Hi Antonio, 
   You can do alluxio-start.sh all (or local) NoMount .
   Let us know if that reports an error.

Thanks.

But when I did a "alluxio-start.sh all Mount", I am getting the error:

Formatting RamFS: /mnt/ramdisk (2gb)
mkdir: cannot create directory '/mnt': Permission denied

Thanks.

Hi Antonio,

On Linux you should be able to use the NoMount option, which will use tmpfs instead of ramdisk. However, keep in mind that the performance of tmpfs is not guaranteed as its contents can be swapped out under memory pressure.

Hi,

I am trying to start Alluxio with "all Mount" instead of SudoMount, but I am getting an
error saying only root can unmount the /mnt/ramdisk. 

How can I start Alluxio without sudo access?

Thanks.

Antonio.
