[Pacemaker] Filesystem resource killing innocent processes on stop

[Nikola Ciprich]

Hi,

I noticed very annoying bug (or so I think), that resource-agents-3.9.5
in RHEL / centos 6 Filesystem OCF resource seems to be killing completely
unrelated processes on shutdown although they're not using anything on mounted filesystem...

unfortunately, one of processes very often killed is sshd :-(

here's example of the log:

Filesystem(virt-fs)[4803]:      2015/05/17_21:59:48 INFO: sending signal TERM to: root      3606     1  0 Feb12 ?        S<s    0:01 /sbin/udevd -d

while unmounting /home/cluster/virt directory.. what is quite curious, is, that last killed process seems to be
Filesystem resource itself..

before I dig deeper into this, did anyone else noticed this problem? Is this some known
(and possibly already issue)?

thanks a lot in advance
