Description Harold Miller 2015-12-11 21:50:16 UTC 
Document URL: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Administration_Guide/Brick_Configuration.html

Section Number and Name: 11.2.2

Describe the issue: XFS File systems that use external log devices cause snapshots to fail

Suggestions for improvement: Add a Note Block like:

---
NOTE:

The use of Snapshots on XFS filesystems that are formatted with external log devices is not currently supported at the LVM layer.
Do not format your Gluster Bricks with the "-l logdev=<device>" option.

Comment 9 Divya 2016-02-05 03:37:23 UTC 
I have added an Important note in "6.4. Formatting and Mounting Bricks" section to address the concern raised in this bug.

Link to the doc: http://jenkinscat.gsslab.pnq.redhat.com:8080/job/doc-Red_Hat_Gluster_Storage-3.1-Administration_Guide%20%28html-single%29/lastStableBuild/artifact/tmp/en-US/html-single/index.html#Formatting_and_Mounting_Bricks

[Hint: Search for "Snapshots are not supported on bricks formatted" text to easily find the Important note.]

Based on Comment 8, moving the bug to ON_QA.
