lxc is a command-line tool in Linux used to manage Linux containers. The tool communicates with a container manager service, such as lxd, using the lxd REST API. Containers are isolated environments that allow you to run applications and services in a contained, isolated environment within a host operating system. The lxc command provides a […]

lvs is a command in Linux used to display information about Logical Volumes (LVs) in a Linux Logical Volume Manager (LVM) system. The lvs command outputs a table of information about each LV in a system, including LV name, volume group (VG) name, size, status, and more. The lvs command can also be used with […]

lvresize is a command in Linux used to resize a Logical Volume (LV) in a Linux Logical Volume Manager (LVM) system. The command can be used to increase or decrease the size of a LV. When increasing the size of a LV, the lvresize command can also be used to resize the filesystem that is […]

The lvm command is used to manage physical volumes, volume groups, and logical volumes in a Linux Logical Volume Manager (LVM) system. The lvm command launches an interactive shell, allowing you to perform various LVM management operations. Physical volumes (PVs) represent the actual storage devices, such as hard drives or solid-state drives, in a LVM […]

Logical Volume Manager 2 (LVM2) allows you to aggregate physical storage devices into volume groups. You can then divide that aggregated space into one or more logical volumes. Once created, logical volumes can be extended to utilize unused space within the volume group, allowing the file system residing on the logical volume to be extended […]

lvdisplay is a command in Linux used to display information about Logical Volumes (LVs) in a Linux Logical Volume Manager (LVM) system. The output of the command shows details such as LV name, VG name, size, read/write status, access permissions, and more. The command is used to view the properties of LVs and to verify […]

lvcreate is a Linux command used to create a logical volume (LV) in a Linux Logical Volume Manager (LVM) setup. A logical volume is a virtual block device that provides a layer of abstraction between the physical storage and the file system. This allows for more flexible and dynamic management of storage, such as resizing […]

The ltrace command can be used to intercept and record the dynamic calls made to shared libraries. The amount of output generated by the ltrace command can be overwhelming for some commands (especially if the -S option is used to also show system calls). You can focus the output to just the interaction between the […]
