Increasing clvmd memory consumption during vgscan
Last modified: 2013-02-28 23:07:52 EST
+++ This bug was initially created as a clone of Bug #488219 +++
Description of problem:
If periodically running vgscan in cluster (without any other loc operation),
memory consupmtion for clvmd increase and can cause OOM.
Caused by missing dm_pool_empty() call in VG context refresh path.
(possible workaround should be try to [re]activate some clustered LV,
this should flush the alocated pool data)
Version-Release number of selected component (if applicable):
just run while :; do vgscan; done
while :; do ps wax -o command,rss,vsz | grep [c]lv ; sleep 5 ; done
