The data cannot be deleted because the hard drive cannot be added. So the method of using mount to another machine (137) space. As follows:
1, 137 on Vim/etc/exports
Added:/mnt/data/mongodb 192.168.10.135 (Rw,no_root_squash)
Then: EXPORTFS-RV
2, Mount 137 of the space to the local,
Mount-t nfs-o RW 192.168.10.155:/mnt/data/mongodb/data/mongodb
3, Stop 135 MongoDB, Kill-2 PID
4, the original starting mode: Toolbox/services/toolbox-mongodb/bin/mongod--dbpath=/data/toolbox-mongodb/db/--fork--logpath=/data/ Toolbox-mongodb/mongo27017.log
Change to: Toolbox/services/toolbox-mongodb/bin/mongod--dbpath=/data/mongodb/db/--fork--logpath=/data/mongodb/db/ Mongo27018.log
In this way, the write data space for MongoDB has been transferred to 137.
5. End
Solve the "internal problem resolution" method for 135 of the way that MongoDB is too large to drive space
