## Problem

1135782:smarta-saw-con-0 pod failed to be up during Patch Upgrade

![](attachments/688996417/688996416.png)

## Cause

The root cause is that during the drecompact process, the patch upgrade caused a restart, which interrupted the drecompact.

The next attempt to restart the drecompact failed, resulting in an infinite restart.

## Solution

**Option 1**: A notification will be created to ask the SaaS team to stop the daily drecompact before the upgrade process. (SaaS team experts may take some efforts to stop/start them for upgrade everytime)

**Option 2:** Use the workaround: We restore the smart-saw-con-0 pod data from its mirror pod smarta-saw-con-a-0, restart them, and then everything is working to normal. (Base on SaaS operation experience, we never meet this issue before. So, SaaS team experts only need apply it once we meet this issue.)
