TRIM question for 2.1.5 upgrade to 2.2

[zimba]

Hello All,

I am planning to upgrade to 2.2 from 2.1.5. I currently have TRIM enabled and all is working well. After the upgrade, do I need to re-enable TRIM via the command line? Or does the upgrade process keep the existing TRIM settings?

Many thanks to all of you in advance!

TRIM is a filesystem flag, so as long as the upgrade process does not replace the filesystem TRIM should stay enabled.  Upgrade in place should be OK, but TRIM would not survive a fresh 2.2 install followed by restoring a 2.1 config AFAIK.

It's easy enough to check and drop to single user mode if needed to enable it (unless you're working remotely).

I got some Trim help here if you decide to do a fresh install: https://forum.pfsense.org/index.php?topic=66622.0
