How to change pcie_aspm settings on ubuntu server?

Running a server with a pci-express solid state drive, after some i/o read errors i have the suspicion that my drive is shut down thanks to the pcie_aspm manager. (why one would save power on a server -_-)



While trying to edit the pcie_aspm in the /etc/default/grub file, I found that it is not actually configuring it and the pcie_aspm remains in the default mode, checking the state of pcie_aspm in /sys/module/pcie_aspm/parameters/policy. This is set to default, no matter what I try.



Clear steps:




  • changing /etc/default/grub:
    GRUB_CMDLINE_LINUX_DEFAULT="" =>
    GRUB_CMDLINE_LINUX_DEFAULT="pcie_aspm=performance"

  • running update-grub

  • rebooting and checking
    /sys/module/pcie_aspm/parameters/policy

  • no change :(


help would be appreciated since the server is a bit unstable because of this!



Update:
To clarify a little bit more:

OS: Ubuntu Server Ubuntu 16.04.5 LTS


Several sources claiming different solutions (I know these are not the same distro's but at some point you try different things):
Source 1 => pcie_aspm.policy=performance in /etc/default/grub
Source 2 => pcie_aspm=performance in /etc/default/grub
Source 3 => # echo powersave > /sys/module/pcie_aspm/parameters/policy


These did not work for me.

          Ellipse (mathématiques)

          Pour les articles homonymes, voir Ellipse. L'ellipse est le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante. Section du cône ou projection du cercle. En géométrie, une ellipse est une courbe plane fermée obtenue par l’intersection d’un cône de révolution avec un plan, à condition que celui-ci coupe l'axe de rotation du cône ou du cylindre : c'est une conique d'excentricité strictement comprise entre 0 et 1. On peut également la définir comme le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante (sa construction par la méthode du jardinier est très simple). Dans la vie courante, l’ellipse est la forme qu'on perçoit en regardant un cercle en perspective, ou la figure formée par l’ombre d'un disque sur une surface plane. On retrouve aussi, en première approximation [ 1 ] , des ellipses dans les trajectoires des corps célestes (planètes, comètes ou satellites arti...

          Quarter-circle Tiles

          up vote 0 down vote favorite I have $99$ identical square tiles, each with a quarter-circle drawn on it like this: [asy] size(1.5cm); draw(Arc((2,0),1,90,180),red+1); draw((0,0)--(2,0)--(2,2)--(0,2)--(0,0)); [/asy] When I arrange the tiles in a $9times 11$ rectangular grid, each with a random orientation, what is the expected value of the number of full circles I form?
