[kwlug-disc] Video about ZFS mishap(s?)

[L.D. Paniak]

The only fault of ZFS is it enables one to lose data at the PB scale 
with little experience.

Even minimal monitoring of the array would have helped them to avoid 
this episode.

Once you are using mechanical drives of more than a handful of TB, 
RAIDZ3 vdevs are something to consider. Rebuild times are long and bit 
error rates have not gone down in time.
The ServeTheHome RAID reliability calculator is a useful tool (that 
might make you rethink your array):
