As i know the 5.6 version is in short term support.
Now i'm deploying a two Oracle 12c RAC clusters on 2 8000 6-nodes AOS-AHV clusters with AOS 220.127.116.11.
It involves using volume group with multiple vdisk, network related configuration, Linux related tuning and so on...
Of course, with 18.104.22.168 (so far the latest GA version in long term support), i've not the VGLS choice, every volume group's I/O is managed by a single CVM.
By the other side, with AOS 5.6, i could distribute this load on every single CVM and every single node storage on the cluster.
Of couse this heavily impact on the resiliency, the performance and the resources distribution.
The questions are two and i need some suggestions.
1) could be better to upgrade to 5.6 even if it is in short term support?
2) is it possible to update "on the fly" the volumes's configuration with "vg.update load_balance_vm_attacchments" or i should recreate che volumes? (is there a third shot or other related procedures?)
Thank you all so much
