1 | User Mode iSCSI Backend |
| 2 | ----------------------- | |
| 3 | ||
| 4 | Storage pool type: `iscsidirect` | |
| 5 | ||
| 6 | This backend provides basically the same functionality as the | |
| 7 | Open-iSCSI backed, but uses a user-level library (package 'libiscsi2') | |
| 8 | to implement it. | |
| 9 | ||
| 10 | It should be noted that there are no kernel drivers involved, so this | |
| 11 | can be viewed as performance optimization. But this comes with the | |
| 12 | drawback that you cannot use LVM on top of such iSCSI LUN. So you need | |
| 13 | to manage all space allocations at the storage server side. | |
| 14 | ||
| 15 | Configuration | |
| 16 | ~~~~~~~~~~~~~ | |
| 17 | ||
| 18 | The user mode iSCSI backend uses the same configuration options as the | |
| 19 | Open-iSCSI backed. | |

| 31 | NOTE: This backend works with VMs only. Containers cannot use this | |
| 32 | driver. | |
