[Bug 1639666] Re: install to iscsi root needs kernel args, fails shutdown

[Kevin Otte]

Finally found the startup problem:

$ cat /tmp/iscsi.initramfs 
ISCSI_TARGET_NAME="iqn.2016-11.net.nivex:storage.istest"
ISCSI_TARGET_IP="2606"
ISCSI_TARGET_PORT="a000:a449:5900::4:3260"
ISCSI_TARGET_GROUP="1"
ISCSI_USERNAME="istest"
ISCSI_PASSWORD="123456789012"

Whatever is generating the initramfs arguments (the installer?) appears
to be doing a simple split on first colon to determine the IP and port.
We'll need to find a different way to do that.

Title:
  install to iscsi root needs kernel args, fails shutdown

Status in open-iscsi package in Ubuntu:
  New

Bug description:
  For this system, a pure network boot was not practical, so USB storage
  for the EFI System Partition and /boot are used.

  Steps to reproduce:
  - Use Ubuntu Server installer to log in to iSCSI target
  - Install ESP and /boot on local USB (sda1,2)
  - Install swap and /on resulting block device (sdb1,2)
  - Reboot after install

  Expected result:
  - System boots

  Actual result:
  - iscsistart in the initramfs is unable to connect to the target, failing with the error:
    iscsistart: cannot make a connection to 0.0.10.46:0 (-1,22)

  Workaround:
  - Append
    iscsi_target_ip=2606:a000:a449:5900::4 iscsi_target_port=3260
    to the kernel command line

  The system now boots.

  When attempting to shut down the system, it hangs at
    Stopping Raise network interfaces...
  and kernel messages
    connection1:0: ping timeout...
  begin appearing due to the network being ripped out from under iSCSI.

  I attempted to add _netdev to the options in fstab as suggested by
  research, but this proved ineffective.
