This resolves #4 . Needs review

Issue with Cluster 1. Available storage = 100GB, not 133GB. It looks like there is 30% added?

How many nodes are available ?:  7
What hosts will be used for application storage (IP/FQDN) ?: aaa.com bbb.com ccc.com ddd.com
What are the raw storage devices for these hosts(/dev/<device>) ?: /dev/sdb
What is the size of each raw storage device (GB) ?: 100
What is the size for the registry persistent volume (GB)?: 10
How many replicas for logging ?: 50
What is the size for each logging persistent volume (GB) ?: 3
What is the size for each metrics persistent volume (GB) ?: 20
What hosts will be used for CNS logging + metrics backend storage  (IP/FQDN) ?:  fff.com ggg.com hhh.com
What are the raw storage devices for logging + metrics backend on these hosts (/dev/<device>) ?: /dev/sdb
What is the size of each raw storage device (GB) ? : 100

# * 
# Cluster 1
# Total Storage allocated (GB) = 0
# Total Storage available (GB) = 133
# Cluster 2
# Total Storage allocated (GB) = 231
# Total Storage available (GB) = 100

The 133 GB is due to 4 nodes x 1 device x 100 = 400 / 3.0 = 133 . I belive the total storage available is 133 GB.

The Warning is good but should be all on one line or at least not have blank lines inserted in the middle of the statement.

# Cluster 1
# Total Storage allocated (GB) = 278
# Total Storage available (GB) = 200
Warning one or more persistent volumes are 

larger than the raw storage device size

[netzzer]

Please leave a blank line before and after Cluster1 and Cluster2 reporting. Also get rid of the '*' for some of the scenarios (e.g., choice 3, 4 two cluster).

@netzzer The 133 GB is due to 4 nodes x 1 device x 100 = 400 / 3.0 (replica 3) = 133 . I believe the total storage available is 133 GB.

^^ This is in reference to comment 2.

[netzzer]

Yes, Ramky, You are right about the 4 node condition that if storage device = 100GB then available storage for 4 nodes = 100GBx4 / 3 = 133 GB. My bad.

[netzzer]

Thinking we should add another warning if storage is oversubscribed in addition to having a PV size larger than the storage device. Something like this. User would have to start over similar to Warning for PV size being too large compared to storage device size.

Issue with choice#5. Need blank line between 'glusterfs' and '[OSEv3:children]'.

Also, for consistency I think adding info about available and allocated storage would be good for choice 5 (I know we decided to now do this but sort of strange without it). Especially for more than 3 nodes is not as intuitive about available storage.

This is not correct. There should be no Warning for the size of the PV verses the size of the storage device. The 2nd cluster is used for the registry + metrics PV and the storage size = 200 GB. Therefore, 150 GB size for registry PV is NOT larger than 200 GB.

Going to go ahead and merge. Any new fixes should go in new PR.

This is working better but need to add blank line now between cluster info and the inventory file options [OSEv3:children].
