recover xfs with v1 dirs on linux?

["Honza Fikar" <j.fikar@xxxxxxxxx>]

Hi everybody,

I want to recover old SGI Irix xfs disks, but I don't have any more the old
hardware. I was able to copy the xfs partition in a file with dd and I could
run xfs_recover, xfs_check and xfs_ncheck, which gives me the filenames. But
I was not able to mount this file. Kernel 2.6.17 gives "Function not
implemented", while 2.6.5 mounts, but the disk looks empty.

I think the reason is "v1 dirs":

file img4.xfs
img4.xfs: SGI XFS filesystem data (blksz 4096, inosz 256, v1 dirs)

Is there a way to get the files? I have the innode numbers and filenames as
an output of xfs_ncheck:
....
947364 abc/MIXDUM/MD110/20K/step9/dynrt.out.gz
184821 aa/Monteal/fmd3kev-45K/cluster.I.076.gz
1286273 abc/MIXDUM/MD111/250K/step10/dyn5.f1.gz
...


Thank you,
Jan
