The application team is having issues accessing their data in their /app file system. Give the following outputs: Which of the following is the reason for this issue?

While incorrect mounting could prevent access, a missing physical volume is a more fundamental storage layer issue that would prevent successful mounting in the first place or cause the mount to fail.

An incorrect `/etc/fstab` configuration would typically prevent the filesystem from mounting at boot, but it doesn't address the underlying physical storage problem.

In Linux Logical Volume Management (LVM), filesystems often reside on logical volumes that are built upon volume groups, which in turn are composed of physical volumes. If a physical volume is missing or inaccessible, the entire LVM structure it contributes to can become unavailable, preventing the corresponding logical volume and its filesystem from being mounted or accessed.

Data deletion implies the filesystem itself is accessible but empty, which contradicts the problem of 'issues accessing their data in their /app file system,' suggesting the filesystem isn't available.
