WiredTiger错误(28)：设备上没有空间

Question

我在一个高i/o系统中使用mongodb，我面临以下问题：

2017-08-20T12:40:47.258+0000 E STORAGE [thread2] WiredTiger error (28) [1503232847:252478][1499:0x7f9b34af7700], file:index-7-5300684995096143824.wt, WT_SESSION.checkpoint: /var/lib/mongodb/index-7-5300684995096143824.wt: handle-write: pwrite: failed to write 20480 bytes at offset 178524160: No space left on device 2017-08-20T12:40:47.258+0000 E STORAGE [thread2] WiredTiger error (28) [1503232847:258665][1499:0x7f9b34af7700], file:index-7-5300684995096143824.wt, WT_SESSION.checkpoint: index-7-5300684995096143824.wt: fatal checkpoint failure: No space left on device 2017-08-20T12:40:47.258+0000 E STORAGE [thread2] WiredTiger error (-31804) [1503232847:258687][1499:0x7f9b34af7700], file:index-7-5300684995096143824.wt, WT_SESSION.checkpoint: the process must exit and restart: WT_PANIC: WiredTiger library panic 2017-08-20T12:40:47.259+0000 I - [conn67] Fatal Assertion 28559 at src/mongo/db/storage/wiredtiger/wiredtiger_util.cpp 64 2017-08-20T12:40:47.259+0000 I - [thread2] Fatal Assertion 28558 at src/mongo/db/storage/wiredtiger/wiredtiger_util.cpp 361 2017-08-20T12:40:47.259+0000 I - [conn34] Fatal Assertion 28559 at src/mongo/db/storage/wiredtiger/wiredtiger

这是我的数据库统计数据：

db.stats(); { "db" : "Test", "collections" : 14, "views" : 0, "objects" : 54715317, "avgObjSize" : 1364.7944367936313, "dataSize" : 74675160249, "storageSize" : 23993229312, "numExtents" : 0, "indexes" : 24, "indexSize" : 3197218816, "ok" : 1 }

Answer 1

设备上没有剩余空间

确保您已经在设备上释放了一些空间，然后确保文件权限是正确的(读和写访问)。

如果您认为数据库可能在than之后损坏，请运行：

mongod --repair --dbpath /path/to/data/db

Answer 2

如果在Windows 10上使用Docker，则应检查以下内容：

1. 打开您的Docker桌面应用程序
2. 打开资源>高级，然后向下滚动
3. 检查磁盘图像大小：(100%)使用
4. 在最底层，您可以更改位置，例如，在我的例子中，另一个驱动器，并增加您想要提供给Docker的存储空间。

重新启动您的码头环境。
