Error when installing ubuntu18 on dashboard is "you need 8.6 Gb for this installation you have zero space for this system”
I Install openstack queen on server using KVM. I have 3 nodes controller, compute and storage. I follow this tutorial. Now every thing install correctly i check all the status like neutron,nova etc, all are active.On dashboard i am creating ubuntu18 ISO image its create now when i launch an instance and install ubuntu it will give me space error that you have zero space to install this you need 8.6 GB for this installation so what is the issue if someone tell me . How i can check the image path that ubuntu image installed and how i can give space to that image.
Whivh tutorial do you mean?
I understand that you launch an instance from an ISO image and get this message when trying to install the ISO.
Did you add another disk? If not, the instance has only a DVDROM and no storage to which it can install Ubuntu.
@Bernd Bausch, You mean flavor?? I already add a flavor when creating instance How can I add another disk ?? I already search a lot on the internet but not succeed.
And I follow this tutorial https://docs.openstack.org/install-guide/ (https://docs.openstack.org/install-gu...)
I don't understand what you are doing. What are your instance launch parameters?
You add a disk by attaching a volume.
OK i will tell you i am installing open-stack queen on single machine with KVM. In KVM i have 3 nodes controller,compute and storage but i have configured controller and compute node completely now using dashboard i am creating instance i have Ubuntu ISO image in dashboard.
Again: What are your instance launch parameters? What image, storage, networking, flavor etc do you use? I still don't understand how you launch the instance.
can you give me your email address i will give you detail with screenshots ..??
It should not be too hard to describe the instance parameters. Image, flavor, volumes (if any).
Do you want to create an image by booting from an installation ISO? See https://help.dreamhost.com/hc/en-us/a....
I understand what you say first I need to attach volume then trying to launch an instance and install ubuntu desktop, after that what results it gives me I will tell you just give me any tutorial that how I can configure storage node for OpenStack queen installation in ubuntu16 Thanks
No. You attach the volume after launching the instance. See the Dreamhost tutorial.
Installing Cinder for Queens: https://docs.openstack.org/cinder/que....
Yes I know it's my sentence mistake obviously volume attach after launching the instance. Sorry for this actually i am trying to write this i need to configure cinder first
Obviously, I know volumes attach after launching the instance actually I want to write this "I need to configure volume" anyway I got it your point
@Bernd Bausch, now I am configuring cinder-volume, I install LVM but my question is how I can configure LVM in KVM guests because I have a partition with /dev/vda on my KVM guests so can you clear this concept of LVM when configuring in KVM..??
You configure LVM in a KVM guest in the same way as on a physical server. Get yourself a disk (in OpenStack: A volume), pvcreate, vgcreate, lvcreate.
But I am facing error when running this pvcreate /dev/vda1 command it gives me this error
root@storage:~# pvcreate /dev/vda1
Can't open /dev/vda1 exclusively. Mounted filesystem?
My disk partition in object storage node looks like this :
root@storage:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sr0 11:0 1 1024M 0 rom
vda 252:0 0 300G 0 disk
├─vda2 252:2 0 1K 0 part
├─vda5 252:5 0 975M 0 part [SWAP]
└─vda1 252:1 0 299G 0 part /
root@storage:~# lvmdiskscan /dev/vda1 [ 299.04 GiB] /dev/vda5 [ 975.00 MiB] 0 disks 2 partitions 0 LVM physical volume whole disks 0 LVM physical volumes
Yes, vda1 is mounted. It’s your root filesystem.
I think you want to attach a volume to the instance and create a physical volume on it. I am not quite certain if I understand your ultimate goal, though.
Now I am totally confused. What does the object storage node have to do with a KVM guest?
I think you want to attach a volume to the instance I just follow the tutorial that you gave me for cinder configuration and on this tutorial, it configures the physical volume my aim is to solve the error that I mentioned before. To solve this issue we discussed that we need to configure cinder
Don't be confused it's very simple that I already mention is that I follow the tutorial and for cinder configuration I need other VM that is object storage node and simply I am configuring
The tutorial doesn’t mention an object storage node. And it saysCreate the LVM physical volume /dev/sdb. You need a second disk.
On the top, it mentions that Perform these steps on the storage node. what does it mean..??
