vCenter running on low disk space, how to fix this?

vCenter server low disk space.


To Fix the issue by expanding the corresponding VMDK of vCenter, please follow these steps:

This issue could prevent you from being able to log into vCenter at all.




  • Log into vCSA via SSH.
  • List the partitions by running the following command: df –h
  • You will be able to see the affected partition/disk as shown below.

003 vcsa


  • Look up the corresponding VMDK file from the following table:


VMDK1 12GB / (10GB)
/boot (132MB)
Boot directory where the kernel images and boot load configurations go
VMDK2 1.3GB /tmp Temporary directory used to store temporary files generated or used by services from vCenter Server
VMDK3 25GB SWAP Swap directory used when the system is out of memory to swap to disk
VMDK4 25GB /storage/core Core directory where core dumps from VPXD process from the vCenter Server are stored,
VMDK5 10GB /storage/log Log directory where vCenter Server stores all logs for the environment
VMDK6 10GB /storage/db VMware Postgres database storage location
VMDK7 5GB /storage/dblog VMware Postgres database logging location
VMDK8 10GB /storage/seat Stats, Events and Tasks (SEAT) directory for VMware Postgres
VMDK9 1GB /storage/netdump VMware Netdump collector repository that stores ESXi dumps
VMDK10 10GB /storage/autodeploy VMware Auto Deploy repository that stores the thinpackages used for stateless booting of ESXi hosts.
VMDK11 5GB /storage/invsvc VMware Inventory Service directory where the xDB, Inventory Service bootstrap configuration file, and tomcat configuration files reside.



  • In our example, the corresponding VMDK is VMDK5.
  • Edit the VCSA VM configuration and extend the VMDK to a desired size.
  • Now, expand the partition from within the VCSA by running the following commands:

shell.set –enabled true
vpxd_servicecfg storage lvm autogrow


or just reboot VCSA.

Disk expansion is much easier than deleting the content data.

  • Now, run df-h again and see that the size has changed.

And also the health status of VCSA has changed to “Good”.
