QUESTION
Is there an elegant way to copy an RBD volume to another Ceph cluster?
I calculate the convert time with qemu-img 2.5 version or qemu-img 6.0 version, by copying a volume(capability is 2.5T and 18G only used) to another Ceph cluster.
...ANSWER
Answered 2021-Apr-19 at 05:55The main feature is qemu-img convert -n the -n option parameter.
If convert the disk with '-n' skips the target volume creation (useful if the volume is created prior to running qemu-img) parameter, it will write the hole disk capability to the destination rbd volume. Without it, the qemu-img convert only read the source volume used capability and write them to destination volume
QUESTION
Hello guys and I hope you're having a great day. I have a question about using Openstack API in Python.
I'm using python-novaclient for getting server details and flavor details. And I want to get the volume details too but I don't know how to do it, I've tried to collect volume details but it failed somehow and I need to ask you guys if you have any idea.
This information is what I want to get:
volume_id, attached to (w/c volume), name, status and volume_type (CEPH or LVM)
I used python-cinderclient, but I only got the volume_id.
Here's the code:
ANSWER
Answered 2021-Apr-01 at 10:09I've finally figured it out, and I'm going to answer this for anyone who is interested in Openstack SDK or other Python API for Openstack.
First, for authentication you need to use Keystone API, the documentation is all over the internet so no need to worry, you could just oversee in your Openstack for credentials needed. And for my question, I use the function get_volume from Connection class. Please see the documentation
for this. You can read other documentation as well on the internet.
So, here is the example of how to get volumes details:

QUESTION
after few deployment of openstack (packstack all-in-one) I founded that (from hypervisor summary) the local storage size is around 40G-50G. The disk storage that I deployed is actually around 150G and 250G but keep getting around 40-50G in openstack. The same behavior when I run over VM and baremetal. During OS(Centos7) installation I just using default auto setup...all storage size (sda) and never set manual. For example this is the VGS output from VM with 150G storage running openstack
...ANSWER
Answered 2020-Oct-16 at 05:19What do you mean by storage size? If you mean the amount of storage for Cinder volumes, adjust the CONFIG_CINDER_VOLUMES_SIZE parameter. The documentation isn't clear about it, but I think the number is in Gigabytes. However, this only works if your root filesystem has enough space.
If you mean ephemeral storage, you also need to have a root filesystem that is large enough. I see that your system has three LVM volumes for root, swap and home. My suspicion is that your root volume (named centos-root) is too small. If that is the case, create a Centos installation that does not separate root and home and try again.
Adding additional information to answer the below questions:
The storage size reported in the hypervisor summary refers to the space available in Nova's instances directory, probably under /var/lib/nova (not sure). Which is on your root filesystem.
Packstack uses an LVM volume group as the storage backend for Cinder. The physical volume for that volume group resides on a loop device /dev/loop1, which is a file that resides on the root filesystem. Therefore, Cinder's storage does take up space in your root filesystem. Use the command losetup -a to see that file.

QUESTION
In my statefulset I defined volumeClaimTemplates. Added definition of storageclass. After deployment I have PVC, PV and SC created. Reclaim policy is Delete. However after performing helm delete <> --purge all resources are deleted except PVC's
I use kubernetes.io/cinder for dynamic provisioning.
Below pvc
...ANSWER
Answered 2020-Sep-24 at 08:06According to https://github.com/helm/helm/issues/3313 this is working as intended because the PVCs got created by the statefulset and not helm itself.

Install cinder
You can use cinder like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
