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. ~~~~~~~~~~~~~~~~~~Additional info~~~~~~~~~~~~~~~~~~ On a freshly installed RHEL7.3 machine: ~~~ # df -B1 / Filesystem 1B-blocks Used Available Use% Mounted on /dev/mapper/rhel-root 3210215424 971796480 2238418944 31% / # ~~~ Calculating the space needed for the /usr/bigfile: ~~~ # echo $((2238418944-237072384)) 2001346560 # echo $((2001346560/1024/1024)) 1908 # dd if=/dev/urandom of=/usr/bigfile bs=1024k count=1908 1908+0 records in 1908+0 records out 2000683008 bytes (2.0 GB) copied, 104.975 s, 19.1 MB/s # df -B1 / Filesystem 1B-blocks Used Available Use% Mounted on /dev/mapper/rhel-root 3210215424 2972479488 237735936 93% / # ~~~ Making a little less space: ~~~ # dd if=/dev/urandom of=/usr/bigfile bs=1024k count=1909 1909+0 records in 1909+0 records out 2001731584 bytes (2.0 GB) copied, 104.584 s, 19.1 MB/s # df -B1 / Filesystem 1B-blocks Used Available Use% Mounted on /dev/mapper/rhel-root 3210215424 2973528064 236687360 93% / # ~~~ Trying to reproduce: ~~~ # yum update -y ... snip ...
