User Mode iSCSI Backend

:title: Storage: User Mode iSCSI
|
|
endif::wiki[]
|
|
|
|
Storage pool type: `iscsidirect`
|
|
|
|
This backend provides basically the same functionality as the
|
|
Open-iSCSI backed, but uses a user-level library (package `libiscsi2`)
|
|
to implement it.
|
|
|
|
It should be noted that there are no kernel drivers involved, so this
|
|
can be viewed as performance optimization. But this comes with the
|
|
drawback that you cannot use LVM on top of such iSCSI LUN. So you need
|
|
to manage all space allocations at the storage server side.
|
|
|
|
Configuration
|
|
~~~~~~~~~~~~~
|
|
|
|
The user mode iSCSI backend uses the same configuration options as the
|
|
Open-iSCSI backed.
|
|
|
|
.Configuration Example (`/etc/pve/storage.cfg`)
