Partitions not set up on ISO install - Docker Service not starting

Hello,

I am trying to install Zenoss CC and Core 6.2 on a vm from the ISO file:
zenoss-core-6.2.0-1-master.x86_64.iso

I am able to install the application on the vm but it will not display the browser interface for core-master. When I checked the journalctl I can see that docker.service failed to start and the reason is when it runs "docker-thinpool-check.sh" I receive the error "Volume group 'docker' not found".

I believe this is related to an error I get in the CentOS installation GUI on boot, under the section "Installation Destination" I get an "Error checking the storage configuration" which is "Unable to allocate requested partition scheme".

I believe I am giving my vm sufficient resources and space, it is running on a cluster and I allocated:
16 CPUs
32GB RAM
500GB Storage

Is there something I need to do to manually configure the partitions/volume groups so that docker.service can run?

Thanks,
Matt

Hi Matt

Normally not, but it depends on how you have set up your base system.

Can you poste the lsblk output and verify your storage configuration as described in section 3?

# lsblk -ap --output=NAME,SIZE,TYPE,FSTYPE,MOUNTPOINT

Hi Arthur,

Thank you for the reply.
My disk is not being allocated as described in section 3. The output of the lsblk command is as follows:

NAME                                                                          SIZE  TYPE  FSTYPE                   MOUNTPOINT
/dev/sda                                                                    500G  disk
├─/dev/sda1                                                                1G  part   xfs                           /boot
 └─/dev/sda2                                                             499G  part   LVM2_member
    ├─/dev/mapper/centos_core--master-root          50G  lvm   xfs                           /
    ├─/dev/mapper/centos_core--master-swap      15.8G  lvm   swap                      [SWAP]
     └─/dev/mapper/centos_core--master-home    433.2G  lvm   xfs                          /home
/dev/sr0                                                                   1024M rom

SOLVED:

I fixed my issue. Turns out the system needed 512 GB of storage, so once I allocated more space, it worked great. Missed it by that much!

Hi Matt

Great!
Just a small reminder. If this installation will become a productive one I would configure the disklayout as described in the document.

And another info from the document:
On vSphere hypervisors, the disks are created when the OVA is installed. On Hyper-V hypervisors, the disks must
be created manually.

Cheers
