Hai,

Thanks for a quick response.

- what do you mean by "disks are not added"? Does the server recognize
them? Do you see them in the output of "lsblk"?
Server does not add them automatically, I tried to mount them. I tried they
way they discussed in the page with /dev/sdb only. Other hard disks I have
mounted them my self. Yes I can see them in lsblk output as below

- Do you already have existing physical volumes for cinder (assuming you
deployed cinder with lvm as in the provided link)?
Yes, I have tried one of the HD (/dev/sdb)

- If the system recognizes the new disks and you deployed cinder with lvm
you can create a new physical volume and extend your existing volume group
to have more space for cinder. Is this a failing step or someting else?
System does not recognize the disks automatically, I have manually mounted
them or added them to cinder.

In Nova-Compute logs I can only see main hard disk shown in the the
complete phys_disk, it was supposed to show more  phys_disk available
atleast 5.8 TB if only /dev/sdb is added as per my understand (May be I am
thinking it in the wrong way, I want increase my compute node disk size to
launch more VMs)

2018-08-08 11:58:41.722 34111 INFO nova.compute.resource_tracker

- Please describe more precisely what exactly you tried and what exactly
fails.
As explained in the previous point, I want to increase the  phys_disk size
to use the compute node more efficiently. So to add the HD to compute node
I am installing cinder on the compute node to add all the HDs.

I might be doing something wrong.

Thanks and Regards,
Jayachander.
