Question about debugging the source of uevents

Hi,

I have a spare hard disk I don't touch the most of the time. Due to a
strange reason, a change uevent is triggered some random time of the day (like 4 or more times) and then, of course, udev apply the rules, being one of them a rule which runs vol_id which then wakes up my spinned-down hard disk (debugged with echoing a 1 to /proc/sys/vm/block_dump and udevadm monitor).

Well, what i want to know is if it's possible to know why the kernel
is triggering the uevent in the first place. Grepping the documentation of the kernel I don't see anything about it. I know I can just comment the watch line in /lib/udev/rules.d/60-persistent-storage.rules but I wanted to know more.

I'm using Archlinux which currently uses kernel 2.6.28.8 and udev 140.

Thanks in advance.

Does "monitor" show a kernel event, or only a udev event?

Any other events at the same time?

Are you running smartd?

Kay

I don't remember exactly (if I remember correctly, it was one uevent everytime). Here I attach the logs. Later I could tell you better. I will be more aware of that.

Yes, but I have smartd configured to ignore the hard disk if it's in standby. In syslog I have:
smartd[7004]: Device: /dev/sda, is in STANDBY mode, suspending checks

And thanks for answering so fast (and wasting your time too).

If there is no kernel event, if might be udev itself watching for possible changes done by userspace programs to the disk.

The "removing watch on '/dev/sda'" is my fault. I added this rule:
KERNEL=="sda*", OPTIONS-="watch", to /etc/udev/rules.d/99-user.rules , which I'm seeing it doesn't have the effect I wanted.

I'm running udevadm monitor right now, so if you need that information I will mail it to you later. Thanks.

There is no -= thing, you need to use "nowatch".

FWIW, on my system with smartmontools 5.38,

smartctl -a /dev/sda => open("/dev/sda", O_RDWR|O_NONBLOCK)
smartctl -d ata -a /dev/sda => open("/dev/sda", O_RDONLY|O_NONBLOCK)

It behaves the same in both cases. Tom, you might try adding "-d ata" to /etc/smartd.conf to see if it works around your problem.

Thanks Jim! That's even better. Now I don't have to use the nowatch udev rule. With '-d ata' parameter the uvent isn't triggered (and I straced it too).
