The on-disk layout of VxFS is versioned and upgradeable while the file system is mounted. This file system has gone through ten versions. Version 2 added support for filesets, dynamic inode allocation and ACLs. Layouts 1-3 stopped being supported in VxFS 4.0. Version 4 added support for storage checkpoints and for Veritas Cluster File System ...
XFS excels in the execution of parallel input/output (I/O) operations due to its design, which is based on allocation groups (a type of subdivision of the physical volumes in which XFS is used- also shortened to AGs). Because of this, XFS enables extreme scalability of I/O threads, file system bandwidth, and size of files and of the file system ...
Dynamically optimized disk-layout through allocate-on-flush (also called delayed allocation in XFS) Delayed actions (tree balancing, compression, block allocation, local defragmentation) R and D (Rare and Dense) caches, synchronized at commit time; Transactions support for user-defined integrity; Metadata and inline-data checksums [7] Mirrors ...
The layout of a disk with the GUID Partition Table. In this example, each logical block is 512 bytes in size and each entry has 128 bytes. The corresponding partition entries are assumed to be located in LBA 2–33. Negative LBA addresses indicate a position from the end of the volume, with −1 being the last addressable block.
The Write Anywhere File Layout (WAFL) is a proprietary file system that supports large, high-performance RAID arrays, quick restarts without lengthy consistency checks in the event of a crash or power failure, and growing the filesystems size quickly.

To bring a volume group online, the "vgchange" tool: Searches for PVs in all available block devices. Parses the metadata header in each PV found. Computes the layouts of all visible volume groups. Loops over each logical volume in the volume group to be brought online and: Checks if the logical volume to be brought online has all its PVs visible.
