20+ practice questions focused on Configure local storage — one of the most tested topics on the Red Hat Certified System Administrator EX200 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Configure local storage PracticeA system administrator needs to add a new 10GB disk to an existing volume group 'vgdata' to extend logical volumes. Which of the following is the correct sequence of commands?
Explanation: Option A is correct because the proper sequence to add a new disk to an existing volume group is: first create a physical volume with `pvcreate /dev/sdb`, then extend the volume group with `vgextend vgdata /dev/sdb`, and finally extend the logical volume with `lvextend`. This order ensures the disk is initialized as a PV before it can be added to the VG, and the VG must have the new PV before the LV can be extended.
An administrator has created a RAID 1 array using mdadm with two 1TB disks. After a disk failure, the array is in a degraded state. Which command should be used to replace the failed disk with a new one?
Explanation: Option B is correct because it uses the `--manage` subcommand to first mark the failed disk (`/dev/sdb`) as failed with `--fail`, then remove it with `--remove`, and finally add the replacement disk (`/dev/sdc`) with `--add`. This is the proper sequence in mdadm to replace a failed disk in a RAID 1 array while the array is degraded.
An administrator needs to ensure that a specific LVM logical volume is automatically mounted at boot with the 'noexec' option. Which configuration file and entry should be used?
Explanation: Option C is correct because /etc/fstab is the standard configuration file for defining filesystem mount points and options that are applied automatically at boot. The entry specifies the logical volume device, mount point, filesystem type, and mount options including 'noexec' to prevent execution of binaries on that filesystem. The 'defaults' keyword ensures standard mount behavior is applied before the 'noexec' option overrides the exec permission.
After creating a new partition on /dev/sdc, the administrator runs 'partprobe' to inform the kernel of the change. What is the primary purpose of partprobe?
Explanation: The `partprobe` command is used to inform the operating system kernel of changes to the partition table without requiring a system reboot. After creating a new partition on `/dev/sdc`, running `partprobe` makes the kernel re-read the partition table from the disk, ensuring the new partition is recognized and accessible. This is essential for the kernel to update its in-memory representation of the disk's partitions.
An administrator wants to extend an XFS filesystem that resides on an LVM logical volume. The volume group has free physical extents. Which is the correct sequence?
Explanation: To extend an XFS filesystem on an LVM logical volume, you must first extend the logical volume with `lvextend` to allocate additional physical extents from the volume group, then grow the XFS filesystem to use the new space with `xfs_growfs`. XFS does not support online shrinking and requires the filesystem to be mounted for `xfs_growfs` to work. This sequence ensures the block device has sufficient capacity before the filesystem is expanded.
