mdadm: Show RAID info.

mdadm

$ sudo mdadm --detail ${-dev-md0}

try on your machine

The command "sudo mdadm --detail ${-dev-md0}" is used to show detailed information about a software RAID device, specifically the RAID array identified as "md0".

Let's break down the command:

"sudo": The "sudo" command is used to execute the subsequent command with administrative privileges. It allows the user to perform actions as a superuser or another specified user.
"mdadm": This command is used to manage and monitor software RAID arrays in Linux. It stands for "Multiple Device Administrator".
"--detail": This is an option or parameter provided to the "mdadm" command to specify that detailed information about the RAID array should be displayed.
"${-dev-md0}": This is a variable that represents the path to the RAID device or array. In this particular command, "${-dev-md0}" is likely a placeholder and should be replaced with the actual path to the RAID device or array. For example, if the RAID array is located at "/dev/md0", the command would be "sudo mdadm --detail /dev/md0".

By running this command with the correct RAID device path, you will receive a detailed report about the specified RAID array, including information about its devices, RAID level, size, status, etc.
