I was wondering if you have seen anything like this? We've talked to Gluster support, but they appear to be washing their hands of it now....

This nagios script will require to have the gluster client component installed on the Nagios server. Is that correct? Hello, Ian.

I have been using glusterFS on ec2 for a while. It worked great for us except that it leaked memory and reached the RAM limit and started swapping. Every 2-3 days i had to kill and restart it. I used gluster 2.0.2. I had no idea gluster current version reached 3.0. Just upgraded our servers. Things look smooth but need to monitor over the next 2-3 days.  Thanks Ian for the post.

I've fowarded this to our director of engineering and I'll follow up to see if we can get it included in a release. I'd like to get you some tee shirts and hats as a thank you, please get in touch.

"performance/stat-prefetch" may be useful depending on what your apache is serving. If you are serving PHP pages which read the contents of folders (e.g wordpress/phpbb) then it could make a big difference. However, I've had big problems with "performance/stat-prefetch" and apache and have filed a bug here;

Once those problems are cleared up in a future release it may be worth taking another look at performance/stat-prefetch

What do you mean by "B to A cross replication"?
