Pool Management

This topic applies to the page in XInsight for managed systems running KSM 1.1 or later.

The Pool page provides options for creating and managing storage pools, disk groups, and volumes on a KSM system.

Go to Storage > Pool. Select a pool from the Pools panel to view its capacity, health, disk groups, volumes, and available management options.

Create a Pool #

Click the + icon in the lower-left corner of the Pools panel to open the New Pool Creation wizard.

The wizard includes the following stages:

  1. Create Pool
  2. Create Disk Group
  3. Create Volume
  4. Ready to Complete

Create Pool #

KSM systems support Thick Provisioning pools only.

Enter a unique Pool Name.

Enable Pool Encryption toggle when the pool uses supported self-encrypting drives (SEDs).

Note: When Pool Encryption is enabled, only eligible SEDs are available for selection.

Create Disk Group #

Select one or more disks from the Disk List. The selected disks appear under Selected Disks.

Under Disk Group Settings, configure the following settings:

  • RAID Level: Select the RAID level for the disk group. The available RAID levels depend on the number and type of selected disks.
  • High Latency Disk Warning: Enable this toggle to monitor for disks that may introduce unusually high I/O latency.
  • Capacity: Displays the usable capacity of the disk group based on the selected disks and RAID configuration.

When the disk group configuration is valid, click Next.

Note: Mixing SSDs and HDDs in the same disk group may reduce overall storage performance.

Create Volume #

Enter a Volume Name and specify the Capacity.

Ready to Complete #

Review the pool, disk group, and volume settings.

The summary displays the configured pool capacity and encryption status, disk group capacity and RAID level, and volume capacity.

Click Previous to modify the settings or Finish to create the pool.

Pool Information #

Select Pool to view the basic information for the selected pool, including the pool name, allocated and unallocated capacity, and current health status.

The usage bar indicates the percentage of the pool capacity that is currently allocated.

The Health field can display the following states:

  • Good: The pool is operating normally.
  • Degraded: One or more disk groups have encountered an issue, but the pool remains operational.
  • Failed: The pool is damaged and unavailable for normal use.

Disk Groups #

Select Disk Groups to view the disk groups assigned to the pool.

Expand a disk group to view the following information:

  • Capacity
  • RAID
  • High Latency Disk Warning
  • Disks

Click Disk Info to view information about the disks in the selected disk group, including the enclosure, slot, status, interface, type, speed, capacity, and block size.

Create a Disk Group #

Click the + icon in the lower-left corner of the Disk Groups panel to open the Create New Disk Group window.

Select the disks to include in the disk group. The selected disks appear under Selected Disks.

Configure the RAID Level and High Latency Disk Warning setting as required, and then click Finish.

Warning: Avoid using RAID 0 for data that requires redundancy. RAID 0 provides no fault tolerance.

Remove a Disk Group #

Select the disk group to remove, and then click the − icon in the lower-left corner of the Disk Groups panel.

Restriction: A disk group can be removed only if no data has been written to it. If the disk group contains data, the system does not allow it to be removed.

Volume #

Select Volume to view the volumes in the selected pool.

Each volume displays its current operating status and capacity. Expand a volume to view its details.

Volume Status #

The status displayed next to the volume name indicates its current operating state.

The Status field can display the following states:

  • Online: The volume is available for normal use.
  • Offline: The volume is not available for normal use.
  • Rebuilding, Migrating, Scrubbing, Cloning, Rolling back, Pre-checking, Replicating, Erasing, Moving, Relocating, EE-Rebuilding, or Initiating: Indicates that the corresponding volume operation is in progress.

Volume Health #

The Health field indicates the current health condition of the volume and can display the following states:

  • Optimal: The volume is operating normally.
  • Partial Optimal: The volume has encountered a read or write error but remains operational.
  • Degraded: One drive associated with the volume has failed, but the volume remains accessible.
  • Failed: The volume is no longer available for normal use.

Create a Volume #

Click the + icon in the lower-left corner of the Volumes panel to create an additional volume.

Enter a Volume Name, specify the Capacity, and configure the available volume settings as required.

Click Finish to create the volume.

Remove a Volume #

Click the − icon in the lower-left corner of the Volumes panel, select the volume to remove, and then confirm the deletion.

Warning: Deleting a volume permanently removes the volume and all data stored on it. This action cannot be undone. Back up all required data before deleting the volume.

Delete a Pool #

Under Pool Deletion, click Delete.

Review the confirmation message, and then confirm the deletion.

Warning: Deleting a pool permanently removes the pool, its volumes, and all stored data. This action cannot be undone. Back up all required data before deleting the pool.

Attention: If the pool contains system volumes, deleting the pool may affect system functionality.
