First of all, I do apologize for not being able to find the answer on my own. I tried searching hard, but found pretty much nothing.
When I start 'mongo' shell on my Ubuntu VPS, it tells me the following:
2014-12-17T19:48:02.624+0000 [initandlisten] ** WARNING: You are running in OpenVZ which can cause issues on versions of RHEL older than RHEL6.
2014-12-17T19:48:02.624+0000 [initandlisten]
2014-12-17T19:48:02.624+0000 [initandlisten] ** WARNING: /proc/sys/vm/zone_reclaim_mode is 1
2014-12-17T19:48:02.624+0000 [initandlisten] ** We suggest setting it to 0
2014-12-17T19:48:02.624+0000 [initandlisten] ** http://www.kernel.org/doc/Documentation/sysctl/vm.txt
I can not change the value in /proc/sys/vm/zone_reclaim_mode as it is telling me it can not be opened for writing. Of course, I stop the mongod service first.
So I'm kind of lost about where to search for a solution, as I'm a newbie to Linux. Does anybody know the answer or is able to point me to a right direction?
