查看Mongo是否正在备份？
1
- 查看MongoDB的进程列表
ps -ef | grep mongo
该命令将列出所有正在运行的MongoDB进程。
- 查看MongoDB的日志文件
tail -f /var/log/mongodb/mongod.log
该命令将打印MongoDB的日志，你可以在日志中查看备份相关的信息。
如果正在进行备份，你可能会看到类似以下消息：
[initandlisten] Invariant failure: !inShutdown() src/mongo/db/operation_context.cpp 415
这意味着MongoDB正在执行备份操作。请注意，备份操作可能需要一些时间，具体时间取决于你的数据量和硬件配置。
2
要查看Mongo是否正在备份，可以使用以下命令：
-
打开Mongo shell：
mongo -
进入admin数据库：
use admin -
运行命令：
db.currentOp()，该命令将返回当前正在执行的操作列表。 -
查找op字段值为“backup”的操作。如果有正在进行的备份操作，则会在列表中显示。
例如，如果有一个正在进行的备份操作，其op字段值为“backup”，它将显示如下所示：
{"opid" : 12345,"active" : true,"secs_running" : 3600,"op" : "backup","ns" : "","query" : { },"msg" : "backup is in progress","numYields" : 0,"locks" : { },"waitingForLock" : false,"lockStats" : { }
}
如果没有任何备份操作正在进行，则不会显示任何内容。
