I cannot believe I was running TN for a year without that tool - absolute gold!
Amazing! This worked for me... THANK YOU!
As a new user, I appreciated this informative piece. It really helped me understand what ZFS is about. Appropriate for newcomers.
Seems to be working great!
This is a must have script for TrueNAS users! It provides everything you need to track drive health! Script is easy to setup, easy to run, and sends a detailed summary of your system's hard drives' status in an email.
Thank you Joeshmuck and NickF (spencer.py addon script)!
Excellent tool for disk health monitoring
Worked perfectly in TrueNAS-SCALE-23.10.0.1
Thank you so much for this excellent resource. For a novice/rookie like me this is a HUGE help!
This is a must have! Love it. I have 47 drives on my truenas scale and this helps me keep them in line. Thank you Joeshmuck!
Thanks for your tool, @jgreco! It helped me pinpoint a bottleneck in my setup – a single connector between the HBA and a 24-port backplane (BPN-SAS3-846EL2). The issue was resolved by connecting two SFF-8643 cables from the SAS3008/9300-8i running firmware 16.00.12.00 to the primary and secondary expander ports on the same backplane. This resolved the "--SLOW--" indication in the parallel array read test upon retesting. For reference, this 24-port backplane has 16x 20TB Seagate Exos X20 ST20000NM007D-3DJ103 SATA 6Gb/s Standard Model FastFormat (512e/4Kn) disks attached to it.

The parallel stress test is actually one of the main goals of the tool, and is meant to bring your awareness to bottleneck issues that might otherwise have gone unnoticed. Funny that all these years later with completely different bus topologies that we still have these problems...
Great introduction to ZFS, really!...Short but just long enough to get you on the right track :) Reading advised for newcomers.
