XFS uses barriers by default as well. However, the use of barriers is wholly dependent on the storage back end. WRT to systems with BBWC, either on an HBA RAID card or a SAN array, barriers should be disabled for performance reasons. With BBWC, flushing the cache often ruins write performance and doesn't increase data safety. > By the way, detailed mount options should always be considered when comparing > file systems. Depends on what features are being compared, but in general I agree. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
