Description Jan Stodola 2014-11-07 20:58:14 UTC 
Description of problem:
System doesn't boot after installation with rootfs on iSCSI LUN. Booting ends up in dracut emergency shell. Looking at the kernel boot options in grub.cfg, there are no iscsi target/lun parameters and network configuration is missing too:

dracut:/# cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-3.17.2-300.fc21.x86_64 root=UUID=02e386f2-d4af-43ff-9916-5dccbe001317 ro LANG=en_US.UTF-8 console=ttyS0
dracut:/#

Version-Release number of selected component (if applicable):
Fedora 21_TC1
anaconda-21.48.13-1

How reproducible:
always

Steps to Reproduce:
1. start graphical installation
2. add an iSCSI LUN
3. create following partitioning:
/boot and swap on local disk
rootfs on the iSCSI LUN
4. finish the installation and reboot

Actual results:
system doesn't start, cannot mount rootfs

Expected results:
system starts successfully with all filesystems mounted

Comment 9 Fedora Blocker Bugs Application 2014-11-07 21:09:31 UTC 
Proposed as a Blocker for 21-final by Fedora user jstodola using the blocker tracking app because:

 Fedora 21 Final Release Criteria is not met:
The installer must be able to detect (if possible) and install to supported network-attached storage devices. 
Supported network-attached storage types include iSCSI, Fibre Channel and Fibre Channel over Ethernet (FCoE).
Comment 10 Radek Vykydal 2014-11-10 10:52:14 UTC 
Most probably has the same root cause as bug 1161644.
Comment 11 Kamil Páral 2014-11-12 16:15:06 UTC 
Discussed at today's blocker review meeting [1]. Accepted as a blocker. This is a clear violation of the Final criteria: "The installer must be able to detect (if possible) and install to supported network-attached storage devices."

Comment 12 David Shea 2014-11-14 15:07:34 UTC 
Moving to systemd. Like Radek says, the underlying cause is that we can no longer detect iscsi disks as being iscsi. systemd 216 removed ID_PATH from the information passed to us by udev (see http://cgit.freedesktop.org/systemd/systemd/commit/?id=e98bbfd2074e2b1079b7059341eac25741baf319). The problem being that this was an unannounced API change to a base system component, and we kind of need that information.

Comment 14 Zbigniew Jędrzejewski-Szmek 2014-11-16 14:28:21 UTC 
Hm, I don't see the systemd version in either of the reports. systemd-python-216-8.fc21.x86_64 is listed in packaging.log, but I'm not sure if it's the one running when the problem is exhibited. Anyway, this should be fixed by systemd-216-11.fc21 (currently in stable). It'd be great if you could confirm that.
Comment 15 Jan Stodola 2014-11-17 15:39:54 UTC 
Retested on Fedora 21 TC2 with systemd-216-11.fc21, this issue is fixed. Installation finished successfully, iscsi kernel command line parameters are present in grub.conf and system boots after reboot with iSCSI root file system mounted:

[root@rh-g3 ~]# cat /proc/cmdline 
BOOT_IMAGE=/vmlinuz-3.17.2-300.fc21.x86_64 root=UUID=c8364acc-5039-4a44-9511-ca6ae53b2b3a ro netroot=iscsi:@10.16.67.167::3260::iqn.2009-02.com.example:for.all ip=eth0:dhcp iscsi_initiator=iqn.1994-05.com.redhat:4239b0ed319e console=ttyS0,115200 LANG=en_US.UTF-8
[root@rh-g3 ~]#

"udevadm info --export-db" returns ID_PATH for iscsi devices:

E: ID_PATH=ip-10.16.67.167:3260-iscsi-iqn.2009-02.com.example:for.all-lun-1
E: ID_PATH_TAG=ip-10_16_67_167_3260-iscsi-iqn_2009-02_com_example_for_all-lun-1
E: ID_PATH=ip-10.16.67.167:3260-iscsi-iqn.2009-02.com.example:for.all-lun-1
E: ID_PATH_TAG=ip-10_16_67_167_3260-iscsi-iqn_2009-02_com_example_for_all-lun-1

Closing the bug as fixed.
