Hi, first of all it would be nice to know what version of opennebula are u using.
This error has to do with the stat operation (vcenter driver), you may take a look to your oned.conf and find the same line with the command fail execution.
When you has done this, execute the command stat by yourself (copying command fail line), this will give us a verbose output.
First of all I will thank you Sergio. You helped me a lot.
So after upgrading to version 5.4.1, I changed the name of the datastore as you suggested and then I imported it with OpenNebula. My error disappeared but another was now displayed:
Not enough space in datastore
While I had about 30 Giga then I saw on a forum this solution:
It actually works !
The question is : Why OpenNebula is complaining about there is not enough space available in datastore when there is enough space ?
About your datastore problem, are you sure about this? i guess that opennebula datastore monitoring is working fine, in one of the screen that u posted here it was easy to see that you had space problems (0 % available).
mmm if the datastore poll monitoring says these information it should be true and if not it might be a bug so keep me informed about this if u face the same issue again.
