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.

+++ This bug was initially created as a clone of Bug #1714888 +++

Description of problem:

Please see also bug 1491786 for more background.


If the root filesystem is low on space, it starts the update but runs out of space during the installation of the RPMs. Yum then fails, leaving the system in a corrupted state.


Version-Release number of selected component (if applicable):
 yum-3.4.3-150.el7.noarch
 kernel-3.10.0-514.6.2.el7.x86_64 (RHEL 7.3)

How reproducible:
-

Steps to Reproduce:
1.1. Build a server with our standard layout including a  3G root filesystem
2. Create a 1.5G file in /usr
	dd if=/dev/urandom of=/usr/bigfile bs=1024k count=1500
3. Update the server:
    yum clean all && yum update -y


Actual results:
RPM installation then fails, leaving packages broken and in an consistent state. The server is then broken; processes no longer can run because dependent libraries are not installed or are installed in inconsistent versions.

Expected results:
Yum transaction check accurately determines if there is enough space before installing packages.

Verified, glibc-all-langpacks rpm size now calculated as the double size of /usr/lib/locale/locale-archive.tmpl file.

Also verified, glibc-all-langpacks mention has been removed from glibc.spec in glibc-2.17-305.el7.
