Edit a Volume

After creating a volume, you can edit your volume by clicking the ⋮ button and selecting the Edit Config option.

Expand a Volume

You can expand a volume by increasing the value of the Size parameter directly. To prevent the expansion from interference by unexpected data R/W, Harvester supports offline expansion only. You must shut down the VM or detach the volume first if it is attached to a VM, and the detached volume will automatically attach to a random node with maintenance mode to expand automatically.

Cancel a Failed Volume Expansion

If you specify a size larger than Longhorn’s capacity during the expansion, the status of the volume expansion will be stuck in Resizing. You can cancel the failed volume expansion by clicking the ⋮ button and selecting the Cancel Expand option.
