[one-users] Problems to delete image completely

[Carlos Martín Sánchez]

Hi Christoph,

It may be a bug in the core, but probably what is happening is that some DB
writes are failing. Do you have any related error messages in oned.log?

When checking these kind of problems, you should be aware that one* list
gets the information directly from the DB, and one* show gets the
information from the oned daemon cache. If there is any inconsistency,
things went wrong.

You can stop opennebula, and then remove the row with oid 292 from the
image_pool table.

Now, I have another problem with another image: I made an image

The fsck tool [1] should fix that. Stop opennebula, run fsck, and it will
fix the Image state.
