XFS makes use of lazy evaluation techniques for file allocation. When a file is written to the buffer cache, rather than allocating extents for the data, XFS simply reserves the appropriate number of file system blocks for the data held in memory. The actual block allocation occurs only when the data is finally flushed to disk.
As of October 2006, the manpage for xfs on Debian states that: FUTURE DIRECTIONS Significant further development of xfs is unlikely. One of the original motivations behind xfs was the single-threaded nature of the X server — a user’s X session could seem to "freeze up" while the X server took a moment to rasterize a font.
ONTAP, Data ONTAP, Clustered Data ONTAP (cDOT), or Data ONTAP 7-Mode is NetApp's proprietary operating system used in storage disk arrays such as NetApp FAS and AFF, ONTAP Select, and Cloud Volumes ONTAP. With the release of version 9.0, NetApp decided to simplify the Data ONTAP name and removed the word "Data" from it, removed the 7-Mode image ...
A mount point is a location in the partition used as a root filesystem. Many different types of storage exist, including magnetic, magneto-optical, optical, and semiconductor (solid-state) drives. Many different types of storage exist, including magnetic, magneto-optical, optical, and semiconductor (solid-state) drives.
A file system with a logical journal still recovers quickly after a crash, but may allow unjournaled file data and journaled metadata to fall out of sync with each other, causing data corruption. For example, appending to a file may involve three separate writes to: The file's inode, to note in the file's metadata that its size has increased.
J/XFS is an alternative API to CEN/XFS (which is Windows specific) and also to Xpeak (which is Operating System independent, based on XML messages). J/XFS is written in Java with the objective to provide a platform agnostic client-server architecture for financial applications, especially peripheral devices used in the financial industry such ...
A network file system is a file system that acts as a client for a remote file access protocol, providing access to files on a server. Programs using local interfaces can transparently create, manage and access hierarchical directories and files in remote network-connected computers.
[3] [4] These are commonly known as network file systems, even though they are not the only file systems that use the network to send data. [5] Distributed file systems can restrict access to the file system depending on access lists or capabilities on both the servers and the clients, depending on how the protocol is designed.
