You can sometimes run into bugs and issues if your home directory is partitioned in XFS, BTRFS, or ZFS. Aside from the brave decision to use the Rust programming language, Stratis aims to provide Btrfs/Zfs-esque features using an incremental approach. For more information see the next4 project. Kevin discusses how features such as performance and journaling can be used to distinguish file systems. Theodore Ts'o, a maintainer for Ext3 and later, Ext4, has stated that he sees Btrfs as a better way forward than continuing to rely on the ext* technology. This is another Linux interview question. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robus. It is expected to replace ext4 as the default file system in Linux. I found that xfs and ext4 both performed similarly, with ext4 just a few percent faster; and I found that adjusting the mount options only gave small improvements, except for the barrier options. O sistema de arquivos ext4 é compatível com o ext3 e ext2 Isto irá melhorar o desempenho já ligeiramente, porque alguns novos recursos do ext4 também pode ser usado com ext3 e ext2, tal como o novo algoritmo de alocação de blocos. You might also wonder whether ext4 is still in active development at all, given the flurries of news coverage of alternate filesystems such as btrfs, xfs, and zfs.

Btrfs(B-tree file system 또는 Butter file system, Better F S)는 파일 시스템 가운데 하나로 현재 페이스북의 크리스 메이슨이 개발을 지휘하고 있다. In 2008, Ts'o stated that although ext4 has improved features such as being much faster than ext3, it is not a major advance, it uses old technology, and is a stop-gap; Ts'o believes that Btrfs is the better direction, because "it offers improvements in scalability, reliability, and ease of management". Special features of ext4, XFS, and Vtrfs are examined. In ext2, ext3, and ext4 (when the 64bit feature is not enabled), the block group descriptor was only 32 bytes long and therefore ends at bg_checksum. hier würde ich sagen, dass der zusätzliche Nutzen den minimalen Performanceeinschnitt rechtfertigt.
