Hi folks, I have a 3 node gluster/web/db cluster running a Wordpress site . This morning one of the nodes is under very high load and the mounted gluster partition is inaccessible. Attempts to reboot that node have failed with the server seemingly hung/blocked. Has anyone else experienced this or can give any pointers in how to diagnose the cause of gluster going awry?

Well, that's "funny", because the exact same thing happened to me this morning, except that I could hard reboot the machine, and it got up and running normally again. But the symptoms you describe are oddly similar, and strangely simultaneous. Le 08/05/2015 10:36, Alun James a ?crit :> Hi folks, > > I have a 3 node gluster/web/db cluster running a Wordpress site .

Similar to this one... When running Wordpress update, the load on the server goes through the rough due to Gluster, site is very unresponsive during this time. How can I improve the performance?
