Thank you Jeremy, i'm already checking your links.
When i installed smartd i configured a daily short test and a weekly
long one for all the drives while the machine remains mostly unused,
never thought it could be a problem reading the documentation and info
/dev/ada0 -a -o on -S on -s (S/../.././03|L/../../2/07)
/dev/ada1 -a -o on -S on -s (S/../.././04|L/../../3/07)
/dev/ada2 -a -o on -S on -s (S/../.././05|L/../../4/07)
/dev/ada3 -a -o on -S on -s (S/../.././06|L/../../5/07)
I'll remove the checks, do you advice for removing the daemon altogether?
