Using OpenStack Cinder with LIO target

Published at February 23, 2017 ·  2 min read

What is LIO target? Linux-OI Target is a Linux SCSI target introduced in a kernel v.2.6.38 and supports different fabrics modules like FibreChannel, iSCSI, iSER, etc. It works in a kernel space, so it’s faster than tgtd which is used in Cinder by default. Why do we still use tgtd instead of more faster LIO in Cinder by default? It’s only because we have to support rolling upgrades and we don’t know how to migrate from TGTd to LIO in a such way and pass Grenade successfully....
