WHM 11.46 Upgrade failing - /usr directory running out of space

When both of my servers try to upgrade to 11.46 they run out of space in the usr partition (it slowly climbs up to 100%) and then fail.

The end of the update logs contain a bunch of errors like this:

[20141109.230200] installing package cpanel-bootstrap-devel-3.1.1-2.cp1142.noarch needs 83MB on the /usr filesystem
[20141109.230200] installing package cpanel-perl-514-Math-Permute-List-1.004-1.cp1146.x86_64 needs 83MB on the /usr filesystem
[20141109.230200] installing package cpanel-perl-514-Cpanel-Class-v1.0.6-1.cp1146.x86_64 needs 83MB on the /usr filesystem
[20141109.230200] installing package cpanel-perl-514-Config-Simple-4.58-1.cp1146.x86_64 needs 83MB on the /usr filesystem

Both servers have over 2gb free in the /usr partitions when the upgrades start:

/usr 73% (7,026,840 of 10,154,020)

/usr 71% (5,789,932 of 8,123,200)

Any ideas? The script obviously thinks they have enough space to begin the upgrade, or it would fail before it even started the process.

Hello :)

The output you provided indicates /usr partitions with around 10G and 8G overall size. Per our documentation, it's advised to have at least 16G for /usr if you use advanced partitioning:

Advanced Partitions

However, it's a common mistake to setup separate partitions when you don't really need to. You can review the recommended partition setup here:

Configuring OS Before Installation

As far as your current issue, check to see what's taking up most of the space on /usr to see if any of it is removable or able to be moved to another partition.

Thank you.
