• Checking the disk space on the sddc manager with the following command df -h shows full:

 

Environment

SDDC Manager 9.x

VCF 9.x

Cause

The filesystem hosting the UMDS patch store (typically an NFS mount or local directory at /nfs/vmware/vcf/nfs-mount/umds/patch-store) has exhausted its available disk space, preventing the download service from writing version metadata or new patch binaries.

Resolution

• Log in to the SDDC Manager appliance as vcf and switch to root.

• Verify disk usage of the nfs-mount:

       du -sh /nfs/vmware/vcf/nfs-mount/* | sort -h

• Identify and remove unnecessary items such as backups or older patch bundles to free space
