From the ports page I noticed that the ports version is approximately 14 months old: http://www.freebsd.org/cgi/ports.cgi?query=asymptote I tried to contact the maintainer via email, but got no response. What would be the correct procedure for trying to get that port updated? 1. Somehow get in contact with the maintainer. How? (I tried.) A non-responding maintainer may be for any number of reasons including having lost all interest, but sometimes they're just temporarily unavailable (on holiday, busy with other things ...) and will get back to it later. 2. Try to become a maintainer. How? Step one would be to try bringing the port up to date yourself, sometimes it is as easy as editing the Makefile, changing the version and running make makesum to update the checksums. Sometimes the patches need to be adjusted in which case much depends on how much patching was needed in the first place. In the case of asymptote it looks like the only patch is adjusting the path to exampledir in Makefile.in which ought to be pretty easy to handle. The porters handbook has a lot of useful information on what to do when things get tricky. If you succeed in bringing the port up to date then your problem is solved (you have an up to date version) and if you use send-pr to submit the changes to bring it up to date then there's a good chance that you'll solve the same problem for everyone else who may want it. 3. Something else? Wait for someone else to do it.

The iso8859 encodings are 256 character maps, the UTF-8 encoding covers the entire million character range of unicode (or iso10646 which amounts to the same thing) how well it displays depends on the font being used. This one has pretty good coverage. -misc-fixed-medium-*-*-*-*-140-*-*-*-*-iso10646-* There's a wonderful file around called UTF-9-demo.txt produced by Markus Kuhn which shows off the capability of UTF-8 pretty well, and tests your font support unmercifully (the font above can cope with the whole document, and an up to date urxvt handles the alignment correctly). There is a great deal to be said for adopting unicode by default, and generally in the form of UTF-8. I regard the iso8859 encodings as basically obsolete. Unicode has it's faults, but it is the best general purpose encoding system available.

Having negative free space will prevent non root users from writing data, but that will be returned to the applications as error returns to write calls not held in write buffers. Check with df -h for _no_ negative values before rebooting the system into SUM. I'm not sure if the write buffers can survive a shutdown. They can't but they're not connected with negative free space reports. A normal shutdown will flush all the buffers. I'm still able to issue sudo, so using sudo rm -r I was able to free up 25GB...but still, /bin/sh, ls, clear all seg fault and su doesn't work and switching consoles doesn't let me log in. That sounds that somehow calling programs (executing / forking) is not working properly anymore. As this is one of the most fundamental mechanisms of the systems, it's hard to believe that this can be triggered through a port update... More likely one of the shared libraries they all use has been overwritten. Updating ports certainly shouldn't be able to do this though.

What's the best way to increase the size of /tmp ? Could I simply remove it and create a symbolic link ln -s to say /usr/tmp instead (where I have several hundred GBs free)? That is a BAD IDEA(tm)! There are appliations that assume /tmp, /var/tmp, and /usr/tmp are _distinct_ directories. They will create files _with_the_same_name_ in two of those 'temp' locations, expecting them to be unique.o /usr/tmp usually does not exist so creating it and symlinking /tmp to it is OK. It _is_ OK to symlink /tmp to 'somewhere else', with the caveat that it should be on the '/' filesystem -- one may need it in single-user mode befoe other filesystems are mounted. You can 'live dangerously' and symlink to a dir on a different filesystem and _probably_ not have problems. A null mount would be a safer way of pushing /tmp onto /usr or indeed any other filesystem - that way when the null mount fails the mount point is still a directory. There's really no point in linking it elsewhere on the same filesystem. -- Steve O'Hara-Smith | Directable Mirror Arrays C:WIN | A better way to focus the sun The computer obeys and wins.|licences available see You lose and Bill collects. |http://www.sohara.org/ ___ 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

