ZFS: 1; Silent data corruption: 0
As I’ve mentioned, I’ve been very interested in ZFS lately. Well this week, the hypothetical happened to me and ZFS was there to make it a non-event. I was checking up on my newest ZFS’d filesystem (a pair of 1TB drives in a ZFS mirror). I ran ‘zpool status’ to see how the health of the pool was and it reported that one drive had had a checksum error. I’ve been processing gigs of log files from it, so one block error isn’t much of a pattern. I ran a ‘zpool scrub’ to check everything out (it was clean), and I’ll certainly watch that drive a little closer. ZFS made it simple and seamless.
