How do mount, umount, and /etc/fstab manage storage filesystems?
❓ Interview Prompt: Explain mounting storage devices, mount command, umount, UUID identification, and persistent /etc/fstab configuration.
Connecting storage device partitions to the Linux directory tree requires mounting:
Operations:
•
'mount /dev/sdb1 /mnt/data': Attaches filesystem partition to mount point directory.
•
'umount /mnt/data': Detaches filesystem safely.
•
'/etc/fstab': Configuration file defining persistent filesystems mounted automatically at system boot using device UUIDs.
Code Implementation Example
bash
# View all currently mounted filesystems
mount | column -t
# Sample /etc/fstab persistent mount entry using UUID:
# UUID=a1b2c3d4-e5f6 /var/data ext4 defaults,noatime 0 2💡Inspecting active mounts and configuring persistent storage in /etc/fstab.
🎯 Interview Key Takeaway
Use device UUIDs in /etc/fstab for reliable persistent filesystem mounting across reboots.
