Subject: Kernel option to disable TRIM/discard system-wide?
Date: Mon, 23 May 2016 23:01:26 +0200 [thread overview]
Message-ID: <57436FA6.1010801@rabbit.us> (raw)
Hello!
I have looked through the archives, but can not find anything even
remotely related to the subject:
I want to disable trim on my system for good - yet there seems to be no
kernel boot parameter for this.
My rationale is simple: I want best data integrity guarantees, followed
by better battery-life + mechanical robustness (I throw my laptop around
a lot), and only last am I concerned about performance.
There seem to be a new TRIM-related bug discovered every couple months
for quite some time now. Combined with the "metadata leak via dm-crypt"
makes it a no-brainer decision that I want to avoid TRIM system-wide.
I currently have my sytsem configured properly, but I am concerned a
future OS upgrade will introduce some well meaning cron-job or something
along these lines that will re-enable discards without me ever noticing.
Is there a boot parameter I can hard-code for forward-compatible peace
of mind?
Thank you!
