我最近更换了一个在 GlusterFS 集群中提供砖块的 HDD。我能够将该 HDD 映射回砖块，然后让 GlusterFS 成功复制到它。
然而，整个过程有一个问题似乎对我不起作用。我试图用替换的砖块在卷上运行“heal”命令，但会不断遇到这个问题：
$ gluster volume heal nova

纵观它们，尚不清楚其中是否与这个特定问题有关。
通过上述设置，我最初认为我只能从 GlusterFS 集群的主节点运行修复命令，但事实证明，我真正的问题在于 GlusterFS 集群中的 11 个节点运行 2 个不同的版本GlusterFS 的。
一旦我意识到这一点，我将所有节点更新到最新版本的 GlusterFS (3.7.3) 并且能够从任何节点执行修复，正如人们所期望的那样。
