RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
When booting to an encrypted root volume and the crypttab has been included in the initramfs.img, if the line in the crypttab file does not end in a newline, it is not properly interpreted by dracut. It would be preferable that dracut give a better error message if it cannot read the crypttab file properly. The error during boot looks like this:

Version-Release number of selected component (if applicable):
dracut-004-336.el6_5.2

How reproducible:
Every time.

Steps to Reproduce:
1. Create crypttab file that contains "cryptroot /dev/xvdf /etc/keyfile" (ensure entry in crypttab does not end in a newline)
2. Run dracut, injecting crypttab and keyfile into initramfs.img
3. update grub.conf to boot to encrypted filesystem root=/dev/mapper/cryptroot

Actual results:
dracut: luksOpen /dev/xvdf luks-587e17f6-c6a6-447e-bd9e-e654e7aaedae /etc/keyfile
dracut Warning: No root device "block:/dev/mapper/cryptroot" found

Expected results:
dracut: luksOpen /dev/xvdf cryptroot /etc/keyfile
dracut: Mounted root filesystem /dev/mapper/cryptroot

Additional info:

This is filed against Fedora Rawhide, but:

Version-Release number of selected component (if applicable):
dracut-004-336.el6_5.2

is this supposed to be for RHEL 6 or Fedora? Thanks!

I wasn't able to reproduce with dracut-004-356.el6.noarch and my /etc/crypptab doesn't contain a new line at the end.


Kevin,
can you see if you can reproduce with RHEL 6.6 ?
