Description of problem:
Yum is not properly verifying that there is sufficient capacity in the root filesystem when the root filesystem is low on disk space.
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.
