Description
Dear node team,
FRACTALS accelerator team has contacted us for one fo their subgrantees (the EMPORIA project)
.
Mr. Ververidis has lost access to his instances since PireausN node has shutdown.
He has filled the migration form. It seems he requested to move to PireausU node. Could you kindly help this SME?
Thanks,
ilknur

Activity
Dear ilknur,
the previous week we started the migration of the VMs from PiraeusN node to PiraeusU node. This process was implemented by using VM snapshots of the guest VMs that belong to the users. The snapshots were stored in our glance registry. We managed to store 8 different VM of 3 different user tenants. The node glance do not have further storage space and for this reason we have temporarily freeze the migration process.
The process could be gradually completed if:
- the tenants that already migrated in PiraeusU node instantiate their VM from the stored snapshots and then inform us so as to remove from the glance the corresponding snapshot so as to get some free space and then to migrate the rest of the VMs. We have already inform the migrated tenants to proceed with this process but we don't have some information so far. We could send a new email to each tenant so as to advice to proceed with the above process so as to help the other tenants to be migrated.
In addition, we try to add a new VM that will support a NFS tha will be mounted on the existing glance store of our node. Till now we did not managed to achieve this extension. However, we are working so as to achieve it.
To our personal view a potential solution would be to migrate the rest of the VM snapshots that cannot be deployed on PiraeusU node, to another node with more available resources so as to avoid potential delays for the end-users/tenants. Would it be feasible?
Best Regards,
PiraeusU node team
Dear Gergő,
It seems that releasing the IPs and allocating new ones from
public-ext-net-01 solved the problem.
We have managed to initialize the emporia-authz and the emporia-poi
instances successfully and are trying to connect via ssh to the others but
have not managed yet (it could be our internal issue and we are working to
figure it out now).
Best,
Christopher
