[Ricardo Duarte]

Hi Jaime,

Will 3.8.1 be available as OpenNebula, or OpenNebula Pro?

Regards,
Ricardo

Hi,
In ONE 3.6 if you resume a VM and it doesn't work, it will go into FAIL, and once it's in fail you cannot bring it back to RUNNING again.
I suggest you upgrade to 3.8.1 (not 3.8.0) so you don't risk losing VMs.


We're about to release 3.8.1 (couple of hours luckily) which fixes a bug that affects VMs with CONTEXT
cheers,
Jaime

Hi Jaime,  Thank you for the prompt response. I have a optic fiber multipath disk shared with NFS to datastore and my images are very heterogeneous. I've started to stop the 69 VMs page by page (10 at a time), and it is working fine. I'll shutdown ONE 3.6 and Sunstone also.

Hi,
It really depends on your storage configuration.
If you are using TM SSH (or using SHARED and all your VMS are CLONE = YES => images: persistent => no) AND you are *not* moving your system datastore, just the regular datastores, then you can just stop opennebula during the operations so no deploy or shutdown/save is performed in the meantime. 






Otherwise,  to be on the safe side I recommed you stop the vms and shutdown OpenNebula.
cheers,Jaime

Hello again,

 My LUN disks, where datastore is located, are being moved to other physical location. What is the best way to prepare this migration and all VMs startup smoothly after remounting the disks? 



 Shutdown all VMS and restart them after?Shutdown ONE main host/frontend blade?Other? --André Monteiro
