On small systems (like a desktop), instead of having to estimate at installation time how big a partition might need to be, LVM allows filesystems to be easily resized as needed. Performing consistent backups by taking snapshots of the logical volumes. Encrypting multiple physical partitions with one password.
Systems can use LVs as raw block devices just like disk partitions: creating mountable file systems on them, or using them as swap storage. Striped LVs allocate each successive LE from a different PV; depending on the size of the LE, this can improve performance on large sequential reads by bringing to bear the combined read-throughput of ...
Linux, FreeBSD and NetBSD [citation needed] OverlayFS is a union mount filesystem implementation for Linux. It combines multiple different underlying mount points into one, resulting in single directory structure that contains underlying files and sub-directories from all sources.
The file system being cloned should not be mounted. GParted clones partitions at the filesystem-level, and as a result is capable of cloning different target-size partitions for the same source, as long as the size of the source filesystem does not exceed the size of the target partition. [12]
Quick crash recovery on-mount; Read-ahead for meta data files as well as data files; Block sizes smaller than page size (e.g. 1KB or 2KB) Online resizing (since Linux-3.x and nilfs-utils 2.1) Related utilities (by contribution of Jiro SEKIBA) grub2; util-linux (blkid, libblkid, uuid mount) udisks, palimpsest; File system label (nilfs-tune)
XFS is a 64-bit file system [24] and supports a maximum file system size of 8 exbibytes minus one byte (2 63 − 1 bytes), but limitations imposed by the host operating system can decrease this limit. 32-bit Linux systems limit the size of both the file and file system to 16 tebibytes.
Unlike the concept of UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces. Drive letter assignment is thus a process of using letters to name the roots of the "forest" representing the file system; each volume holds an independent ...
aufs (short for advanced multi-layered unification filesystem) implements a union mount for Linux file systems. The name originally stood for AnotherUnionFS until version 2. Developed by Junjiro Okajima in 2006, [ 1 ] aufs is a complete rewrite of the earlier UnionFS .
