5 | Storage pool type: `glusterfs` | |
6 | ||
7 | GlusterFS is a salable network file system. The system uses a modular | |
8 | design, runs on commodity hardware, and can provide a highly available | |
9 | enterprise storage at low costs. Such system is capable of scaling to | |
10 | several petabytes, and can handle thousands of clients. | |
11 | ||
12 | NOTE: After a node/brick crash, GlusterFS does a full 'rsync' to make | |
13 | sure data is consistent. This can take a very long time with large | |
14 | files, so this backend is not suitable to store large VM images. | |
15 | ||
16 | Configuration | |
17 | ~~~~~~~~~~~~~ | |
18 | ||
19 | The backend supports all common storage properties, and adds the | |
20 | following GlusterFS specific options: | |
21 | ||
22 | `server`:: | |
23 | ||
24 | GlusterFS volfile server IP or DNS name. | |
25 | ||
26 | `server2`:: | |
27 | ||
28 | Backup volfile server IP or DNS name. | |
29 | ||
30 | `volume`:: | |
31 | ||
32 | GlusterFS Volume. | |
33 | ||
34 | `transport`:: | |
35 | ||
36 | GlusterFS transport: `tcp`, `unix` or `rdma` | |
37 | ||

50 | ||
51 | The directory layout and the file naming conventions are inhertited | |
52 | from the `dir` backend. | |
53 | ||
54 | Storage Features | |
55 | ~~~~~~~~~~~~~~~~ | |
56 | ||
57 | The storage provides a file level interface, but no native | |
