The problem is, when it happened that one of replica servers hung, it caused the whole glusterfs to hang. Could you please drop me a hint, is it expected behaviour, or are there any tweaks and server or volume settings that might be altered to change this? Any help would be appreciated much.<br><br><br>--<br>Best Regards,<br><br>Seva Gluschenko<br>CTO @ <a target="_blank" rel="noopener noreferrer" href="http://webkontrol.ru/">http://webkontrol.ru</a></signature><br> </div></body></html>
