why should any file be there, just create it.
All files in
/etc/modprobe.d ending with .conf are read, if they apply to a module they will be enforced on module load, makes no sense to create a dummy file for every module possible, there'd be tens of thousands files..
See also docs of modpobe, e.g.:
man modprobe.d ( https://manpages.debian.org/buster/kmod/modprobe.d.5.en.html )

The conclusion rather is that you did it wrong..
Post your file, it has to look like https://pve.proxmox.com/pve-docs/chapter-sysadmin.html#_limit_zfs_memory_usage

How can I do it wrong when it's after your docs ?
Code:
# ZFS tuning for a proxmox machine that reserves 64GB for ZFS
#
# Don't let ZFS use less than 4GB and more than 64GB
options zfs zfs_arc_min=4294967296
options zfs zfs_arc_max=68719476736
#
# disabling prefetch is no longer required
options zfs l2arc_noprefetch=0
This is not a contradiction, if you would have 128 GB it would still be true.
How did you check that ZFS uses 50%? Unless you provide some information, we cannot help you further.
I`m not sure I understand any of this ?
Here you go:

Thank you.
First:
* Please always post the command that was used in output too, so that possible problems with the command itself can be seen.
* If you ask people for help, please state was much information as you can and don't start blaming right away (I don't follow this all the time, but at least we can try, right?)
Now new questions:
* I guess you have 256 GB installed? (that should have been in the 8th post)
* Do you have PVE running ON your ZFS pool?
* If so, did you rebuild your initramfs after changing the modprobe setting?
* Please list all files in /etc/modprobe.d
I don't know what are you insinuating, or what others understood; I have not blamed anyone. A staff member said "I`m probably not doing it right", insinuating I am dumb or something.
* Yes
* Yes
* No, this is not mentioned clearly
* Here:

Yes, and that probably implied that we do not have more information, therefore I requested it. If you would have stated all commands you used (and did not use), you could have an answer faster. You also stated that
Which is after the fact not true:
It is clearly written in the documentation Thomas linked that you have to do that in order to get it to work:
So please try this and it should work.
