After having read this mailing list for a little while, I get the impression that there are at least some people who regularly experience on-disk corruption that ZFS should be able to report and handle. I’ve been running a raidz1 on three 1TB consumer disks for approx. 2 years now (about 90% full), and I scrub the pool every 3-4 weeks and have never had a single error. From the oft-quoted 10^14 error rate that consumer disks are rated at, I should have seen an error by now -- the scrubbing process is not the only activity on the disks, after all, and the data transfer volume from that alone clocks in at almost exactly 10^14 by now.
Not that I’m worried, of course, but it comes at a slight surprise to me. Or does the 10^14 rating just reflect the strength of the on-disk ECC algorithm? _______________________________________________ zfs-discuss mailing list firstname.lastname@example.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
