (still not touching swap, obviously) and ZFS performance is fine. Now, I am seeing occasional checksum errors. I stress-tested the heck out of the thing for a week or so (filled up the filesystem, then deleted most the junk I used for that, etc) and when I ran a scrub it found 12 of them. I'm assuming that since I am running multiple redundancies that that's not a huge problem. Is this correct? Should I cronjob a scrub once a month? I'm pretty gald I didn't need to move away from ZFS... --
