示例1: _kickGC
# 需要导入模块: from lock import Lock [as 别名]
# 或者: from lock.Lock import acquireNoblock [as 别名]
def _kickGC(self):
# don't bother if an instance already running (this is just an
# optimization to reduce the overhead of forking a new process if we
# don't have to, but the process will check the lock anyways)
lockRunning = Lock(cleanup.LOCK_TYPE_RUNNING, self.uuid)
if not lockRunning.acquireNoblock():
if cleanup.should_preempt(self.session, self.uuid):
util.SMlog("Aborting currently-running coalesce of garbage VDI")
try:

except util.CommandException, e:
if e.code != errno.ETIMEDOUT:
