我的 riak 集群有 10 个节点，运行版本 2.9.8。所有节点都是同一个版本。名为[email protected]的节点使用了大约 95% 的磁盘空间。而其他节点仅使用了不到 50% 的磁盘空间。
我试图找出数据压缩错误，就像这篇文章所说的那样：
find . -name "LOG" -exec grep -l 'Compaction error' {} \;

所有分区每个使用大约 30GB，除非节点有压缩错误。这些分区的大小如下：
1.3T ../308285501624487334308589769401090949458673270784
67G ../336830455478606531929755488790080852186328203264
159G ../365375409332725729550921208179070754913983135744
577G ../793549717144513693868406999013919295828807122944
这些压缩错误是否导致磁盘不断增大？修复这些分区/虚拟节点后，空间会被释放吗？如果没有，我该怎么办？
