gotgt

Simple Golang SCSI Target framework, this includes only one binary, you can start a daemon via gotgt daemon and control it via gotgt list/create/rm.

Build

$ mkdir -p $GOPATH/src/github.com/gostor/
$ cd $GOPATH/src/github.com/gostor/
$ git clone https://github.com/gostor/gotgt gotgt
$ cd gotgt
$ ./autogen.sh
$ ./configure
$ make

How to use

Currenty, there is lack of commands to operate the target and LU, however you can init the target/LU with config file in ~/.gotgt/config.json, such as:

{
  "storages":[
    {
      "deviceID":1000,
      "path":"file:/var/tmp/disk.img",
      "online":true
    }
  ],
  "iscsiportals":[
    {
      "id":0,
      "portal":"127.0.0.1:3260"
    }
  ],
  "iscsitargets":{
    "iqn.2016-09.com.gotgt.gostor:02:example-tgt-0":{
      "tpgts":{
        "1":[0]
      },
      "luns":{
        "0":1000
      }
    }
  }
}

Note: make sure file /var/tmp/disk.img is existed, you can use dd to create it.

Test

You can test this with open-iscsi or libiscsi.
