Hi All,
    I noticed that sometime udev may receive a time-out message during 
activating osd after rebooting system. Sth like that:

Oct 11 07:15:40 cvknode2 udevd[965]: timeout: killing '/usr/sbin/ceph-disk 
activate-journal /dev/sdb2' [1834] Oct 11 07:15:40 cvknode2 udevd[965]: 
'/usr/sbin/ceph-disk activate-journal /dev/sdb2' [1834] terminated by signal 9 
(Killed)

It will cause device or partition mounted on both directory, the right one and 
tmp one.

/dev/sdb1 477630464 218421512 259208952 46% /var/lib/ceph/tmp/mnt.rzE_fa
/dev/sdb1 477630464 218421512 259208952 46% /var/lib/ceph/osd/ceph-2

When I commented out all in the /lib/udev/rules.d/95-ceph-osd.rules and 
rebooted system, there would be no timeout and osd could be activated normally. 
I have 2 questions:
1. What caused udev receive timeout message.
2. Can I just commented out all in the /lib/udev/rules.d/95-ceph-osd.rules, 
Cause calling activate-all can do activate osds, why need extra calling 
activate and activate-journal?

Best regards,
