Bug Description

Binary package hint: partman-iscsi

On a recent Maverick install to iscsi root, the file /etc/iscsi.initramfs contained these four lines at the end:

ISCSI_USERNAME="(null)"
ISCSI_PASSWORD="(null)"
ISCSI_IN_USERNAME="(null)"
ISCSI_IN_PASSWORD="(null)"

This seems to have come from partman-iscsi's finish.d/iscsi_settings script.
This prevents proper login and boot. The values came from the kernel:

$ cd /sys/devices/platform/host2/session1/iscsi_session/session1
$ sudo grep . {username,password}{,_in}
username:(null)
username_in:(null)
password:(null)
password_in:(null)

And it is still present in the release. Username and password also dont get set, when setting them while the installation.

Got around it with editing the initrd on an other computer (https://bbs.archlinux.org/viewtopic.php?pid=282849).
After this step, the connection gets "operational", but hangs afterwards for some minutes.

Then many message like this appear:

Hi Jan,

The later hang is probably because of a change in the kernel (>2.6.32) that breaks open-iscsi 2.0.871.
I just reported that one to Debian http://bugs.debian.org/603990

But partman-iscsi is definitely the culprit for this installation bug. What's the hold-up? In the interest of trying to move things along, I'll attach a patch that should fix it (but is untested).

Our (qty.5) Maverick 10.10 disk-less servers perfectly match Debian bug #603990

Our affected iSCSI boot scenarios:
servers which (initrd) from USB key (/boot partition) then mount iSCSI [root /] affected
servers which (initrd) from iSCSI-enabled NIC (/ partition) also affected
 * All servers loose iSCSI-root (/) device mount upon /etc/init.d/open-iscsi start
 * Issue is present from fresh-installation via Marverick 10.10 (server-cd/iso)

Thanks for this. I haven't yet had time to look at upgrading open-iscsi, but I'll try to do so before the natty release. In the meantime Jim's patch seems like a decent workaround.

This bug was fixed in the package partman-iscsi - 16

---------------
partman-iscsi (16) natty; urgency=low

  [ Jim Paris ]
  * Work around username/password being "(null)", due to a kernel change
    which open-iscsi doesn't handle yet (LP: #625013).