There are many static pages, but there is also a php-mysql forum that generates pages on the fly. It accounts for about half of the traffic. I've always used ufs but am wondering if switching to zfs would make sense. This stats page might answer some of your questions: http://www.stovebolt.com/stats/ Basically traffic is steady but it's busiest in the evenings (US time zones) Other considerations may come into play - how big is this filesystem (number of files, maximum number of entries in a directory, volume of data) ? Are there many users needing to be protected from each other ? What about archives ? snapshots ? growth ? churn ? uptime requirements, disaster recovery time ? I don't even know where to begin. There's about 15G of data on the server. OK I would say there's no pressing reason to consider ZFS for this purpose. You'd save a bit of time in crash recovery with no fsck going on, and perhaps the checksum mechanism would give some peace of mind - but really in 15GB silent corruption is a very slow process - now if it were 15TB ... last pid: 40369; load averages: 0.01, 0.03, 0.00 up 104+09:33:44 13:14:49 137 processes: 1 running, 136 sleeping CPU: 0.7% user, 0.0% nice, 0.1% system, 0.0% interrupt, 99.2% idle Mem: 229M Active, 6108M Inact, 1056M Wired, 15M Cache, 828M Buf, 514M Free Swap: 16G Total, 28K Used, 16G Free OTOH you have plenty of memory lying around doing nothing much (6108M inactive) so you can easily support ZFS if you want to play with it's features (the smooth integration of volume management and filesystem is rather cool). The system is not being stressed. If by users, you means shell accounts, there's two, so that's not really an issue. OK so no need for fancy quota schemes then. Uptime is not an issue. The owners have repeatedly said if the site is down for two days they don't care. (The forum users don't feel that way though!) We've had one disaster (hard drive failure and raid failed while I was on vacation), and it took about 36 hours to get back online, but that was 10 years ago. The site doesn't go down - it's running on FreeBSD. :-) It sounds like you have backups or at least some means of restoring the site in the event of disaster so that's all good. If there was a pressing need to be able to get back up fairly quickly and easily I'd be suggesting ZFS in RAID1 with a hot swap bay in which a third disc goes, attached as a third mirror, periodically split it off the mirror take it off site, and replace it with the one that's been off site. There's really nothing here that's pushing you in any particular direction for a filesystem, at 15GB if performance ever becomes a problem a RAID1 of SSDs with UFS would make it fly probably into the hundreds of hits per second range. -- Steve O'Hara-Smith | Directable Mirror Arrays C:WIN | A better way to focus the sun The computer obeys and wins.|licences available see You lose and Bill collects. |http://www.sohara.org/ ___ 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

Lesson from this - don't bother setting primarycache=metadata. With that puzzle gone testing and tuning becomes more useful: Enabling prefetch made a huge difference to the per char sequential read, but didn't really change anything else. Indeed this test is now CPU limited in bonnie - that'll do. Rebooting with zfs.cache_flush_disable=1 made everything faster. Block writes and reads maxed out the discs at around 110MB/s and 200MB/s respectively - pretty close to the raw disc speed. Rewrite nearly doubled in speed too.

ZFS bonnie puzzlement
Hi, I've been looking at the performance of my new NAS box - built using a Jetway JNF99FL-525 with 4GB of 1066 DDR3 and a pair of 2TB Samsung F4 drives in a mirror. It all works but the performance reports are puzzling Running bonnie -s 8192 - reports character and block write times of around 66MB/s which is consistent with what zpool iostat -v and systat -v are showing me. Read performance OTOH is strange, zpool and systat both reporting consistently an aggregated read speed of around 120MB/s during the block read tests (which seems a bit slow for the drives - and indeed systat reports the drives at less than 50% utilisation) but bonnie is only reporting 35MB/s, I see similar discrepancies with simple dd block reads to /dev/null, in which case my stopwatch agrees with dd. I made some more bonnie tests on the boot SSD - there everything is as expected systat and bonnie agree and the disc gets pushed to 90-100% utilisation with write speeds over 100MB/s and read speeds over 250MB/s. Also a dd of the raw drive (read only of course) runs the drives up to around 130MB/s easily - dd and systat agree about the speed. First up can anyone explain the discrepancy between bonnie and zpool/systat for the XFS pool ? Secondly can anyone suggest a reason that I can't seem to get the drives above 50% reported utilisation on reads ? -- Steve O'Hara-Smith | Directable Mirror Arrays C:WIN | A better way to focus the sun The computer obeys and wins.|licences available see You lose and Bill collects. |http://www.sohara.org/ ___ 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
