The 'inappropriate ioctl' just means that the FS doesn't support extended
attributes, so we can rule out the files being marked 'immutable' or
anything.  I don't think this rules out ACLs, but we've eliminated one
common cause for files being undeletable by root.

I agree with the advice to fsck to verify that the FS isn't corrupted.

Is this on the original or cloned system?  If the latter, what does it
look like on the original system?

It might also useful to verify the tar file, but I don't know tools for
doing this.
