ok, thanks.

(I should have mentioned 14-stable amd64 context)

I booted single-user then ran: fsck -y /dev/ada0s1a
fsck_ffs -E /dev/ada0s1a
tunefs -t /dev/ada0s1a
fsck_ffs -E /dev/ada0s1a

then booted multiuser

will console/messages or some other log show when it runs?
smartctl(8) makes no mention of trim.

A tool like "gstat -d" will show columns for deletion which means trim.

Ronald.
 
This can give you some info too.

$ sysctl -a | grep trim
