Well, I went through everything again on the server. Checked the connections again and pulled all the drives out in order to find out which drive was causing the issue. After identifying the problematic drive I turned the server on again. Now it reports the whole pool and the drive as healthy. No checksum errors at all and it has been running for 5 hours now. The new drive I ordered also arrived today, so I can switch the drive at any time. Bit unsure if I should replace it anyway now or just way and see it if the issue returns? I am getting though every two minutes in the console this warning
Code:
2017/12/18 14:49:09 [WARN] agent: Check 'service:nas-health' is now warning
Looking at the FreeNAS bugtracker this seems to be reported as bug. Or should I be concerned about this?
