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

20 | Configuration | |
21 | ~~~~~~~~~~~~~ | |
22 | ||
23 | The user mode iSCSI backend uses the same configuration options as the | |
24 | Open-iSCSI backed. | |
