8 | Storage pool type: `iscsidirect` |
9 | ||
10 | This backend provides basically the same functionality as the | |
8c1189b6 | 11 | Open-iSCSI backed, but uses a user-level library (package `libiscsi2`) |
aa039b0f DM |
12 | to implement it. |
13 | ||
14 | It should be noted that there are no kernel drivers involved, so this | |
15 | can be viewed as performance optimization. But this comes with the | |
16 | drawback that you cannot use LVM on top of such iSCSI LUN. So you need | |
17 | to manage all space allocations at the storage server side. | |
18 | ||
19 | Configuration | |
20 | ~~~~~~~~~~~~~ | |
21 | ||
22 | The user mode iSCSI backend uses the same configuration options as the | |
23 | Open-iSCSI backed. | |

35 | NOTE: This backend works with VMs only. Containers cannot use this | |
