I've recently received 3 alert notices for one drive in my FreeNAS-11.3-U5, encrypted RAIDZ2 volume, as part of the regular volume scrubs. They are;
I'm confused because of the different messages for the same drive, as well as a zpool status -v shows no errors;
Following joeschmuck's Hard Drive Troubleshooting guide, I ran a long smartctl test on the drive, and I believe the data output indicates 5 unrecoverable errors for the same drive location, but I don't know if this means replace the drive or not. I'd appreciate any additional help in parsing the data;
Lastly, if this drive should be replaced, (I have a spare), I'm anxious to understand the proper procedure to replace a drive in an encrypted volume.
The FreeNAS documentation covers drive replacements here, but there are also separate callouts regarding encrypted volumes. It would have been easier to understand if the documentation simply including the entire process for replacing a drive in an encrypted volume, as well.
So, please feel free to recommend any other guides/videos that can help me understand the proper steps involved.
Thanks..
