[one-users] Fwd: No space left on device ->when Create Image via Marketplace for CentOS 6.2-kvm using iSCSI (block) datastore

[Ruben S. Montero]

Hi,

This is a known issue when using the market place with block based
datastores, see [1].

The size of the image is get from the ContentLength header field (HTTP)
using the marketplace URL. This size is for the compressed image, so the
actual size of the block is not properly configured. Also the usage quotas
will not be properly updated...

Probably we either set contnent lenght to the uncompressed size, or provide
an additional header for it. The requirement here is not to download the
full image to get the size. The download, uncompress, write process is
"streamed", so we need the size beforehand.

Cheers

Ruben
