Re: [dm-devel] sg_persist triggers block kernel event ???



Dne 3.5.2014 22:12, Christophe Varoqui napsal(a):
Hi list,

I observe this on a debian 7.5 server with a udevadm monitor running in the
background :

# sg_persist -n -k /dev/sdbh
   PR generation=0x0, there are NO registered reservation keys


Whoever opens device in 'read-write' mode and then closes device triggers udev change event. (udev rescans whatever has changed on device after this)

That's how it works for many years already.
It's not a bug and some even says it's a feature....
