Looks like I may be looking at a possible drive failure or, “normal” wear-in on one of my brand new hard drives (A 4TB Hitachi). I received a lovely error message from FreeNAS indicating that my drive error count increased from 0 to 1, so I shall be monitoring that count to see if it’s rate of increase changes.
In the mean time, and after taking manual backups of data. I decided to get some backup scripts in place so that I don’t have to continuously monitor the situation. I developed a simple script with a touch of ‘hard coding’ to get the job done for now, using a couple posts about grive and BASH. Grive is awesome, grive -f is also equally awesome when forcing a “download” or “pull” from your Google Drive.
Here is a link to my backup script: Backup Script
