Replacing storage pool sets

How to replace storage pool sets.

Before you begin

Before you replace Storage Pool sets, you must perform the following preconditions:
  1. Upgrade all Accesser® Nodes and Slicestor® Nodes to ClevOS 3.10.0 or newer.
  2. Approve an amount of Slicestor® Nodes equal to a multiple of the least common multiple of all the vault IDA widths for the vaults that use the Storage Pool that you want to replace. If you are using Concentrated Dispersal, you can replace sets by using either the Concentrated Dispersal set size or an integer multiple of the full IDA Width.

To replace one or more Storage Pool sets:

Procedure

  1. In the Configure tab, click the Storage Pool you want to replace.
  2. In the Slicestor Devices section, click Change Sets and Devices.
  3. Click Configure Set Replacement.
  4. In the Sets to Replace section, select the Storage Pool sets you want to replace.
  5. Select the Slicestor® Nodes you want to use to replace the Storage Pool sets.
    The devices are used to form a new Device Set within this Storage Pool.
  6. Select the Slicestor® Nodes you want to add for the new Device Set in one of the following ways:
    • Select the check boxes for choosing Slicestor models with similar drive counts
    • Check the check boxes for one or more Sites to add nodes by Site.
    • Check the check boxes in the Devices section to add individual nodes.
    • Click Suggest Devices to allow the Manager application to select Slicestor® Nodes on your behalf.
  7. Click Save. The new set is now part of the storage pool "pending addition" and the replaced sets are "pending removal."
  8. If additional set replacements are to be added, repeat steps 3-7. If other set changes are to be configured, perform those. Otherwise, from the Slicestor Devices section click Start Reallocation. A confirmation page appears.
  9. If the proposed set changes are correct, click Start Reallocation to begin data reallocation.
  10. Monitor the progress of the reallocation and ensure it continues to completion.
  11. Change the Storage Pool Reallocation Rate.
