A server has a RAID 1 array containing the root filesystem. The administrator needs to replace one of the disks in the array with a larger disk. After replacing the disk and adding it to the array, the rebuild completes. The administrator wants to use the extra space on the new disk. What additional steps are required?

Add the new disk to /etc/fstab with the new size

Resize the filesystem with resize2fs and then grow the array

Grow the array with mdadm --grow --size=max and then resize the filesystem

Recreate the array with the new disk and restore the data

What is the purpose of including the mdadm configuration file (e.g., /etc/mdadm/mdadm.conf) in the initramfs?

It allows the kernel to assemble the RAID array automatically during the boot process.

It stores the encryption keys for the RAID array.

It provides a backup of the RAID metadata.

It speeds up the RAID rebuild process.

An administrator manages a server with a RAID 6 array. The administrator wants to proactively verify that the parity data is consistent and correct any discrepancies. Which command should the administrator run?

echo check > /sys/block/md0/md/sync_action
