blacksmith doesnt work : /mnt/huge/buff not found about blacksmith HOT 3 CLOSED

I fixed this issue by creating the /mnt/huge (mkdir /mnt/huge) directory by myself. Not sure if it is the correct workaround.

Hi @AnaMazda,
Additionally to what @T-TROUCHKINE suggested, you also need to enable 1GB super pages in your system.

METHOD 1: The proper way of doing this would be to enable super pages in the GRUB configuration (recommended) by adding following params to GRUB_CMDLINE_LINUX in /etc/default/grub:

GRUB_CMDLINE_LINUX="default_hugepagesz=1G hugepagesz=1G hugepages=1"

After that, you need to run sudo update-grub and reboot the system.

METHOD 2: Alternatively, you could try to just temporarily enable 1GB super pages (i.e., settings will be reverted after a reboot). However, if your system memory is very full and there is no 1GB of contiguous memory available, this might not work. You can try it immediately after a reboot to increase your chances.

Here a ready-to-run Bash script that should do the job:

#!/bin/bash

gbFile="/sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages"
mkdir -p /mnt/huge
mount -t hugetlbfs  -o pagesize=1G,size=1G none /mnt/huge
echo 1 | sudo tee $gbFile 
cat $gbFile

We would appreciate your brief feedback or 👍🏼 . Thanks!
