Description John Pittman 2016-11-26 19:06:35 UTC

Document URL: 

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Logical_Volume_Manager_Administration/lvm_tags.html

Section Number and Name: 

Appendix D. LVM Object Tags

Describe the issue: 

"Only objects in a volume group can be tagged. Physical volumes lose their tags if they are removed from a volume group; this is because tags are stored as part of the volume group metadata and that is deleted when a physical volume is removed. Snapshots cannot be tagged."

Per https://www.redhat.com/archives/linux-lvm/2012-April/msg00032.html this works and is supported.

Suggestions for improvement: 

Remove the last sentence from the mentioned paragraph.

Draft is updated, will close this bz when the update is on the portal.

Comment 3 Steven J. Levine 2016-11-30 14:19:24 UTC

The two mentions that tagging is not supported on snapshots have been removed from the RHEL 7 version of this document on the Portal:
