DXO2 26.1 HF2 installation fails on pre-upgrade phase.

Products

• DX Operational Observability

Issue/Introduction

During the hot fix 2 installation on DXO2 version 26.1, the Helm upgrade process fails during execution of the pre-upgrade hook.

The console output reports the following error:

Error: UPGRADE FAILED: pre-upgrade hooks failed: 1 error occurred:
        * pod ###-pod failed

Cause

The ###-pod is executed prior to the main upgrade steps to validate and prepare shared persistent storage directories. This pod fails to initialize or complete when there are underlying environmental issues with the NFS volume mounting oishared, including:

• Filesystem corruption or bad blocks on the NFS storage target.
• Damaged file system pointers or directory tree structures.
• Stale mounts, improper locking, or read/write I/O errors on the NFS share.

Resolution

Check the NFS host server and system logs (/var/log/messages, dmesg) for I/O errors, block allocation failures, or bad sector warnings. 

Run a filesystem integrity check to detect and fix structural damage or corruptions.

Once the NFS filesystem issues are resolved, re-trigger the Hot Fix 2 upgrade command.
