Solution 2353380.1 : root filesystem of Infiniband Switch reached to 94%

Applies to:

Sun Datacenter InfiniBand Switch 36 - Version All Versions and later
Sun Network QDR InfiniBand Gateway Switch - Version All Versions and later
Information in this document applies to any platform.

Symptoms

root filesystem of Infiniband Switch reaches 94%

Changes

After upgrading to firmware version 2.2.X, the Infiniband Switch root filesystem reaches to ~94% - 95%

Cause

With firmware versions 2.2.x the Sun Datacenter InfiniBand Switch 36 and Sun Network QDR InfiniBand Gateway Switch, the firmware has moved to Oracle Linux 6 as the base OS (from CentOS 5.2 for firmware 2.1.x and earlier), and the new OS uses more space than the older. This said, configuration and logs are on other partitions of the SSD, so the root partition will not grow.

This change can be verified in Read Me file for the Patch "Moved From CentOS 5.2 to Oracle Linux 6.5 with UEK2" under Changes from version 2.1.8."
