I mean if we even suppose nothing bad happens because of it, is it worth risking to keep it? thank you. I wish there was a clear answer. There are two schools practised by server owners: - with swap space (partition or file) They see swapping as a symptom (of a problem, real or potential), and they treat it as a useful early warning device that gives them time to act. If prolonged or unattended, swapping may slow down the system and even end up in thrashing, which is close to a terminal state. - no swap space They are purists - when they set up a server for a specific purpose they know it (requirements, apps run, resources assigned) and they are in charge. No sissy swapping, they do not trust those kernel algos, etc. They know that out-of-memory kernel killer may terminate a process (perhaps not the one they would expect) in case of memory crunch, but they think they can live with it by closely watching system and app state indicators to prevent that from happening. In the end it comes down to owner's preferences. If in doubt, try with and without swap space and see how it works in your particular environment. jb ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

pkg_version says my ports need to be updated?
Clearly, I'm doing something wrong. :-) I thought I was using svn to keep my ports, src and docs up to date, but pkg_version seems to disagree. I'm running 9.1 and I've installed ports, src, and docs as part of my install. After that, I use subversion to (I thought) make sure everything was up to date. I ran these commands: /usr/local/bin/svn up /usr/src /usr/local/bin/svn up /usr/ports /usr/local/bin/svn up /usr/doc and then I ran: pkg_version -vIL = and it says needs updating (index has ...) on about 1 dozen items.

Instead of the MBR-style partition names (like da0s1a or da0a), GPT-style partition names (like da0p1) are being used. As known, they carry a UFS file system. Is the partition mechanism simplified here? No. It's a _different_ mechanism.
