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 Jesús Serrano Sánchez-Toscano 2017-07-28 13:27:08 UTC
Description of problem:
When using grubby to remove a specific LVM parameter (rd.lvm.lv) from the file /etc/grub2.cfg, it removes an incorrect one. Even if a non-existing combination of VG/LV is given to the argument "--remove-args=rd.lvm.lv=vg/lv", it removes a parameter of type "rd.lvm.lv" instead of giving a warning and not modifying the /etc/grub2.cfg.

Version-Release number of selected component (if applicable):
grubby-8.28-21.el7_3.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Check the occurrences of the parameter 'rd.lvm.lv' from the /etc/grub2.cfg file:

[root@fvm-rhel-7-3-35 ~]# egrep -o 'rd.lvm.lv=\S+' /etc/grub2.cfg | sort -u
rd.lvm.lv=r7vg/root_lv
rd.lvm.lv=r7vg/swap_lv

2. Use grubby to remove the parameter 'rd.lvm.lv' which references to the swap LV:

[root@fvm-rhel-7-3-35 ~]# grubby --update-kernel=ALL --remove-args=rd.lvm.lv=r7vg/swap_lv

3. Check the result of what grubby has deleted:

[root@fvm-rhel-7-3-35 ~]# egrep -o 'rd.lvm.lv=\S+' /etc/grub2.cfg | sort -u
rd.lvm.lv=r7vg/swap_lv


Actual results:
It deletes a wrong parameter 'rd.lvm.lv' from the kernel boot line in the file /etc/grub2.cfg

Expected results:
Grubby should delete only the parameter indicated with the option "--remove-args=vg/lv" or give a warning if it doesn't find it in any of the kernel boot lines from the file /etc/grub2.cfg.
