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.
