[DOC] Need to recommend setting mount-time context on SELINUX 1.3.2+ clusters
Last modified: 2017-08-08 02:33:33 EDT
Description of problem:
We should strongly encourage any customer running with SELinux enforcing to add a static SELinux context to the OSD mount options in the install guide.
We see in environments with a large number of objects per PG, the directory enumeration speed is negatively impacted by the addition of xattr queries which accompany SELinux context verification. Setting the context at the mount option removes the xattr lookups for context and helps overall disk performance, especially on slower disks.
Version-Release number of selected component (if applicable):
@Mike, please change the target release if it has to be fixed in 1.3.x docs.

@Mike, a gentle reminder.
