Current Status¶
We have created a github pullrequest (https://github.com/ceph/ceph/pull/2241) for this feature.
Detailed Description¶
- The quota information will be bound to directory in the namespace tree.
- A file/directory could have multiple quota limit by its parent and ancestor directory.
- When application create a file or directory or expand the file size, the client will find all the ancestor directory which have be bound a quota information, and compare the directory's quota and rstat. If quota is excceded, routine will return -EDQUOT.
- The MDS will be use to store quota information in directory's inode_t and push the rstat to client more active.
