Re: [one-users] Removing old VMs

2012-04-18 Thread Ruben S. Montero

Hi,

The re-creation of VM directories should be fixed in 3.4. So the original
proposal (hook with rm  VM directory) should now work. Have you tried that
in 3.4?

Cheers

Ruben

2012-01-18 Thread Carlos Martín Sánchez

Hi,

I think the best way to solve it is to add some configuration option to
purge all VMs that reach the DONE state, deleting them from the DB and the
filesystem. This would break the accounting, however.

We will consider this for next versions, thanks for your feedback.

Re: [one-users] Removing old VMs

2011-12-20 Thread Hutson Betts

I needed to forward this to the listserv.

Also, on the same note, I discovered another odd behavior:

Several VMs have been deleted, their state is DONE, and I manually
removed their folders. However, when I issue a 'show' command to view
information for VMs that have transitioned to the DONE state, a folder
is created for them. What's odd about this behavior, is that it only
occurs the first time I issue the 'show' command. Issuing that command a
second time does not re-create the folder.

oneadmin@opennebula-server:~$ ls
auth  config  images  oneacct.db  one.db  onequota.db  remotes

This makes the clean-up scripts potentially worthless since VMs within
the database can cause changes to content within the file system, and no
hook can resolve that.

For my network policy, a simple clean-up hook is sufficient to remove
files and folders that will no longer be needed. However, in the future,
some method to purge even the database would be nice. Maybe:
'onevm purge-done' (Or something...)

Re: [one-users] Removing old VMs

2011-12-20 Thread Carlos Martín Sánchez

Hi,

The feature request #1026 [1] can be easily implemented with hooks [2].

For instance, with these two hooks you don't even need any script file:

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" ]


If you want to create an external script, please take into account bug
#1036: Local hooks are not executed unless the full path is defined.

That means that this hook won't be triggered:

VM_HOOK = [
   name  = "cleanup",
   on= "DONE",
   command   = "cleanup.sh",
   arguments = "$VMID" ]


And you must use this one instead:

VM_HOOK = [
   name  = "cleanup",
   on= "DONE",
   command   = "/full/path/to/cleanup.sh",
   arguments = "$VMID" ]

Cheers.

This does not answer my question.
I don't have a fixed set of VMs.

Especially the directories in /var/lib/one/ are nasty.




Two ways--
Either don't use the "SAVE" option in your template

or

use VM's from the image repository and then opennebula
will save them back to the image repository instead of the
/var/lib/one/directory.

Re: [one-users] Removing old VMs

2011-12-15 Thread Hutson Betts

Dear Richard,

This is not necessarily an answer to your question, but if you'll
consider taking a look at Feature #1026 that I created on the dev site.

I can understand that all reference material associated with a VM would
remain even when the VM is in the "DONE" state since technically that is
an acceptable state for the VM to exist. There could exist a scenario
where the user would like access to deployment files, logs, etc.

However, it would be nice if there was a method to clear-out all data
related to VMs. That's where Feature #1026 comes in. Currently, even
deleting a VM leaves all its files laying around.
