XFS logdev option causes snapshot failure

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:
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.
Nice, the Note addresses the issue raised.
I have added an Important note in "6.4. Formatting and Mounting Bricks" section to address the concern raised in this bug.

[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.
