Thread-topic: SGI Version 1 XFS on Linux



We have several older SGI hard drives we are trying to recover data from. However, since these drives came from an SGI Onyx running IRIX 6.2, it uses the older version 1 XFS file system. I can see the SCSI drive on my Linux box (CentOS 5.11) and I know data is on the drive, I can list out some of the info using dd, cpio or strings, but cannot copy the data off of it. I have tried using xfs_copy to a version 2 XFS partition, but it just converts the target partition to version 1, which I cannot mount. I have also looked at xfs_dump/restore, but those require mounted filesystems.


Is there any script or program or option I can use to copy the data off of the un-mounted SGI XFS partition. I’m guessing some combination of the cpio and dd, but I have not figured out the right combination yet.
