Package: mongodb-server Version: 1:2.4.3-1 Severity: normal When mongodb is launched on a NUMA system, the following log is generated, which can be visible on subsequent mongo connections:
seoul# mongo test MongoDB shell version: 2.4.4-pre- connecting to: test Server has startup warnings: Thu Jul 4 09:32:29.471 [initandlisten] Thu Jul 4 09:32:29.471 [initandlisten] ** WARNING: You are running on a NUMA machine. Thu Jul 4 09:32:29.471 [initandlisten] ** We suggest launching mongod like this to avoid performance problems: Thu Jul 4 09:32:29.471 [initandlisten] ** numactl --interleave=all mongod [other options] Thu Jul 4 09:32:29.471 [initandlisten] The official documentation suggests (http://docs.mongodb.org/manual/administration/production-notes/#production-numa) to launch mongod on NUMA systems differently, as mentioned above. Though, /etc/init.d script does neither support it automatically, nor has some /etc/default/mongo-configurable setting to allow this. Seems like there is some work on it ongoing upstream and might be fixed by 2.5+, see https://jira.mongodb.org/browse/SERVER-6008. But it seems to me, this issue can be important for pre-2.5 releases as well, and might need to be backported and fixed on previous releases. -- System Information: Debian Release: jessie/sid APT prefers testing APT policy: (990, 'testing'), (500, 'stable-updates'), (500, 'stable'), (480, 'stable'), (450, 'unstable'), (400, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.9-1-amd64 (SMP w/2 CPU cores) Locale: LANG=ru_RU.UTF-8, LC_CTYPE=ru_RU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages mongodb-server depends on: ii adduser 3.113+nmu3 ii libboost-filesystem1.49.0 1.49.0-4 ii libboost-program-options1.49.0 1.49.0-4 ii libboost-system1.49.0 1.49.0-4 ii libboost-thread1.49.0 1.49.0-4 ii libc6 2.17-6 ii libgcc1 1:4.8.1-2 ii libgoogle-perftools4 2.0-2 ii libpcre3 1:8.31-2 ii libpcrecpp0 1:8.31-2 ii libsnappy1 1.1.0-1 ii libstdc++6 4.8.1-2 ii libv8-3.8.9.20 3.8.9.20-2 ii mongodb-clients 1:2.4.3-1 mongodb-server recommends no packages. mongodb-server suggests no packages. -- Configuration Files: /etc/mongodb.conf changed [not included] -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
