Task "Collect resources usage statistics" fails with error:
exec /usr/local/pem/etc/web_cluster/lvestat.py at host 11068 failed: Traceback (most recent call last): File "/usr/local/pem/etc/web_cluster/lvestat.py", line 4, in <module> import lvehelper ImportError: No module named lvehelper
Also the error could be:
exec /usr/local/pem/etc/web_cluster/lvestat.py at host 12 failed: Traceback (most recent call last): ... TypeError: a class that defines __slots__ without defining __getstate__ cannot be pickled
As a result of 'lve-stats' upgrade, the necessary files (e.g.
lvestat.py) were removed.
Its absence causes the error.
The behavior is caused by software issue #POA-108900.
The fix is planned to be included in one of the future product updates.
lve-stats and the depending packages:
yum downgrade lve-utils-1.5-2.35.el6.cloudlinux.x86_64 alt-python27-cllib-1.2-11.3.el6.cloudlinux.noarch lve-stats-0.10-51.el6.noarch
