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?<br></blockquote><div>Are you using ECC RAM? <br></div></div>If you're not, then you'll see some checksumming/parity calculation errors.<br></div><div>Is this a huge problem? I guess it could be when you consider how important your data is to you.<br>

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.<br>
<br>
So I threw another 16gigs of RAM in there.<br>
<br>
Now it uses 20gigs of RAM (still not touching swap, obviously) and ZFS performance is fine.<br>
