[gentoo-user] Questions about wine
I'm looking at getting wine going for a Windows-only app. Some questions... 1) The latest ebuild wine-1.6_rc4 (unstable) apparently should have the prelink USE flag. http://www.gentoo.org/doc/en/prelink-howto.xml talks about a cron job to run prelink every so often, which seems like the wrong approach. Wouldn't it make more sense to run it right after emerge? Are there any problems with running prelink on all programs? 2) I'm hazy about some of wine's USE flags... are opencl and opengl and osmesa recommended? My onboard video chip (according to lspci) is 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09) 3) LINGUAS supports both en and en_US. Is it recommended to enable both? -- Walter Dnes waltd...@waltdnes.org I don't run desktop environments; I run useful applications

Mine is mostly videos and some smaller amount of pics. 1 Tb is 125Gb? 1Tb is 1,000Gb or so. I would also be concerned about the cost of one that large too. Confused.

Re: [gentoo-user] syslog-ng segfaults

As for me, first I updated syslog-ng, then I issued '/etc/init.d/syslog-ng reload' (by mistake, instead of 'restart'), and then 'restart' as I should. Then, just when syslog-ng was restarting, the segfault happened. I also noted that restarting syslog didn't seem to solve the problem. I do think Adam's reasoning makes sense, but there must be something else that needed to be restarted as well. Same behaviour here. In my case with an lsof | grep libsyslog-ng I see in the physical host hp-systray from hplip was still using the old libsyslog-ng.so, so killing that and a restart of syslog-ng service stops the segfault lines.

SSDs, VM SANs RAID - WAS Re: [gentoo-user] SSD partitioning and migration

Yes, the I/O would be faster, although how significant totally depends on your workload pattern. The bottleneck would be the LAN, though. The peak bandwidth of SATA is 6 GB/s = 48 Gbps. You'll need active/active multipathing and/or bonded interfaces to cater for that firehose. Next is RAID...

So I could maybe start using RAID6 (would survive two simultaneous disk failures), and not lose so much available storage (50% with RAID10)? If you're using ZFS with spinning disks as its vdev 'elements', resilvering (rebuilding the RAID array) would be somewhat faster because ZFS knows what needs to be resilvered (i.e., used blocks) and skip over parts that don't need to be resilvered (i.e., unused blocks).

Interesting... Another alternative for performance is to buy a bunch of spinning disks (let's say, 12 of them 'enterprise'-grade disks), join them into a ZFS Pool of 5 mirrored vdevs (that is, a RAID10 a la ZFS) + 2 spares, then use 4 SSDs to hold the ZFS Cache and Intent Log. The capital expenditure for the gained capacity should be cheaper, but with a very acceptable performance. Rgds, --

So the answer is smaller disks in order not to accumulate so much crap! ;-) Best regards Peter K I have to say, most of mine is useful stuff. I have smaller files that show the wiring for my car speaker system. I have documents that I sent to Social Security and State offices concerning my disability. I also have some financial info, encrypted of course, stored here. My smaller stuff is important to keep. My larger stuff is videos and camera pics. Just as examples: 9.4G/home/dale/Desktop/Music 1.1T/home/dale/Desktop/Videos 16G /home/dale/Desktop/Documents/Camera-pics 5.2G/home/dale/Desktop/Documents/Kathie-camera 4.4G/home/dale/Desktop/Documents/Recipes That's just a example. You may notice, videos is by far the largest thing I have tho. It takes up a LOT of space. I may could clean up some of that stuff a bit but it wouldn't be much. I generally store stuff in a temp location until I know if I need it long term. Stuff like exploded views of my washing machine. When I know it is the right one for my washing machine, I move it to a permanent location. If it turns out to be the wrong one or I can't fix the appliance, I chunk the appliance and then trash the files too. I also keep the last two versions of sysrescue for my USB stick. That reminds me, I need to test the latest one to make sure it works, when I reboot again. :/ Yea, I'm one weird cookie. lol Dale :-) :-) -- I am only responsible for what I said ...

A known, good kernel is not much help if your root filesystem is damaged,
although I do make sure I always have at least one such kernel in /boot.
One of the benefits of booting sysrescd this way is that it is a *lot*
