I really don't understand chinese. According to google translater it seems ESXi can't lock a file.
Which can happen if something crashed and didn't remove a lock. Or its really locked somewhere else.
I've seen that happen with backup servers (they mount a file, crash, don't unmount -> problem).
I've also seen that happen when a VM on a shared datastore was running on a standalone host not managed by vCenter.
I've used the procedure described here VMware Knowledge Base to find the lock owner.
