Thank you for the response. :-)
I installed the package "openzfs":

# man zpool-trim | head -n 7
ZPOOL-TRIM(8) FreeBSD System Manager's Manual
ZPOOL-TRIM(8)
NAME
zpool-trim - initiate TRIM of free space in ZFS storage pool
SYNOPSIS
zpool trim [-dw] [-r rate] [-c|-s] pool [device]<?>
When I try to trim a pool that is on an SSD:
2021-08-30 18:01:18 toor@f2 ~
# zpool trim bootpool 2>&1 | head -n 1
unrecognized command 'trim'
When I try to load the kernel module:
2021-08-30 18:01:22 toor@f2 ~
# kldload openzfs
kldload: an error occurred while loading module openzfs. Please check
dmesg(8) for more details.
2021-08-30 18:02:10 toor@f2 ~
# dmesg | tail -n 2
interface zfsctrl.1 already present in the KLD 'zfs.ko'!
linker_load_file: /boot/modules/openzfs.ko - unsupported file type
zpool-trim(8) mentions an "autotrim" property, but my pool does not seem
to have it:
2021-08-30 18:03:14 toor@f2 ~
# zpool get all bootpool | grep -i trim
Suggestions?
David
