Greetings, I have a 500Gig hdd with and XFS filesystem created by openfiler (which strangely switched from lovely CentOS for reasons best known to them). I fired up a Centos box with this hdd. I then did yum install kmod-xfs.i686 xfsdump.i386 dmapi xfsprogs and it wnt through. But when I try to mount this volume mount -t xfs /dev/hdd1 /mnt/test I get the error: mount: /dev/hdd1 already mounted or /mnt/test busy I then try xfs_admin -l /dev/hdd1 The results being: xfs_admin: unexpected XFS SB magic number 0x00000000 xfs_admin: read failed: Invalid argument xfs_admin: data size check failed cache_node_purge: refcount was 1, not zero (node=0xa058670) xfs_admin: cannot read root inode (22) label = "(null)" Sure I'm missing something very basic here... Can somebody point my mistake? and some clues to solve this problem... TIA Regards Rajagopal

What does the following report: file -s /dev/hdd1 And what happens when you just do: mount /dev/hdd1 /mnt/test The output of xfs_admin looks like the output you get if the file system is ext2/ext3 ...
