Change in vdsm[master]: [wip] hsm: remove superfluous refreshes at startup
by Federico Simoncelli
Federico Simoncelli has uploaded a new change for review.
Change subject: [wip] hsm: remove superfluous refreshes at startup
......................................................................
[wip] hsm: remove superfluous refreshes at startup
During the startup it's not mandatory to refresh the iscsi connections
(the sdcache is already stale) and the lvm module can handle the lazy
initialization.
