I created a fresh XFS filesystem in a SCSI disk, with xfsprogs version 2.6.18.

It is so strange... General data: x86 P-IV 2.5 GHz 512 MB RAM The filesystem was onto a MAXTOR 70 GB SCSI disk, connected to Adaptec AIC79XX PCI-X SCSI card. The other filesystem containing files over XFS is a RAID0 over two identical IDE disks. If you need further information, like .config or so, please do not hesitate to ask.
