Let's see how much you know about Linux: Managing Storage
Which command displays information about all block storage devices that are currently available on the system?
Each file that is opened in Linux is assigned a file descriptor that keeps track of the file when it is open. It is possible, on a very busy server where a great many files may be opened simultaneously, that the descriptors could all be consumed. What common storage issue does this describe?
As defined in the Filesystem Hierarchy Standard (FHS), the topmost directory in a Linux file system is the root directory, indicated by a single forward slash (/). Below the root directory are various subdirectories that are standardized as part of the FHS. Which subdirectory stores hardware and software device drivers and maintains file system entries that represent the devices connected to the system?
Which procedure for managing file systems has a step to enter dumpe2fs {file system name} to display file system information for ext file systems?
Which one of the storage devices that are supported by the Linux operating system uses electromechanical devices that use magnetic storage technology to store data, usually in large amounts?
What is an object that stores metadata about a file or directory on a file system?
What process describes the abstraction of physical storage devices into virtual storage devices?
What mount option specifies that only the root user can mount a device or a file system?
Which one of the tune2fs command options specify the maximum time interval between file system checks in days, months, or weeks?
You need a file system that does not provide the same capabilities as more modern file systems and is typically used for compatibility reasons. Which file system supported by Linux is compatible with many different operating systems, including all versions of Unix, Windows, and macOS?
You're a new system administrator and your manager comes to your cubicle to give you a pop quiz over a few concepts. The first one she asks you is to show her how you would set up a new partition on the second storage drive on a Linux system. Which command can you enter to perform this operation?
A junior administrator asks for your help with setting up a new Linux file system, /dev/sdb2. He retraces his steps with fdisk, creating the partition and saving the setup. But now, he can't figure out why he can't use the file system—how can you help him? After inspecting his work in fdisk, you tell him that he must build the file system with the mkfs command. You assist him by entering the following command:
You created a new partition, /dev/sdb1, created the file system (XFS), and mounted the file system as /Files. You also created a few directories on / Files for various groups within your organization as shared file spaces. After a maintenance reboot a few days later, users are complaining that their directories and files that you set up no longer exist. What is the problem?
One of the developers has told your manager that he needs the file system / code rebuilt using the XFS file system type. Which utility can you use?
You and the other system administrators have a maintenance partition, /maint, that you only want mounted when required for administrative activities. How can you use the file system only when you need it?
You need to create a new volume for Human Resources. That group has purchased a new 1 TB drive for their volume. What is the first step in the process of creating the logical volume?
How can you create a physical volume on /dev/sdd1?
Which command can you use to create a new volume group, shared, with /dev/sdb1 and /dev/sdd1? And then how do you view your volume groups?
Which command can you use to create a new 400 GB logical volume, finance, from volume group vg_finance?
How can you remove the physical volume /dev/sde1?
What are the three requirements for mounting a file system?
choose three answers from the list below
Hint
What final task do you need to complete in mounting a new file system to have that new file system mount at boot time?
What is the generic format of the /etc/fstab file?
How can you unmount the /finance file system?
If you issue the following command: sudo umount /share1 and you receive the error that the resource is busy, how do you fix the problem and unmount the file system?
