> Key: CRAIL-93
> URL: https://issues.apache.org/jira/browse/CRAIL-93
> Project: Apache Crail
> Issue Type: Bug
> Affects Versions: 1.2
> Environment: I'm running crail nodes with docker containers, on a Ubuntu 18.04 base.
> Reporter: David Crespi
> Assignee: Jonas Pfefferle
> Priority: Critical
> Fix For: 1.2

>
> This is the version I'm actually using: v1.1-2-gf0afadc
> I'm set up to use spdk on the backend to crail. When attempting to attach, it appears that crail needs two subsystems to achieve the connection. Instead of allowing the default name, I have the system variable set: -e NVMF_NQN="nqn.2017-06.io.crail:cnode"
> 1) subsystem NQN: nqn.2017-06.io.crail:cnode
> 2) subsystem NQN: nqn.2017-06.io.crail:cnode4420
> 19/03/01 17:46:45 INFO crail: CrailHadoopFileSystem fs initialization done..
> 19/03/01 17:46:45 INFO crail: Connecting to NVMf target at Transport address = /192.168.2.104:4420, subsystem NQN = nqn.2017-06.io.crail:cnode4420
> It appears that the initial connect/discovery of the subsystem uses #1, but using the
> crail commands (crail fs -mkdir /test) uses #2.
> Both have to have a valid namespace attached as well.
>
> It also appears that when using my own subsystem NQN (NVMF_NQN) name, crail wants to generate its own Host NQN. A new one every time. First, how do you learn of that
> NQN, and 2nd, it would be great to disable it if spdk has "allow any hosts" set. It refuses
> to connect to spdk.
