What is the minimum kernel needed for Portworx?
Comprehensive and Detailed Explanation From Exact Extract:
Portworx requires a minimum Linux kernel version of 3.10 or greater to operate properly. This requirement stems from Portworx's dependencies on certain kernel features and modules that became standard from kernel version 3.10 onwards. The kernel version affects support for device-mapper, overlay filesystems, network stack enhancements, and other low-level capabilities essential for Portworx's block storage functionality and performance. Although newer kernels (like 4.15+) offer additional features and improvements, Portworx maintains compatibility back to 3.10 to support a wide range of enterprise Linux distributions such as RHEL, CentOS, and Ubuntu LTS releases. The official Portworx system requirements document explicitly states kernel 3.10 as the minimum supported version to ensure stability and compatibility in production environmentsPure Storage Portworx System Requirementssource.
