can I take RAM as a Virtual disk to store chunk data?

[杨效振]

When we  create create a file or directory we are creating it at the disk through the chunkserver.

it means that the chunkdata are stored at the disk.now I want to make use of part of my RAM, such as 1024m , 

as a part of  disk.In other words I use part of my RAM as a Virtual disk to store the chunkdata.

How can do?do I need to change the source code or just modify configuration file ?

Hello,

After creating and mounting the RAM disk, all you need to do is to put the mount point in chunkserver configuration file. For instance;

chunkServer.chunkDir = /mnt/ram/

Hope this helps. Let me know if you have further questions,
