A storage engineer is troubleshooting a server that uses device mapper for a RAID1 logical volume. The server was recently rebooted, and the logical volume is not appearing in /dev/mapper/. The engineer suspects that the device mapper table was not recreated. Which command should the engineer use to recreate the device mapper mapping for the RAID1 device?

dmsetup create raid1 --table '0 20971520 raid1 2 8:16 8:32'

An administrator needs to enforce a disk quota for a user on a filesystem mounted at /home. The quota should limit the user to 2 GB of space and 5000 inodes. The administrator has already installed the quota tools. Which steps are required to enable quotas on the filesystem?

Create the quota files manually and then set the limits with setquota.

Run quotacheck and then use edquota to set the limits.

Add 'usrquota' to the mount options in /etc/fstab, remount the filesystem, and run quotacheck.

Use the 'quotaon' command to enable quotas and then set limits with edquota.
