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

15Configuration
16~~~~~~~~~~~~~
17
18The user mode iSCSI backend uses the same configuration options as the
19Open-iSCSI backed.
