Linux kernel 5.10, released in December 2020, included the new on-disk format XFS v5. This was a hard break, since the deprecated XFS v4 can not be converted to XFS v5. Data on partitions formatted with XFS v4 has to be backed up to another partition or media in order to restore it after formatting the old partition with XFS v5, which ...
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.

Shared-disk file systems normally do not scale over 64 or 128 nodes. Shared-disk file systems may be symmetric where metadata is distributed among the nodes or asymmetric with centralized metadata servers. CXFS (Clustered XFS) from Silicon Graphics (SGI). Available for Linux, Mac, Windows, Solaris, AIX and IRIX. Asymmetric.
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...

In addition, since a NAND-based storage device shows different characteristics according to its internal geometry or flash memory management scheme (such as the Flash Translation Layer or FTL), it supports various parameters not only for configuring on-disk layout, but also for selecting allocation and cleaning algorithms.
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 ...
