• I am trying to get mSATA SSD to enable TRIM in FreeBSD. I have done eveything like tunefs -t enable  on that parition but it doesn't take effect.  I have read through the threads which ask you to touch /root/TRIM_set  and reboot, but this dones't take affect.I am setting ahci_load="YES" as well.

    tunefs -t enable /dev/ufsid/ID

    seems to work, but when the system boots tunefs -p / doesn't show it as enabled.

    Is there anything specific I need to do to ensure TRIM can be enabled for PFSense when running on APU1D4?

  • You must boot to single user mode to enable trim with the tunefs command … it can't be done if the disk is mounted

  • I was having the same difficulty on a RCC-VE 2440.

    I solved it by booting my box with a memstick in liveCD mode, dropping to a shell and running:

    tunefs -t enable /dev/ada0s1a
