Fedora 12 Mounting Realtime XFS (from Direct TV DVR HR22 SATA Drive)
 

I am attempting to mount my Direct TV DVR (HR22) SATA Drive using Fedora 12 x86_64 using the following command:

mount -t xfs -o rtdev=/dev/sdf3 /dev/sdf2 hr22

mount: Function not implemented

The output of BLKID is:
/dev/sdf2: UUID="f108a0c1-ded6-460c-b3f9-db9d66162c49" TYPE="xfs"

The output of fdisk /dev/sdf is:
Device Boot Start End Blocks Id System
/dev/sdf1 1 66 530113+ 82 Linux swap / Solaris
/dev/sdf2 67 2025 15735667+ 83 Linux
/dev/sdf3 2026 121601 960494220 83 Linux


I am able to mount this using MSFLive.org LIVECD/USB:

I must have something wrong with my installation in some what so that i can't mount a Realtime XFS Share in Fedora 12.

I have not been able to find any help after days of googling..

Any suggestions?

Thanks,

Update - Knoppix Works
 

I am able to mount my drive in Knoppix 6.2 x86 w/o problem.. Any Suggestions why Fedora has a problem with realtime XFS?

Solution:

I recompiled the kernel with XFS Realtime Enabled
