Hi all.
I'm using CS4.1 with KVM and CentOS 6.4.
When trying to download a volume of a VM from the GUI everything seems
to go ok and I get to see a message with a download URL. But when trying
to use it I get the message:"The requested URL
/userdata/cd0f3ceb-5925-4641-bdcb-770f029275f8cow2 was not found on this
server."
Looking through the management server log I see (only relevant parts shown):

What I get from that is thet the volume is correctly copied from primary
to secondary storage and the the creation of the download link fails.The
problem seems to be that there is no space left, but both my primary and
secondary storage have plenty of space left. And apart from this
everything else is working in my cloud: VMs, snapshots, consoles, ISOs,
templates, etc.
Any pointers of where to look next will be greatly appreciated.
Thanks.
