Linux users run it alongside filesystems to undertake critical tasks like the allocation of disks, mirroring, striping, and resizing of logical volumes. Logical Volume Manager, known as LVM, is a volume management tool for the Linux kernel. ZFS organizes and presents its storage pool as a virtual device (vdev).ZFS creates zpools, pooled data from multiple physical disks that it manages as a unified storage pool.You can expand or reduce the amount of disk space in a logical volume.You can dynamically resize the ext3 and ext4 filesystems, making them ideal for LVM.A logical volume can contain an entire filesystem like ext3 or ext4.Both ZFS and LVM use Copy-on-Write (COW), a resource management technique where a copy of original data is held while the source data is modified or updated.You can then manage the volume groups as single, large volumes, or smaller logical volumes (LVs). LVM facilitates the aggregation of multiple separate hard drives or disk partitions into a single volume group (VG).Sun Microsystems originally developed the Zettabyte File System (ZFS) as part of the Solaris OS.Logical volume managers run alongside a filesystem to provide easy, flexible disk space management.OpenSolaris, illumos distributions, OpenIndiana, FreeBSD, Mac OS X Server, NetBSD, Linux Heinz Mauelshagen, Sistina Software, IBM, Oracle Journaling file system and volume managerĭisk space management for the Linux kernelġ65,536 physical extents (PE) per logical volume (LV)Ħ4 characters per logical volume, 126 characters in total (volume group name + logical volume name) LVM is not a filesystem but operates in a layer that is distinct from the filesystem to perform disk management. This is a major difference because ZFS organizes and manages your data comprehensively. ZFS is a filesystem and volume manager combined. LVM is one of Linux’s leading volume managers and is alongside a filesystem for dynamic resizing of the system disk space. In this article, we share the key differences between LVM and ZFS and which option is best for your volume management needs. LVM and ZFS are two of the leading options for volume management on Linux, but they have significant differences in scope and performance. Volume management is critical to the management of disk space and uses storage virtualization to partition and organize data so you can use it efficiently. The Linux ecosystem provides a variety of open-source filesystem software, making it easy to arrange a filesystem setup that keeps you in control of your data.
