[Gluster-users] Problem with Glusterfs - taking over CPU time on clients
Hi, I have 7 clients on AWS in ELB and every of them is connected to glusterfs servers group of two. On clients, version of glusterfs is glusterfs 3.7.1 built on Nov 22 2015 17:39:20 and on server side both of servers have same glusterfs 3.6.2 built on Jan 22 2015 12:58:10 The major and urgent problem is the situation after disconnecting and connecting one of the servers, on one of the clients (and that is changing which one after few minutes) are overtaken with glusterfs process (all apache processes are on sleep in the same moment) which is responsible for rw session files. This is a very frequent job. Without disconnection, everything working except filling log files with a big amount of messages (probably incompatibility versions of glusterfs on servers and clients side why I tried yesterday to get the update for server side). Do anybody have a solution for this overtaking situation? Milos Kurtes, System Administrator, Alison Co. -------------- next part -------------- An HTML attachment was scrubbed...
