Can you send zpool status output and give exact config for ufs? Can you also give details which slices (starting and ending block) did you use for UFS and for ZFS? -- Best regards, Robert mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
