Hi,
I have tried to upload an image with the following commands:

euca-bundle-image -i olio-f17_64-xen.img -u mex

euca-upload-bundle -b mexBucket -m /tmp/olio-f17_64-xen.img.manifest.xml

euca-register mexbucket/olio-f17_64-xen.img.manifest.xml

but in the last 4 days i got "untarring" as status of my image:
[mex at minicloud cred]$ euca-describe-images --debug ami-00000004
IMAGE   ami-00000004    
mexbucket/olio-f17_64-xen.img.manifest.xml              untarring       
private         x86_64  machine               instance-store

In the ML someone tells to check at the diskspace, but It seems that is 
not my case:
[mex at minicloud cred]$ df -h

/dev/sda5       192G  148G   34G  82% /home

Where has the image being uploaded?

Any suggestion for this problem?

After this problem, all new request for instances stay in "pending" 
status forever.

Thanks for your time,
