[one-users] Old Vms directory not deleted - DB compromised

[Duverne, Cyrille]

Hello Carlos,

Thanks a lot for your feedback.

Regarding the Hooks, it works like a charm.
But you said that it was normal to not delete the old directory of
destroyed VMs, why ?

Regarding the reserved image, I haven't any VM in any state which is
using it... :)

Kind regards
CyD

I've seen this behaviour in 3.2, but it's still happening in 3.8

The VM dirs are left behind, that's normal. You can clean-up them
using hooks [1], take a look at this ticket [2].

VM_HOOK = [
   name      = "vmdir_cleanup",
   on        = "DONE",
   command   = "/bin/rm",
   arguments = "-r /var/lib/one/$VMID" ]

VM_HOOK = [
   name      = "log_cleanup",
   on        = "DONE",
   command   = "/bin/rm",
   arguments = "/var/log/one/$VMID.log" ]

In previous versions the dirs would be recreated, but it should work
in 3.6.

By the way, where did you get opennebula 3.8? Can I take a look at it?
That will speed development! :-)

And on another side, I have an image that can't be deleted, Sunstone
says that it's used by 4 VMs, but none is running, and the image can't
be deleted from the DB I think.

The Image can still be reserved for VMs in states other than running,
like stopped or suspended.
Is this your case?

Hi,

The files should have been deleted. Do you have any error messages in
/var/log/one/oned.log?

You can also check each image file path using 'oneimage show', it's
the SOURCE attribute.

 Hello,

my hard drive is running out of space. So i deleted some unused images
in Opennebula via the sunstone gui.
But i didn't get any additional free hard drive space. But the
datastore contains only files with hash names.
Why happen this? Is this a bug or a feature?

Regards,

Christoph Robbert
