When I try to mount a disk from our SGI Origin 200
machine under Linux (Fedora Core 5), I get the following error message:

# mount /dev/sda1 /mnt/sgi
mount: Function not implemented

The partitions are found during boot:

...
SCSI device sda: 143374738 512-byte hdwr sectors (73408 MB)
sda: Write Protect is off
sda: Mode Sense: 9f 00 10 08
SCSI device sda: drive cache: write back w/ FUA

# fdisk -l /dev/sda

Disk /dev/sda (SGI disk label): 255 heads, 63 sectors, 8924 cylinders
Units = cylinders of 16065 * 512 bytes

Bootfile: /unix
----- Directory Entries -----

The only thing that gets logged during the mount is:

SGI XFS with ACLs, security attributes, large block numbers, no debug
enabled
SGI XFS Quota Management subsystem


How do I determine which of the requirements
listed in:

http://oss.sgi.com/projects/xfs/faq.html#useirixxfs

that hasn't been fulfilled?
