To prepare for this exam, your are highly encouraged to use the LFCE series as well. LFCS: Manage LVM and Create LVM Partition – Part 11 One of the most important decisions while installing a Linux system is the amount of storage space to be allocated for system files, home directories, and others. If you make a mistake at that point, growing a partition that has run out of space can be burdensome and somewhat risky. Logical Volumes Management (also known as LVM), which have become a default for the installation of most (if not all) Linux distributions, have numerous advantages over traditional partitioning management. Perhaps the most distinguishing feature of LVM is that it allows logical divisions to be resized (reduced or increased) at will without much hassle. The structure of the LVM consists of: One or more entire hard disks or … [Read more...] about LFCS: How to Manage and Create LVM Using vgcreate, lvcreate and lvextend Commands

A ZFS developer’s analysis of the good and bad in Apple’s new APFS file system
Data Integrity Arguably the most important job of a file system is preserving data integrity. Here's my data, don't lose it, don't change it. If file systems could be trusted absolutely then the "only" reason for backup would be the idiot operators (i.e. you and me). There are a few mechanisms that file systems employ to keep data safe. Redundancy APFS makes no claims with regard to data redundancy. As Apple's Eric Tamura noted at WWDC, most Apple devices have a single storage device (i.e. one logical SSD) making RAID, for example, moot. Instead, redundancy comes from lower layers such as Apple RAID (apparently a thing), hardware RAID controllers, SANs, or even the "single" storage devices themselves. As an aside, note that SSDs in most Apple products where APFS will run include multiple more-or-less independent NAND chips. High-end SSDs do implement data redundancy within the device, but it comes at the price of reduced capacity and performance.
