Configuring huge_pages permissions

[Florian Suri-Payer]

Hi,

I was playing around a bit with a postgres cluster and wanted to try out using huge_pages.

However, it seems like I do not have permissions to change the following file: `proc/sys/vm/nr_hugepages`. Is there a way I can get permission to do so? If not that's fine, just curious.

Best,

Florian

If you cannot change it as root (using `sudo`), then maybe it is a RO value
and you will have to change the setting at boot time. This would be a Linux
thing and not related to Cloudlab in particular.

Yeah I was unable to using sudo. It just tells me `-bash: nr_hugepages: Permission denied`

Alright, I'll dig a little!
