5 | Storage pool type: `iscsidirect` | |
6 | ||
7 | This backend provides basically the same functionality as the | |
8c1189b6 | 8 | Open-iSCSI backed, but uses a user-level library (package `libiscsi2`) |
aa039b0f DM |
9 | to implement it. |
10 | ||
11 | It should be noted that there are no kernel drivers involved, so this | |
12 | can be viewed as performance optimization. But this comes with the | |
13 | drawback that you cannot use LVM on top of such iSCSI LUN. So you need | |
14 | to manage all space allocations at the storage server side. | |

16 | Configuration | |
17 | ~~~~~~~~~~~~~ | |
18 | ||
19 | The user mode iSCSI backend uses the same configuration options as the | |
20 | Open-iSCSI backed. | |
