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...

Are you sure it has an XFS file system on it?

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 ...
