Handle large files by utilising the swap space?

[Ulysses_]

Read somewhere that when tmpfs runs out of memory it can utilize the swap space.  TC seems to be using tmpfs but only files smaller than the free memory can be handled.

Is there a way to extend TC's filesystem so it can hold large files temporarily by utilising the swap space?

tmpfs mounted over / in TC by default amounts to 90% of available RAM.

When a lot of RAM is needed to be used by apps, then files stored in tmpfs would get swapped out to disk, I have observed such on several occasions.

What about when you want more space for files and not more memory for applications?  Can't I modify that 90% default?

Can't I modify that 90% default?

You can change the size at any time with:

mount -o remount,size=95% /
or
mount -o remount,size=3G /

That's great. It has applications in virtualization. It can make a VM's swap space almost as fast as RAM.

Until there is no more RAM left and the VM's swap space gets as fast as the host's swap space.

[ By setting the swap space as a separate .vmdk that is non-persistent and has its REDO file in /home/tc/<VM-specific-directory> ]
