Hello

I have installed PACKSTACK queens version in two servers with the time the memory is low and I have added more memory to the servers.

I have followed this documentations: https://docs.openstack.org/cinder/pike/admin/blockstorage-multi-backend.html#enable-multiple-storage-back-ends (https://docs.openstack.org/cinder/pik...) https://docs.openstack.org/mitaka/install-guide-rdo/cinder-storage-install.html (https://docs.openstack.org/mitaka/ins...) https://docs.openstack.org/cinder/pike/admin/blockstorage-multi-backend.html#top (https://docs.openstack.org/cinder/pik...)

In Horizon, the hipervisor have not updated the local storage parameter.

How can I add news HDD to my openstack (Packstack queens version)? Thank you very muchs. Best regard.

Do you want to increase volume storage or hypervisor storage? Or both?

By default (and I think Packstack uses the default), hypervisor storage is under /var/lib/nova/instances on compute nodes. If you don't add storage there, it has no effect on the hypervisor.

I have added 16 TB of physical memory, I want the openstack to recognise this capacity in hypervisor. because I need to create a virtual disk 1TB of capacity

Could I create a /dev/loop partitions on the DISK? or you recommend another solution better

I have mounted the HDD in /var/lib/nova/instances. The hipervisor shows the expected local storage space. 2TB to 30TB

I have tried to create an instance and I got the next error:

Mensaje Build of instance 1ad33da4-b874-4acb-b27d-6a1adcbf393b aborted: Volume a7ce159d-ac9c-4d57-a068-0a972b85cc14 did not finish being created even after we waited 12 seconds or 5 attempts. And its status is error.

Can someone help me??

This instance has a volume as storage, and this volume is not created in time or not at all. Check the Cinder logs.

By the way, you have a better chance getting answers when you create a new question instead of an answer to an old question.

Try to increase the volume creation timeouts in nova.conf (compute), the default won't suffice for such large volumes. Check the values for block_device_allocate_retries, block_device_allocate_retries_interval and block_device_creation_timeout. Increase them and restart the nova compute.

why does openstack not create the instance?

I am going to try eblock solution
