Description Dwight (Bud) Brown 2016-12-09 14:22:34 UTC 
Document URL: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Performance_Tuning_Guide/sect-Red_Hat_Enterprise_Linux-Performance_Tuning_Guide-Storage_and_File_Systems-Configuration_tools.html

Section Number and Name: 6.3.2. Setting the default I/O scheduler

Describe the issue: 
"To set the default I/O scheduler, specify the scheduler you want to use by appending the elevator parameter to the kernel command line, either at boot time or by editing the /etc/grub2.conf file. "

Typically not recommended to edit /etc/grub2.conf directly AFAIK.

Suggestions for improvement: 

suggest instead of editing /etc/grub2.conf, edit /etc/grub/default, addend the elevator parameter to the GRUB_CMDLINE_LINUX line and then grub2-mkconfig?

Since I believe all the documentation changes made as part of this bug are published, I'm simply closing it as CURRENTRELEASE.

In case it turns out something is missing after all, feel free to reopen it.
