Description Derek Higgins 2017-11-15 10:37:19 UTC

Description of problem:
On a RHEL 7.4 qcow2 cloud image, in order to boot using a iscsi root disk I've enabled the "iscsi" module in a dracut ramdisk and passed in rd.iscsi.firmware=1.
This works as expected and the image can now be booted over iscsi but the image can no longer be used to boot using a local disk. dracut times out waiting for a iscsi disk to be attached (see below).

In order to remove the need to have 2 slightly different images, the image should be capable to booting in both scenarios

This is now fixed in upstream dracut
https://github.com/dracutdevs/dracut/pull/298

Version-Release number of selected component (if applicable):
dracut-033-502.el7.x86_64
dracut-network-033-502.el7.x86_64
iscsi-initiator-utils-6.2.0.874-4.el7.x86_64
iscsi-initiator-utils-iscsiuio-6.2.0.874-4.el7.x86_64
redhat-release-server-7.4-18.el7.x86_64

How reproducible:
every time

Steps to Reproduce:
Prepare a rhel qcow image to boot over iscsi by
1. adding the iscsi module to the ramdisk (in chroot)
yum install -y iscsi-initiator-utils-6.2.0.874-4.el7.x86_64 iscsi-initiator-utils-iscsiuio-6.2.0.874-4.el7.x86_64
dracut --force --add "network iscsi" /boot/initramfs-3.10.0-693.el7.x86_64.img 3.10.0-693.el7.x86_64
2. Edit the file /etc/default/grub and add rd.iscsi.firmware=1 to GRUB_CMDLINE_LINUX=…
3. reconfigure grub
guestfish -a /tmp/rhel-server-7.4-x86_64-kvm.qcow2 -m /dev/sda1 sh "/sbin/grub2-mkconfig -o /boot/grub2/grub.cfg"
4. Use this image to boot from local disk as would be the usual (e.g. on a openstack cloud)

Comment 6 Martin Banas 2018-08-08 12:26:12 UTC

Hi Derek,
Could you please check if the solution in new dracut package works for you? Preferably on RHEL-7.6 Beta candidate compose.

Thanks a lot
Martin
