vCenter Server /storage/seat Partition Reaches 100 Percent Capacity Exhaustion

Products

• VMware vCenter Server

Issue/Introduction

vCenter Server Appliance (vCSA) File system storage/seat for the database has run out of space. Review of the appliance storage indicates the SEAT partition is completely exhausted. Terminal output for df -h confirms the /storage/seat partition is at 100% capacity (61G used of 64G allocated).

Environment

VMware vCenter Server Appliance 8.0.x

Cause

The virtual disk backing the /storage/seat partition has reached its maximum allocated capacity, preventing the database from writing new data and disrupting vCenter services.

Resolution

 

1. Log in to the vSphere Client or ESXi Host Client and increase the Provisioned Size of the virtual disk backing the /storage/seat partition.

2. Connect to the vCSA via SSH as root.

3. Execute vpxd_servicecfg storage lvm autogrow to expand the guest OS logical volume to utilize the newly added disk space.

4. Verify the space is successfully reclaimed using df -h.

5. Start all vCenter services using service-control --start --all.

NOTE:

• If extending VMDK size option is greyed out, the disk may be running on snapshots, or the disk may be at the maximum allowed size depending on the block size of the datastore. Remove any snapshots attached to the vCenter VM before progressing and ensure a full file-level backup of the vCenter before extending any partitions.
