Please support Linux-IO in extensions/iscsi in addition to tgtd

[Attila Fazekas]

tgt is the old way for creating and managing iscsi targets, the new way is using Linux-IO.

The new interface is http://linux-iscsi.org/wiki/ConfigFS .

The python helper which also used by cinder: http://linux-iscsi.org/Doc/rtslib/html/

tgt/tgtd utility is not available in the RHEL 7.x and CentOS 7.x base repository (it was available for el6),
however the EPEL repo still have it.

Please support the Linux-IO target as well.

    Support Linux-IO in addition to tgtd

    The iSCSI extension now tries to use Linux-IO first (via rtslib)
    and falls back to tgtd if Linux-IO can't be used (e.g. in the CoreOS-based
    image which uses containers).
