Обсуждение: PG under OpenVZ?
Hi! I've found an old thread on OpenVZ: (2008): http://archives.postgresql.org/pgsql-performance/2008-03/msg00076.php And a more recent question that scared me a bit: (2011): http://serverfault.com/questions/281783/running-mongodb-with-openvz On the PostgreSQL general mailing list, I've only found 54 results when searching for OpenVZ. I'm wondering if OpenVZ issimply unpopular, or not used at all for PG. What experiences do you have with OpenVZ? Any performance problems? We're buying bare metal to run our clusters on, and the supplier is late delivering the machines. They suggested lendingus a machine and run PostgreSQL under OpenVZ. When the real hardware is ready, we'd migrate the VZ over to the newphysical servers. Thoughts on this? I have no experience with OpenVZ itself, so if you have general comments about it's stability and/or performance, even unrelatedto PostgreSQL, I'd appreciate. Thanks! François

I run all my PG productions/tests servers on openvz, you just have to be careful to have swap activated, and SHMPAGES tuned, as well as SHMMAX. Otherwise it runs like a charm. -- Benjamin Henrion <bhenrion at ffii.org> FFII Brussels - +32-484-566109 - +32-2-3500762 "In July 2005, after several failed attempts to legalise software patents in Europe, the patent establishment changed its strategy. Instead of explicitly seeking to sanction the patentability of software, they are now seeking to create a central European patent court, which would establish and enforce patentability rules in their favor, without any possibility of correction by competing courts or democratically elected legislators."

We run several database clusters under openvz. I have nothing to report. openvz is pseudo-virtualisation. All the processes run under the host kernal and appear in the proc-table, and use the host systems filesystem and device drivers. they just see different filesystems and resource limits according to their vz. this basically means running the clusters under openvz is not radically different from running them all on the host system -- ⚂⚃ 100% natural

Running a small PG-Server for private purposes on openVZ. Cannot complain so far. Cheers, Frank
