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
/sys/module/pcie_aspm/parameters/policy. This is set to default, no matter what I try.
- rebooting and checking
- no change :(
help would be appreciated since the server is a bit unstable because of this!
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 =>
Source 2 =>
Source 3 =>
# echo powersave > /sys/module/pcie_aspm/parameters/policy
These did not work for me.
