An administrator wants to check the health and status of the RAID arrays on a Linux system. Which file should be examined to find the most comprehensive information about the RAID devices?
The correct answer is '/proc/mdstat' because this virtual file provides detailed information about the status of RAID arrays. It includes the status of each RAID device, details about individual disks, and the progress of any ongoing RAID recovery or resynchronization. Other options mentioned do not serve the purpose of RAID monitoring. '/etc/mdadm.conf' is used for RAID configuration, not status monitoring. '/dev/md0' is a device file for a specific RAID array, not a status file. '/proc/partitions' provides partition information, but not detailed RAID array status.
