Server PHP Sites goes down
Our VM’s which are in Act-Act Cluster with Apache Application Server hosts 22 PHP websites. Apache is behind nginx and for replication of data we use gluster cluster of 2 peers. Actually, we had 3 node cluster but because of some issue, we dis-connected 3rd node and brick is dis-connected now for gluster. Also we removed the configuration of this node from nginx.
Our sites GOES DOWN every 3-4 days due to heavy load on gluster. We have 16GB RAM over each CentOS 7.x VM’s with 8vCPU’s. Gluster is in replicated mode with 3 bricks out of which one is dis-connected. We are using FUSE client for Gluster.
Can you please help to tell what to look for in order not to have downtime for our sites? I am new in Gluster. I did some performance tuning of Gluster Volumes but seems its not working. I am ready to share more information if you need.
