How Do I Do If the Disk Status Displayed in the System.disks Table Is fault or abnormal?

Symptom

How do I do if the disk status displayed in the System.disks table is fault or abnormal?

Procedure

This problem is caused by I/O errors on the disk. To rectify the fault, perform the following steps:

  • Method 1: Log in to FusionInsight Manager and check whether an alarm is generated indicating that the disk I/O is abnormal. If yes, replace the faulty disk by referring to the alarm help.
  • Method 2: Log in to FusionInsight Manager and restart the ClickHouse instance to restore the disk status.

    If an I/O error occurs but the disk is not replaced, the disk status will still turn to fault or abnormal.
