I have good SMART data but ZFS errors??
I do not know if I fully understand what ZFS errors are or what they mean. Curious if I can get a good explanation on ZFS errors, SMART results and what they mean together and apart from each other. I currently have a drive with 73 ZFS errors as of yesterday morning. As far as it's most recent SMART results, which was from yesterdays schedule test. Those results are pretty good to my understanding. Would this be considered something to not really worry about what so ever yet? I have another drive with 1k ZFS errors and UDMA errors that I was going to see if I could let fully die in the raid as I have yet to experience a drive failure yet. These drives are in a RAIDZ2 so I have redundancy to keep it all spinning and running. I am more worried about corrupt data than I am about a drive just dying outright. Just want to get a better idea of how to interpret this info so I can maintain my systems the best as I can.
