just a confirmation for Emmanuels remark about XFS for Fileservers with a greater volume,
for those who need specs for a file system with a reasonable storage size ...
In case you do not reach the limits where a cluster file system is needed ( like GPFS or Lustre )
XFS imay be the linux file system of choice
- fortunately it is supported by Redhat again, like Emmanuel mailed before, and it is very well flight tested for big storages in commercial environments
( disclaimer: naturally for those storages that are not completely based on commercial vendors own fileystems like WAFL or OneFS
- xfs is journaled which guarantees within limits data transfer integrity.
( against data loss for big storages you need to protect on raid level or with a backup )
-Even with journaling on and on the same device like the file system i can confirm
that a "typical" speedup on a "big storage" with XFS is 30% compared to other classic linux filesystems
-exceptions to this "rule of thunb"
- There are linux filesystems that are more tuned to "many small files" using btrees+ (balanced bayer trees
-specialized file systems for a given purpose, like database pattern optimized file systems from a big database venodr ;-)
or filesystems tuned for USB sticks. The infos given relate to "file server" usage
