Symptoms

ECS disk partially allocated disk
ECS disk has no block bins
ECS disk is 1% full
ECS disk is not 100% full
ECS disk is not preallocated

To confirm if you have this issue:

Command:
# svc_disk list -capacity -a
Example: (truncated output disks in unknown are the replaced or disks expanded to) 
ecs03:~ # svc_disk list -capacity -a

Further confirm that the new drives are counted in cs_hal, fabric, and the object-main container. (in this example 15 is detected after adding 5 on each node)
Command:
viprexec -i "docker exec object-main df | grep -c uuid-"
Example:

### Checking the object-main container for mounted disk count
admin@ecs:~> viprexec -i "docker exec object-main df | grep -c uuid-"

Output from host : 192.168.219.1

Command:
viprexec -i "/opt/emc/caspian/fabric/cli/bin/fcli agent disk.disks | grep -cw MOUNTED"
Example:

When querying SSM for one of the nodes you can see the new disks UUIDs are missing.(Should be missing the ones "unknown" in svc_disk command above)
Command:
ssh 169.254.<rack number>.<node number> "/opt/emc/caspian/fabric/cli/bin/fcli agent node.id" | grep id
Example:

### Get device ID of impacted node
admin@ecs:~> ssh 192.168.219.6 "/opt/emc/caspian/fabric/cli/bin/fcli agent node.id" | grep id
  "id" : "515190ac-35a0-4557-80af-8bc9790449b4",
Command:
svc_dt search SS/1/SSTABLE_KEY -t PARTITION -k device=<id from above> | grep schema
Example:

### Query SSM of node6
admin@ecs:~> svc_dt search SS/1/SSTABLE_KEY -t PARTITION -k device=515190ac-35a0-4557-80af-8bc9790449b4 | grep schema

Cause

Minor code issue. Once it is confirmed SSM has a different count than object-main mounted disks, fabric-mounted disks, and cs_hal total count go to the resolution section.
