Error: Cannot set the effective uid to 0 due to incorrect ownership or nosuid mount on assrvc

Products

• Autosys Workload Automation

Issue/Introduction

When attempting to source environment variables or start services, the following error is received: ERROR - Cannot set the effective uid to 0. Please make sure "$AUTOSYS_CSUTILS/bin/assrvc" has Set-Uid permissions

Environment

• Workload Automation AE (AutoSys)
• Linux Operating Systems

Cause

The assrvc utility requires root privileges to function correctly. This error occurs if either of the following conditions is true:

1. Incorrect Ownership: The assrvc file is owned by a non-root user (e.g., the autosys user). On Linux, the Set-UID bit only grants root access if the file is owned by root.
2. Filesystem Restrictions: The filesystem where $AUTOSYS_CSUTILS/bin/ resides (often /opt) is mounted with the nosuid option, which prevents the execution of Set-UID binaries.

Resolution

Step 1: Verify and Fix File Ownership

1. Navigate to the utility directory:
   bash

   cd $AUTOSYS_CSUTILS/bin/

2. Check the ownership and permissions:
   bash

   ls -ltrh assrvc

3. If the file is not owned by root, change the owner and re-assert permissions:
   bash

   Note: ust be run as root
   
   chown root:root assrvc
   chmod 4755 assrvc

Step 2: Verify and Fix Filesystem Mount Options

1. Check the live mount options for the filesystem:
   bash

   findmnt -no OPTIONS /opt

   (Replace /opt with the appropriate mount point if different)
2. If the output contains nosuid, the filesystem must be remounted without this restriction. Consult your System Administrator to update /etc/fstab and remount the volume:
   bash

   mount -o remount,suid /opt

Step 3: Validation

Re-run the original operation. The command should now execute without the effective UID error
