[Bug 475329] [NEW] High CPU and DISK load on mounting NTFS with hibernated WinXP

[Hedgehog_57]

Public bug reported:

Binary package hint: ntfs-3g

System: IBM Thinkpad T61P
OS: Dual boot WinXP SP3/Ubuntu 9.10
Reproductable: yes

Boot to winXP.
Hibernate it.
Boot Ubuntu.

menv at hedgehog-book:~$ iotop -o

   COMMAND
------------------
As you can see no process use the disk, but something reads
40 M/s

This is top output. Nothing interesting.

And now the problem:

menv at hedgehog-book:~$ ps -Af|grep winnt
root 26027 474 0 17:15 ? 00:00:00 mount -a -t ntfs -o defaults /dev/sda1 /media/winnt
root 26028 26027 0 17:15 ? 00:00:00 /sbin/mount.ntfs /dev/sda1 /media/winnt -o rw 
menv 26030 28807 0 17:15 pts/0 00:00:00 grep winnt 

menv at hedgehog-book:~$ ps -Af|grep winnt 
menv 27223 28807 0 17:15 pts/0 00:00:00 grep winnt

menv at hedgehog-book:~$ ps -Af|grep winnt
menv 27591 28807 0 17:15 pts/0 00:00:00 grep winnt

menv at hedgehog-book:~$ ps -Af|grep winnt
menv 27821 28807 0 17:15 pts/0 00:00:00 grep winnt

menv at hedgehog-book:~$ ps -Af|grep winnt
root 28210 474 0 17:15 ? 00:00:00 mount -a -t ntfs -o defaults /dev/sda1 /media/winnt
root 28211 28210 0 17:15 ? 00:00:00 /sbin/mount.ntfs /dev/sda1 /media/winnt -o rw
menv 28213 28807 0 17:15 pts/0 00:00:00 grep winnt

This is infinite process. One mount die and new one is created.

This how to stop it. After this high CPU and DISK utilization are off.
--------------
menv at hedgehog-book:~$ sudo mount /media/winnt
Windows is hibernated, refused to mount.
Failed to mount '/dev/sda1': Operation not permitted
The NTFS partition is hibernated. Please resume and shutdown Windows
properly, or mount the volume read-only with the 'ro' mount option, or
mount the volume read-write with the 'remove_hiberfile' mount option.
For example type on the command line:

            mount -t ntfs-3g -o remove_hiberfile /dev/sda1 /media/winnt

menv at hedgehog-book:~$ sudo mount -o ro /media/winnt
menv at hedgehog-book:~$ sudo umount /media/winnt
-------------
The second NTFS partition (SDA5. not with hiberfil.sys file) is mounted normally during boot process.
