Time to do some TRIMming...
So now that I am on Slackware14.1 , and 3.10 kernel series, TRIM for JFS is now supported, though I can't seem to figure it out. Tried to peruse the man pages for all JFS , nothing really about TRIM, I guess I am looking in the wrong place?
How do I get started with TRIM for JFS for my SSD? :scratch: |
TRIM isn't jfs specific. Just add discard after defaults in your fstab on your ssd partitions,
reboot, and never think about it again. For example, change /dev/sda2 / jfs defaults 1 1 to /dev/sda2 / jfs defaults,discard 1 1 |
Ah ok, where can I get some more info though about that option discard?
Also thanks for the help! :) |
If you are using an SSD, which I assume you are since you are asking about trim, you should add "notime" to your fstab also.
/dev/sda2 / jfs defaults,discard,noatime 1 1 |
To trim the free space of a file system, use fstrim(1).
|
I will look into more info on how to do that, since I don't understand at all how to use it - and don't really want to make any other changes just yet. Overall if I keeping discard option in my fstab is all that I need, then I'm happy right now :)
