I have the following setup on my server:
16G RAM 64G swap
I want to setup a tmpfs partition with the following options:
- use up to 50% RAM (8G)
- have the total size of tmpfs 8G + swap size = 72G
In other words, I want the first 8G of data in tmpfs go to memory, and anything above that to be written to disk.
Is this possible?
The options I found in tmpfs docs and fstab examples only allowed me to limit the total size of the filesystem. So if I set it to a large number, it may eat up all my available ram. If I set it to a smaller number, it won't eat up the ram, but there may not be enough space for the application needs.
