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.
In computing, the Global File System 2 (GFS2) is a shared-disk file system for Linux computer clusters. GFS2 allows all members of a cluster to have direct concurrent access to the same shared block storage, in contrast to distributed file systems which distribute data throughout the cluster.
ReiserFS is a general-purpose, journaling file system initially designed and implemented by a team at Namesys led by Hans Reiser and licensed under GPLv2.Introduced in version 2.4.1 of the Linux kernel, it was the first journaling file system to be included in the standard kernel.
Xiafs was less powerful and offered less functionality than ext2. The maximum size of a file was 64 MiB and the maximum size of a partition was 2 GiB. While this was an improvement over ext, it did not measure up to ext2. Xiafs used less disk space for its control structures and it had greater stability at that time.
This allows the user to change any of the files on the system, with the new file stored in the image and transparently used instead of the one on the CD. [4] Unionfs can also be used to create a single common template for a number of file systems, or for security reasons. It is sometimes used as an ad hoc snapshotting system.
edquota – Edit user quotas for file system; setquota – Set disk quotas for file system; repquota – Summarize quotas for a file system; quotacheck – File system quota consistency checker; quotaon – Turn file system quotas on and off; /etc/fstab or /etc/vfstab – list of default parameters for each file system including quota status.
Consequently, no file could be larger than 2 32 − 1 bytes (4 GiB − 1). In many implementations, the problem was exacerbated by treating the sizes as signed numbers, which further lowered the limit to 2 31 − 1 bytes (2 GiB − 1). Files that were too large for 32-bit operating systems to handle came to be known as large files.
Bcachefs is a copy-on-write (COW) file system for Linux-based operating systems. Its primary developer, Kent Overstreet, first announced it in 2015, and it was added to the Linux kernel beginning with 6.7. [1] [2] It is intended to compete with the modern features of ZFS or Btrfs, and the speed and performance of ext4 or XFS.
