Squid Posted May 13, 2019 Share Posted May 13, 2019 That's great, can you also make sure it's detected for SAS devices? It uses sdparm which is now included with v6.7:https://forums.unraid.net/topic/72862-drive-write-speeds-really-slow-solved/ Is there ANY adverse effects from running hdparm -W /dev/sdx on a SAS device?Sent via telekinesis Quote Link to comment

yendi Posted May 14, 2019 Author Share Posted May 14, 2019 The setting does not persist with reboot, is there a way to make it permanent? Quote Link to comment

I suspected that, best bet for now it to have a user script on array startup enabling it, hopefully LT will enable it for all array drives in the future. Quote Link to comment

Could you direct me on how to do it? Thanks Quote Link to comment
JorgeB Posted May 14, 2019 Share Posted May 14, 2019 Install user scripts plugin, create a new script with just the hdparm command and schedule it to run at first array start. Note that if you change any hardware the sd identifier can change, though you can use sd* to run the command on all devices, it won't cause any harm. Quote Link to comment

psykix Posted May 14, 2019 Share Posted May 14, 2019 Can I just add this command to the Go file? I already have a command in there to disable ACPI power meter to fix the log getting spammed with error messages. Quote Link to comment

Yes, but I would still recommend user scripts since there's a large chance you forget about adding it in the future, if it's no longer needed, though in this case it shouldn't cause any issues. 1 Quote Link to comment
