[all][stable] Propose to EOL Pike series
by Előd Illés 29 Jul '22

29 Jul '22

Hi, It seems that time has come to (mass)transition Pike to End of Life due to lack of maintainers (and backports + reviews; see the list of recent changes [1]). Some core projects have made this step already. Others are still open but not really maintained, which can be seen by the number of daily periodic stable job failures on pike branch, which is around 40 for several months now. (By the way, periodic stable job failures number is constantly high [2], due to some projects which seem to be abandoned completely (murano, *-powervm), but that is another story). Please let me know what do you think, or indicate if any of the projects wants to keep its pike branch open / in Extended Maintenance.

hi Team, There is a use case, where a user wants to Create CI/CD pipeline using Application Credentials of Open Stack, Henceforth we tried Create an application with a role with a secret Key. but it is failing with the below output, The user wants to push the qcow2 image from his system to Open Stack. Using auth plugin: v3 application credential /usr/lib/python3.7/socket.py:660: ResourceWarning: unclosed <socket.socket fd=3, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6, laddr=('172.17.0.3', 55738), raddr=('10.188.2.9', 5000)> self._sock = None ResourceWarning: Enable tracemalloc to get the object allocation traceback Not Found (HTTP 404) (Request-ID: req-217c9f28-d6a6-4649-adf9-2d9a4b965b3f) END return value: 1 it failed with a below result Regards Adivya Singh

Manila/NFS support for Zun
by Vaibhav 28 Jul '22

28 Jul '22

Hi, I want to mount my Manila shares on containers managed by Zun. I can see a Fuxi project and driver for this but it is discontinued now. I want to have a shared file system to be mounted on multiple containers simultaneously, it is not possible with cinder. Is there any alternative to Fuxi? Or can it work with yoga release ? Please advise and give a suggestion. Regards, Vaibhav

RAM and Storage requirements for Openstack cloud
by Mahendra Paipuri 27 Jul '22

27 Jul '22

Hello all, We are going to deploy Openstack cloud with researchers as primary target users. We will have around 100 GPUs with 12-15 servers with Infiniband interconnect. We still do not know the exact spec of servers nor GPUs but mostly we will have A100s and Intel Xeon processors. What sort of RAM and Storage requirements we need for a cluster of this size? Of course, this depends a lot on use cases and this cloud will be primarily used for HPC and AI. For the storage, we are mainly interested in the block storage requirements for provisioning VMs. We will most probably have a shared parallel file system as scratch and project spaces. Is there any rule of thumb to get to the RAM and storage requirement numbers based on compute infrastructure we will have? If we can estimate a sort of "lower bound" that would be really helpful for us. If anyone have clusters of this size at your organizations and if you can share the RAM ans storage details of your clouds, that would be very useful for us too. Thanks a lot and have a great day!! Regards Mahendra

Customization of scheduler manager
by Levon Melikbekjan 27 Jul '22

27 Jul '22

Hi all, as part of my thesis, I modified the Openstack version Train with the intention of sharing resources, which are not in use with other users to ensure maximum utilization. So far everything is working fine except for the last step. Let me first explain my work. The system works according to the following rules: 1. Users who own compute hosts within the private cloud have the highest priority on their hosts. 2. Users who do not own hosts within the private cloud are low priority users who can instantiate their virtual machine on unused resources (on the hosts that have an owner). 3. If the owner wants to use his resources that are currently occupied, the foreign VM must be suspended to free up resources for the owners VM. 4. An owner is a low priority user on foreign hosts. Everything works automatically and generically, but in step 3 I do not suspend those VMs, I delete them. I want the VMs to be suspended to be able to restart them with the intention of being able to continue processes that are paused, and I know there is maybe a REST API functions that provides this functionality. A user should be able to continue his work after resources become free again. It would be annoying if long-running processes were killed. My question is this: Is the suspend function the right choice? Are the resources released when I use the suspend function? Thank you & Best regards, Levon Melikbekjan
