Handling Read-Only Disk

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

Description

If the hard disk is mounted as read-only due to an abnormality in the hard disk, the write operation on the hard disk will be blocked. Sangfor Virtual Storage will identify the read-only hard disk and isolate it. If it occurs three times within 24 hours, the hard disk is isolated to avoid affecting the customer's business.

Precautions

  1. Two node environments do not support isolating read-only hard disks.
  2. PCIe disks currently do not support handling read-only disks.
  3. The witness node currently does not support handling read-only disks.
  4. If the virtual datastore has not been created, handling read-only disks are not supported.
  5. Hybrid volumes only support handling read-only disks of data disks, not cache disks.
  6. Data disks in all-flash volumes support handling read-only disks.
  7. If a disk is newly created/expanded/replaced, handling read-only disks will take effect 30 minutes after the disk is online.

Prerequisites

None.

Steps

Log in to the HCI platform and view the hard disk status on the Storage >Virtual Storage > Physical Disks interface. When a read-only disk fails, the platform automatically isolates the hard disk and generates an alert on the interface.
