ZFS Disk Failure and Recovery

My journey over the past few weeks dealing with and attempting to recover a ‘failed’ hard drive in my 3-year-old ZFS pool using 4x ST3000DM008 7,200 rpm mechanical drives in raidz1.

Special thanks to Mark Furneaux for his videos about ZFS & pfSense which convinced me 4 years ago to abandon hardware RAID on Windows Server 2012 and go with ZFS on Ubuntu (a decision I'm still very happy with). https://www.youtube.com/user/TheUbuntuGuy

The dramatization parody short in this video contains scenes from the 1979 feature film 'The China Syndrome' © Columbia Pictures. Those scenes have undergone a significant transformation using computer graphics to convey a parody which has been done in good faith as ‘fair use’ in accordance with section 107 of the U.S. Copyright Act 1976. https://play.google.com/store/movies/details?id=vCER5ccRr_g (Google Play store link may be blocked in your region) https://en.wikipedia.org/wiki/The_China_Syndrome
