Holla,
It seems, that it isn't possible to enable the SMART Automatic Offline Test anymore with 2.4.x (I tried 2.4.13 and 2.4.20).
And additionally: Enabling an already enabled Automatic Offline Test with 2.4.x disables it.
Switching back to 2.2.20 I was able to re-enable it.
I tried this with different tools: ide-smart, smartsuite, smartmontools and had a look at their sources, but they all use the same ioctl():
__u8 args[4] = {WIN_SMART, 0xF8, SMART_AUTO_OFFLINE, 0}; ioctl(fd, HDIO_DRIVE_CMD, &args);
The ioctl() returns no error, but it doesn't do anything:
root@darkside:~# uname -a Linux darkside 2.4.20 #1 Thu Dec 5 23:17:41 CET 2002 i686 unknown unknown GNU/Linux
root@darkside:~# ide-smart /dev/hdb | grep AutoOff OffLineStatus=130 {Completed}, AutoOffLine=No, OffLineTimeout=0 minutes root@darkside:~# ide-smart -1 /dev/hdb root@darkside:~# ide-smart /dev/hdb | grep AutoOff OffLineStatus=130 {Completed}, AutoOffLine=No, OffLineTimeout=0 minutes
and:
root@darkside:~# ide-smart /dev/hdc | grep AutoOff OffLineStatus=130 {Completed}, AutoOffLine=Yes, OffLineTimeout=38 minutes root@darkside:~# ide-smart -1 /dev/hdc root@darkside:~# ide-smart /dev/hdc | grep AutoOff OffLineStatus=130 {Completed}, AutoOffLine=No, OffLineTimeout=38 minutes
Booting 2.2.20 I'm able to enable AutoOffLine via ide-smart -1.
I searched through the archives but didnt find anything matching this...
Is this a known problem? Did the ioctl() change somehow? Am I able to work around it on a currently running 2.4 system?
And btw... Am I able to change the OffLineTimeout value somehow?
PS: Please CC: me in replies, since I'm not on the list.
