Hi Junxiao, Thanks very much for your view!
I reported this problem to ocfs2 devel list long time ago. You can see here: https://oss.oracle.com/pipermail/ocfs2-devel/2015-March/010691.html And I just now test this gain, and the another node cannot find the LABEL on cluster with good condition. If thing's OK on your side, It may be relative to distribution,or other factors. Anyway, I'll take more care about this.
