根因分析
WiredTiger 存储引擎无法关闭文件句柄,通常是由于文件系统级损坏或过时的 NFS 挂载导致底层文件在 MongoDB 仍持有引用时被删除。
English
The WiredTiger storage engine failed to close a file handle, typically due to a filesystem-level corruption or a stale NFS mount causing the underlying file to be deleted while MongoDB still held a reference.
官方文档

-
停止 mongod,在数据目录上运行 `mongod --repair`,然后重新启动。这会从剩余的数据文件中重建 WiredTiger 元数据。
-
如果修复失败,从最近的备份恢复。使用 `mongorestore` 恢复备份转储。
-
如果使用副本集,删除受影响的节点,清空数据目录并用 `--replSet` 重新启动,从主节点重新同步。
无效尝试
常见但无效的做法:
-
90% 失败
The corruption persists in the WiredTiger metadata; restarting only re-encounters the same error or causes a crash loop.
-
95% 失败
This file contains critical storage engine metadata; removing it makes the database unreadable and requires a full resync from replica set or backup.
-
80% 失败
Running fsck on a mounted filesystem can cause further corruption; MongoDB requires the data directory to be consistent before repair.
