@wendell along with the videos you have been doing explaining RAID and BTRFS/ZFS can you give an overview and full explanation of S.M.A.R.T reporting and what the data contained within actually means and what are acceptable numbers and the point at which disk replacement should be considered?
Anyone else who can explain feel free to chime in.
smart is a log, nothing else.
If you have warnings on smart -> it means your drive is failing, and you should look for replacement. SMART is monitoring various things,
bad sectors replaced
spin up times
errors / reads
and stuff like that...
Yeah I get what it is doing but not what the numbers mean - for example one of my disks has this
Seek error rate - threshold 30 current value 75 worst value 60 raw data 39149560 status OK
so what does that actually mean?
each drive will have different values, and some will have different meanings.
from what I understand difference by 30 will cause status BAD
