In Linux systems, you can use the mdadm command to view RAID information.<\/p>\n

    \n
  1. Firstly, make sure that the mdadm tool is installed in the system. If it is not installed, you can use the following command to install it:<\/li>\n
  2. Install mdadm using the command sudo apt-get.<\/li>\n
  3. Use the following command to view information about RAID devices in the current system:<\/li>\n
  4. Execute the command “sudo mdadm –detail –scan”<\/li>\n
  5. This command will display information about the configured RAID devices, including device name, RAID level, number of devices, and status.<\/li>\n
  6. You can use the following command to view detailed information about the specified RAID device:<\/li>\n
  7. Display detailed information about the RAID array named \/dev\/mdX.<\/li>\n
  8. Replace \/dev\/mdX with the actual RAID device name, such as \/dev\/md0.<\/li>\n
  9. To check the real-time status of RAID devices, you can use the following command:<\/li>\n
  10. Monitor the RAID status by running the command “watch -n 1 cat \/proc\/mdstat”<\/li>\n
  11. This command refreshes the status information of the current RAID device every 1 second.<\/li>\n<\/ol>\n

    Note: the “sudo” in the above command is used to obtain administrator privileges.<\/p>\n","protected":false},"excerpt":{"rendered":"
