After a Live Merge fails, LVM information may not clearly indicate which volumes are actually in use
Issue
-
This article is aimed at an audience familiar with the details of volume chain manipulation during a Live Merge (snapshot deletion).
-
In this case, on a block-based storage domain, the
lvs
command only showed some volumes in the chain to no longer be active or open. -
However, information from other components indicated that these volumes were still in use.
