Tunables: vfs.zfs.trim 0 doesn't work

[floh]

Hello, I need to turn of trim because the ssd doesn't support TRIM. *sigh*

I added an entry in tuneables:
vfs.zfs.trim 0

But it didn't affect and trim is still enabled and I get errors:

I doublechecked:

Code Select Expand

root@OPNsense:~ # sysctl vfs.zfs.trim
vfs.zfs.trim.max_interval: 1
vfs.zfs.trim.timeout: 30
vfs.zfs.trim.txg_delay: 32
vfs.zfs.trim.enabled: 1

Code Select Expand

root@OPNsense:~ # grep trim /boot/loader.conf
vfs.zfs.trim="0"

Hm, whats wrong here?

Best regards

Stupid me... ::)

WRONG:

Code Select Expand

vfs.zfs.trim 0

Correct:

Code Select Expand

vfs.zfs.trim.enabled 0

Now it's working as expected.
