Storage resizing

IMPORTANT: Before beginning a storage resize operation, ensure all backup, replication, and cleaner operations are stopped.

The QoreStor VM supports the ability to incorporate additional storage capacity. Adding storage capacity has the following requirements:

  • Storage must be added through the virtualization platform before performing any operations on the QoreStor VM.
  • Newly added storage must be discovered by QoreStor.
  • If your QoreStor license does not currently allow for the newly added storage, the QoreStor licensing must be updated to reflect the additional capacity.

To add storage to QoreStor:

  1. Refer to the documentation for your virtualization platform version for instructions on resizing hard disks.
  2. For Tier 1 VMs, locate the data disk and expand it to the desired size. Refer to QoreStor VM Specifications for maximum supported storage size.


    For Tier 2 VMs, locate each of the three data disks and expand each disk equally. Refer to QoreStor VM Specifications for maximum supported storage size.

    IMPORTANT: When the QoreStor VM discovers the newly added free space, the discovered amount will be equal to the smallest available amount. For proper operation, each data disk must be expanded to the same size.

  3. After resizing the data disks, poweron the QoreStor VM and access the QoreStor Administration menu.
  4. Select Storage resize. The newly added space will be detected. Select OK to allocate the storage.

    NOTE: QoreStor services will be restarted.

  5. You will be prompted when the system has fully restarted. Select Done.
  6. If youre newly configured storage space exceeds your licensed capacity, add a new QoreStor license. Refer to the QoreStor User Guide for more information.
