I have a perplexing issue where a ZPool Status Report / SMART Report show everything to be OK and then a few hours later I see read / write errors. Considering the SMART report showed the drive was OK, I tried to replace the disk with the same one, but it gave an error because an existing partition was found. Upon that erring, I tried to force it, but that didn't work. I ran a zpool detach which converted that mirror to a stripe. I ran a scrub and rebooted, now I need to figure out:
1. Volume Status: Prior to Issue
3. Volume Status: Post-Scrub / Post-Reboot
Timeline of Events (Prior to Taking Any Action)
- Does that drive really have errors, and
- How to convert that stripe to a mirror
