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.
Stratis is not a user-level filesystem like the Filesystem in Userspace (FUSE) system. Stratis configuration daemon was originally developed by Red Hat to have feature parity with ZFS and Btrfs . The hope was due to Stratis configuration daemon being in userland, it would more quickly reach maturity versus the years of kernel level development ...
Shared-disk file systems (also called shared-storage file systems, SAN file system, Clustered file system or even cluster file systems) are primarily used in a storage area network where all nodes directly access the block storage where the file system is located. This makes it possible for nodes to fail without affecting access to the file ...
To replace the MINIX file system, the extended file system (or ext) was developed. However, ext retained some problems such as poor performance and the lack of some date stamps. Two contenders for replacing ext were quickly developed: ext2 and Xiafs. The two file systems were included in the standard kernel in December 1993 (Linux 0.99.15).
To implement a new file system, a handler program linked to the supplied libfuse library needs to be written. The main purpose of this program is to specify how the file system is to respond to read/write/stat requests. The program is also used to mount the new file system. At the time the file system is mounted, the handler is registered with ...
The client itself is a lightweight kernel module that does not require any kernel patches. The servers run on top of an existing local file system. There are no restrictions to the type of underlying file system as long as it supports POSIX; recommendations are to use ext4 for the metadata servers and XFS for the storage servers. Both servers ...
The Cluster File System provides cache coherency and POSIX compliance across nodes, so that data changes are atomically seen by all cluster nodes simultaneously. Because Cluster File System shares the same binaries and same on-disk layout as single instance VxFS, moving between cluster and single instance mode is straightforward.
Unionfs is a filesystem service for Linux, FreeBSD and NetBSD which implements a union mount for other file systems.It allows files and directories of separate file systems, known as branches, to be transparently overlaid, forming a single coherent file system.
