Jonas Pfefferle commented on CRAIL-93:
--------------------------------------
[~dcrespi] you should be able to get the latest version of Crail by compiling
from Master. Let me know if that works for you. A new release will probably
have to wait a while since we try to bundle a few things into it.
> Using Crail with NVMf, the Default NQN also attaches the port number to the
> name.

> 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
>
> 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.
