metadata & chunk servers


Metadata are kept on metadata servers, while data is kept on chunkservers.

metadata servers

At least two metadata servers, which work in the master-slave mode for failure recovery.


Each file is divided into blocks called chunks (each up to 64 MB) which are stored on the chunkservers.
administrators can choose how many copies of each file are maintained.


  • Trash,
  • Quotas,
  • NFS
