</span> upgraded to 3.7.13 from 3.7.11 using yum, while at
least one VM is running :-)<br>
on all 3 servers, one by one:<br>
<br>
yum upgrade<br>
systemctl stop glusterd <br>
than killed glusterfsd processes using kill <br>
and systemctl start glusterd<br>
<br>
then next server....<br>
<br>
after this we tried to restart VM, but it failed, because
we forget to restart libvirtd, and it used old libraries,<br>
I guess this is point where we got this problem.<span
