Storage pool type: glusterfs
GlusterFS is a scalable network file system. The system uses a modular design, runs on commodity hardware, and can provide a highly available enterprise storage at low costs. Such system is capable of scaling to several petabytes, and can handle thousands of clients.
|
After a node/brick crash, GlusterFS does a full rsync to make sure data is consistent. This can take a very long time with large files, so this backend is not suitable to store large VM images. |
The backend supports all common storage properties, and adds the following GlusterFS specific options:
GlusterFS volfile server IP or DNS name.
Backup volfile server IP or DNS name.
GlusterFS Volume.
GlusterFS transport: tcp, unix or rdma
glusterfs: Gluster server 10.2.3.4 server2 10.2.3.5 volume glustervol content images,iso
The directory layout and the file naming conventions are inherited from the dir backend.
The storage provides a file level interface, but no native snapshot/clone implementation.
