Linux The Oracle Cluster File System ( OCFS , in its second version OCFS2 ) is a shared disk file system developed by Oracle Corporation and released under the GNU General Public License . The first version of OCFS was developed with the main focus to accommodate Oracle's database management system that used cluster computing .
In computing, specifically in Unix and Unix-like operating systems, a raw device is a special kind of logical device associated with a character device file that allows a storage device such as a hard disk drive to be accessed directly, bypassing the operating system's caches and buffers (although the hardware caches might still be used).
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 ...
It was created by Chris Mason in 2007 [15] for use in Linux, and since November 2013, the file system's on-disk format has been declared stable in the Linux kernel. [ 16 ] Btrfs is intended to address the lack of pooling, snapshots , integrity checking , data scrubbing , and integral multi-device spanning in Linux file systems . [ 9 ]
Oracle NoSQL Database Driver [10] partitions the data in real time and evenly distributes it across the storage nodes. It is network topology and latency-aware, routing read and write operations to the most appropriate storage node in order to optimize load distribution and performance.
Linux Logical Volume Manager (LVM) v1. Most volume-manager implementations share the same basic design. They start with physical volumes (PVs), which can be either hard disks, hard disk partitions, or Logical Unit Numbers (LUNs) of an external storage device.
ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.
