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

[Gary S. Cuozzo]

Assuming there is space left in the LVM VG, you should be able to use lvextend to add a bit of extra storage to that volume so the deployment can succeed. Something like 'lvextend -L + 100M <dev of lv>' 

Hope that helps, 
gary

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
