Hi What is your device path which represents your ntfs partition /dev/centos7/test-pure-ntfs or /dev/mapper/centos7-test--pure--ntfs or /dev/mapper/centos7-test--pure--ntfs1 ?
Please post the outputs of (as root) : dd if=/dev/DEVICE count=1 | od -t x1 | head -n 1 replacing DEVICE by centos7/test-pure-ntfs etc. Jean-Pierre xiucai wrote: > hi, > > my steps are: > 1, lvcreate, make a lv, named test-pure-ntfs, vg is > centos7(consisted of sdb); > 2, virsh attach-disk, attach test-pure-ntfs to an > VM(Windows-Server2008R2x64); > 3, make this new disk online and format it(MBR+NTFS); > 4, then this disk can rw normally within VM; > 5, ntfs-3g, mount test-pure-ntfs on a existed path(/mnt/ntfs/), but > failed! > > so, why? > do not ntfs-3g support my case? > > ==========here are parts of my actions========== > [root@localhost mnt]# mount -t ntfs-3g /dev/centos7/test-pure-ntfs > /mnt/ntfs/ > NTFS signature is missing. > Failed to mount '/dev/mapper/centos7-test--pure--ntfs': invalid parameter > The device '/dev/mapper/centos7-test--pure--ntfs' doesn't seem to have a > valid NTFS. > Maybe the wrong device is used?
