The only thing on SSD is the OS itself.  I have partitions for /efi,
/boot with ext2, / and /var with ext4.  I'll set up fstrim later on. 
Given I have a 1TB stick and left well over 100GBs unused, I should have
room left over to last a while.  On my todo list tho.  Would once a
month be often enough tho?  I update each weekend.  Other than that, not
much changes really.  /home and such is on spinning rust still.  If I
did daily updates, might be a better plan.  Once a week, maybe monthly
will be OK. 

Even once every 3-6 months would be more than enough.  The SSDcronTRIM will 
check if your disk is filling up and will only run fstrim when/if it is 
needed.

https://chmatse.github.io/SSDcronTRIM/

That's not in the Gentoo tree.  Hmmmmm.  

For systemd, fstrim ships with a unit file to run it once a week. You could 
easily create something for cron. When my NAS is up again (my last remaining 
Gentoo system) I could look at how I did it.


I ran fstrim on my root and var partitions and got this. 


root@Gentoo-1 / # fstrim -v /
/: 13.7 GiB (14676369408 bytes) trimmed
root@Gentoo-1 / # fstrim -v /var
/var: 43.9 GiB (47162359808 bytes) trimmed
root@Gentoo-1 / #


It looks like /var changes more than root does.

The size in the output is usually simply the entire free space. AFAIK fstrim 
does not remember what it trimmed at the previous run.

That doesn't match.  They may have changed something. 


%USED   USED     AVAILABLE  TOTAL MOUNTED ON
11.3%        24.2G    348.5G            392.7G /
37.1%        47.3G    110.8G            176.1G /var


I made those big since I hope to be using that thing for a while and nothing is on LVM or anything.  Adding more space could get interesting.  I went big and still have almost 200GBs unused.  



        

          
I kinda wish I just
could run it on the whole m.2 stick and it do its thing regardless of
mount point.  From the looks of the man page tho, that isn't a option. 


        

        
fstrim -a runs on all file systems. If there is unassigned (unpartitioned) 
space on your SSD, then that space is not written to anyways, thus there is 
no need for trimming that.


      

    

    

    I just created this.  I think this will work.  

    

    

    root@Gentoo-1 / # cat /etc/cron.monthly/fstrim-nvme 

    #!/bin/sh

    

    fstrim -v /

    fstrim -v /var

    root@Gentoo-1 / # 

    

    

    I'll try to remember when the next month comes up and see if it ran
    or not.  It did when I ran run-parts thingy.  

    

    I think once a month is plenty soon enough.  Weekly would just be to
    much.  In another decade, we may not have to do anything to keep
    these things going.  They just do their thing internally.  Heck,
    they have improved a lot over the past decade.
