Yes, it works (for both snapshots and thinsnaps): [root@bp-01 ~]# lvs vg LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert lv vg rwi-a-r--- 500.00m 100.00 [root@bp-01 ~]# lvs -o name,attr,size,segtype,tags vg LV Attr LSize Type LV Tags lv rwi-a-r--- 500.00m raid1 [root@bp-01 ~]# lvcreate -s -L 500M -n snap vg/lv Using default stripesize 64.00 KiB.

I will close this bz when the fix appears on the Portal. The RHEL 6 copy of the LVM manual on the portal no longer includes the two mentions that tagging is not supported on snapshots. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/lvm_tags.html |
