I’m a little hesitant to use Btrfs because I’m not quite sure how to use it. I’m afraid of losing information or having to reinstall it often because I’m a bit clumsy.
I haven’t created a swap partition because my last Arch installations used zram and didn’t give me any problems, but I really need to be able to hibernate. I’ve looked everywhere, but I don’t see any swap on file or anything similar.
I’d love to get some more info on this.
How set up a swap to file and be able to hibernate?
How to adjust the trim, if that’s something you’re comfortable with. I’ve read that it’s suitable for disks like mine, but I’m not sure how to go about it.
I would really appreciate any guidance or references you could offer. I’m currently looking at this:
Then dont use it.
The only reason to want it is for its special features.
If those are not attractive to you then there is no reason.
Besides - btrfs does require special considerations for maintenance and general use.
Thats fine.
Of course zram on its own does not support hibernation.
But you can use zram and a backing swap for hibernation.
Up to you.
I wrote a tutorial on this in the manjaro forum back in the day;
But the actual swapfile/hibernation guide linked from there is written assuming grub;
I’m not sure what you mean.
Generally speaking continuous TRIM is discouraged and periodic trim, on a timer, is the suggestion.
In your case create a swap file on the / disk the size of your physical memory and you should be good to go.
The second decision is what to do with the existing zram. Out of the box Arch/EOS enables zswap, which will lead to weird swapping behavior if used together with zram.
The combination of zram combined with a swap-file/disk isn’t optimal either. Personally I would disable zram and switch to zswap+swap-file exclusively.
If you use Btrfs, continuous trim, a.k.a., discard, is enabled by default when the filesystem is created. This can be disabled by the use of the nodiscard option in the fstab file. If EndeavousOS uses the fstrim timer as well, then you are getting both continuous trim and fstrim timer running together (weird, but since noone seems to be complaining, I guess it works).
If you go with Ext4, then continuous trim, or discard, is not enabled by default, and the fstrim timer is all you need.
