trying to upload template, getting 'cp ... failed with exit code 1'

[joeblow]

I'm trying to upload an appliance template via the proxmox web page. It fails with the error:

Error: command 'cp /tmp/proxmox_upload-6495.bin /var/lib/vz/template/cache/centos-5-standard_5.6-1_amd64.tar.gz' failed with exit code 1

This is repeatable, and using other templates gives the same result. As a side note downloading templates using the download tab is successful.

Any thoughts?
