Disks are partitions of an integrated storage data store that can be allocated to specific virtual servers. OnApp Storage disks are managed through the Control Panel > Storage menu.

You can view the list of  Integrated Storage data store disks and its details.


View List of Integrated Storage Data Store Disks



To view the list of Integrated Storage data store disks:

  1. Go to your Control Panel > Storage > Data Stores menu.
  2. Click the label of the required data store.
  3. Scroll down to the list of disks to view the list of all data store disks with the following details:

    • Identifier - disk's identifier
    • Label - disk's label
    • Size - disk's size
    • Utilization - disk utilization rate
    • Virtual machine - the virtual server that utilizes this disk
    • Data store - the data store to which this disk belongs
    • In sync? - whether the disk is synced or not
    • Snapshot? - disk's backup status



View Integrated Storage Data Store Disks Details



To view Integrated Storage data store disks details:

  1. Go to your Control Panel > Storage > Data Stores menu.
  2. Click the label of the required data store.
  3. Scroll down to the list of disks and click the label of the disk you are interested in.
  4. You will get  the following disk details:

    • Virtual Server - label of VS, which utilizes this disk. You can click the VS label to be redirected to the VS
    • Size - disk's size
    • Utilization - disk utilization rate
    • Copies - the number of disk's replicas
    • Stripes -the number of disk's stripes
    • Performance - performance benchmark status
    • Consistency - disk consistency status

Also there are the following buttons:

  • Discard Cache - click this button to discard all caches for the disk
  • Refresh Resync Status - click this button to refresh disk resync status
  • Show IO Statistics - clicking this button will redirect you to IO statistics chart
  • Delete Disk - click this button to delete disk


  • Allocated space is the space that is allocated to vDisks. This space is equal to the size of all vDisk stripes on a back-end node.
  • Utilized space is the space that is used when data is written to a vDisk. The space the data consumes is reflected in the back-end node utilization.

Below you can see storage nodes and Rebalance Disk button, which allows to move the data from one node to another.



VDisk Status Codes (insyncstatus)


Each VDisk gives a status code which reflects its current status. This can be pulled using the onappstore command on any compute resource or backup server that is integrated storage enabled and part of the relevant compute resource zone: 

onappstore diskinfo uuid=<UUID> filter=insyncstatus
CODE

# vdisk sync statuses
OUT_OF_SYNC = 0
IN_SYNC = 1
MISSING_ACTIVE_MEMBERS = 2
MISSING_INACTIVE_MEMBERS = 3
MISSING_PARTIAL_MEMBERS = 4
MISSING_UNKNOWN_MEMBERS = 5
PARTIAL_MEMBERSHIP_GOOD_CONTENT = 6
PARTIAL_MEMBERSHIP_BAD_CONTENT = 7
MEMBERSHIP_GEN_COUNT_MISMATCH = 8
