Disk Replacement

{{ $t('productDocDetail.updateTime') }}: 2026-01-05

Description

When a node in the cluster has a disk failure, it needs to be replaced with a new disk. (Supports data disk, cache disk replacement).

Precautions

  1. After the disk is replaced, data rebuilding will be triggered, affecting the business. It is recommended to operate when the business is idle.
  2. If the RAID of the aServer is in JBOD mode, the disk supports hot swapping, and it is possible to unplug the faulty disk and insert a new disk without shutting down the server.
  3. If the RAID card of the aServer device is in RAID 0 mode, the disk does not support hot-swapping, and the server needs to be powered off and then replaced. Set the single disk to RAID 0 for the new disk and perform the front-end operation.
  4. After the disk of the aServer machine fails, you must purchase a Sangfor disk before replacing the disk. Non-Sangfor disk virtual storage cannot be recognized.
  5. The location of the new disk must be on the same node as the failed disk. It is recommended to use the original disk.
  6. For aCloud 5.8.6 and earlier versions, you need to contact Sangfor technical assistance to refresh the cached data before running the cache disk.

Prerequisites

  1. The capacity of the new disk should be the same as the size of the failed disk (it is strictly forbidden to replace the disk with a capacity smaller than the capacity of the failed disk).
  2. Ensure that no tasks are running on the Task Execution page of the virtual storage.

Steps

  1. Find the faulty disk in Storage > Virtual Storage > Physical Disks, select the faulty disk, and click Replace Disk.
  2. Unplug the failed disk first, insert the new disk, and check the I'm ready checkbox.
  3. Select the new disk and click Next.
  4. Confirm the information about the new disk and the faulty disk, check the I'm sure I want to replace the disk checkbox, and click Finish, and then the platform starts to replace the disk.
  5. After the replacement is complete, you can see no offline disks on the physical disk interface.
  6. After the replacement is completed, perform Health Check to confirm that the platform is running stably.
