Error: rpmdb open failed

Environment

• Platform9 Managed OpenStack - All Versions
• Platform9 Managed Kubernetes - All Versions
• CentOS

Cause

• One or more partitions on the root disk are full.
• The Yum database is corrupted on disk.

Resolution

1. Check the disk utilization on the host.

# df -h

2. If one or more partitions are full, identify where space is being utilized and clear the necessary amount of disk space so that the Platform9 components may continue to function.

# du -h /partition | sort -h

3. If there is a sufficient amount of disk space available (<97%) on all of the root disk partitions and yum commands fail with the same error, the package database may need to be rebuilt.

# rpm --rebuilddb

4. Restart the pf9-hostagent service.

# systemctl restart pf9-hostagent
