  Hi Bryan,

  Please tell. I have to replace our old Sun Enterprise fileserver
  (solaris8), which does NFS and Samba (homedirectories, projects file
  space).  It will be x86 hardware, but I'm looking for the best filesystem
  for the job (let's say one terabyte). It has to have quota and ACL support.

  I'm doing CentOS on servers these days, but I presume ext3 is not the
  best choice in this case. Previous postings of yours suggest XFS is the
  way to go. However, it seems hard to find an enterprise class linux
  distro with XFS incorporated? And how does a FreeBSD solution compare
  to linux/ext3 or linux/xfs?

  What are the considerations in case of a NAS filer instead of a raid-box
  connected to hostmachine?

  Regards,
