@johan851 I'm not sure what the errors mean, but the last 5 occurred at powered on hour 43,975 (current is 44,011)... did something happen around ~36hrs ago? Someone more knowledgeable will need to help with the those errors, but it appears they're due to read errors, possibly a few write errors when trying to set drive options
(enable write cache & read look-ahead).
Something that's highly concerning are your drive temps, as 56C is WAY to high... it should normally be in the 30's, and under heavy load, low 40s (anything over 40 is high and of concern).
Until someone with more knowledge replies, I would replace the drive with a spare and do a resilver, as it's better to be safe than sorry... especially with a drive that's near, or at, it's EOL [

- Two things that would likely show any hardware issues is a long S.M.A.R.T test (
smartctl -t long /dev/ada5
) and running a HDD benchmark test afterwards for a heavy drive load (look for higher than normal seek times and low r/w speeds).
- There were a few postings I found via Google that mentioned it could be the sign of bad blocks, but again, I don't have a lot of experience troubleshooting HDD errors, so someone with more knowledge than I will need to chime in for adequate help to be given.
