Perhaps you can find something more > contemporary that can help you? pretty good summary, but I take issue with the XFS summary statement, "If you really like to tweak your system to meet your needs, XFS is a great way to go.". XFS requires no tweaking at all, just `mkfs.xfs /dev/vg_bigdata/lvwhatever` and mount and go. Its not suitable as the root file system for CentOS (mostly because Anaconda doesn't know how to set it up), but for data volumes, its king. only caveat is, the system MUST be 64bit, and you should have a fair amount of RAM to ensure xfs_check can handle the bajillions of files and links likely to accumulate on larger volumes. -- john r pierce 37N 122W somewhere on the middle of the left coast
