In this lesson
Prepare for the Linux+ XK0-006 exam (CompTIA Linux+ V8). In this lesson: MBR and GPT partitions (fdisk, gdisk, parted), filesystems (ext4, XFS, Btrfs, tmpfs), LVM physical volumes, volume groups, and logical volumes (create, extend, resize, move), and RAID levels with mdadm, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.
Preview the topics
- Pinecrest grew the virtual disk of a cloud server from 50 to 100 GB, but lsblk shows the root partition is still 50 GB. Which command extends the partition into the new space?
- The media volume group is full. A new disk was just added, and the media logical volume holds an XFS filesystem that must grow without downtime. What is the right order?
- The new storage server has four disks for the master copies, and the array must keep working if any two disks fail at the same time. Which RAID level fits?
