[gentoo-user] RESTRICT_PYTHON_ABIS=3.* - what's that?
Hi, the recent dev-python/matplotlib-0.99.1.1-r1 contains the statement RESTRICT_PYTHON_ABIS=3.* Does anybody know what that means? Does it indicate that this package needs Python-3.x ? (Reason, it fails here to install.

The drives are new, but contain random data left over from some speed and reliability tests I did. I don't care about keeping the current 'data', as long as when the array is reliable later. Can I use the --assume-clean option with mdadm and then expect it to keep working, even through reboots? Or is this a really bad idea? Many thanks, Joost Roeleveld Hi all, Many thanks for all the input, I did wait the 20 hours, but when it was finished, the performance was still slow. And trying out different options for the array didn't actually help. Thanks to the thread 1-Terabyte drives - 4K sector sizes? - bar performance so far I figured out the problem (4KB sectors). After changing the partitions to use sector 64 as start (as opposed to 63) a build of the array should only take 6 hours. Hopefully, the raid-array will also show a better performance when this is finished. -- Joost Roeleveld

Looking at the original partition put on just using default values it had the starting sector was 63 - probably about the worst value it could be. As a test I blew away that partition and created a new one starting at 64 instead and the untar results are vastly improved - down to roughly 20 seconds from 8-10 minutes. That's roughly twice as fast as the old 120GB SATA2 drive I was using to test the system out while I debugged this issue. That's good to hear. I'm still a little fuzzy about what happens to the extra sectors at the end of a track. Are they used and I pay for a little bit of overhead reading data off of them or are they ignored and I lose capacity? I think it must be the former as my partition isn't all that much less than 1TB. As far as I know, you shouldn't worry about it. The head/track/cylinder addressing is a relic of an older day. Almost all modern drives should be accessed via LBA. If interested, take a look at the wikipedia entry on Cylinder-Head-Sector and Logical Block Addressing. Basically, you are not losing anything. Cheers, W -- Willie W. Wong ww...@math.princeton.edu Data aequatione quotcunque fluentes quantitae involvente fluxiones invenire et vice versa ~~~ I. Newton Hi, Yeah, a little more study and thinking confirms this. The sectors are 4K. WD put them on there. The sectors are 4K. Just because there might be extra physical space at the end of a track doesn't mean I can ever use it. The sectors are 4K and WD put them on there and they've taken ALL that into account already. They are 4K physically with ECC but accessible by CHS and by LBA in 512B chunks. The trick for speed at the OS/driver level is to make sure we are always grabbing 4K logical blocks from a single 4K physical sector off the drive. If we do it's fast. If we don't and start asking for a 4K block that isn't in a single 4K physical block then it becomes very slow as the drive hardware/firmware/processor has to do multiple reads and piece it together for us which is slow. (VERY slow...) By using partitions mapped to sector number values divisible by 8 we do this. (8 * 512B = 4K) The extra space at the end of a track/cylinder is 'lost' but it was lost before we bought the drive because the sectors are 4K so there is nothing 'lost' by the choices we make in fdisk. I must remember to use fdisk -u to see the sector numbers when making the partitions and remember to do some test writes to the partition to ensure it's right and the speed is good before doing any real work. This has been helpful for me. I'm glad Valmor is getting better results also.

[gentoo-user] OT?: Gentoo hosted web services
Hello, Kind of a strange request here. I'm looking for somebody to hire to create a sports (basketball) web site, host it for a few months, until I get my new network ( location) all set up and then transfer the website to my servers. I'll be running apache and both prim/sec DNS servers, eventually. For the right person, you'll most likely be able to 'moonlight' and make moderately complex websites for me and get paid. I'm flexible as to the open source tools you want to use. I have too many things going on, so anyone interested, drop me a line. Beside, I'm not a web centric guy, but, I get asked to create and manage websites all the time, as part of other business. The right person could have a really easy gig and make some money. Most are sports related or for charities. These are not big money website as most I'll host for free, but for the right open-source developer, this is easy money and a very cool and laid back liaison (me). If you have questions post them here, or drop me some private email. (coach) James

I have just checked, and I am getting 3.5 - 6 minutes (real) to untar portage. I had blamed performance of this array on the fact that the RAID controller is an older model PCI card I got cheap(ish) off eBay, but I see it is also aligned beginning at sector 63. I'm not quite sure if this is cause of poor performance here, as the drives in this array are not quite as modern as yours - I'm guessing that at least a couple of the drives have been bought in the last 6 months, but they are only 500GB drives. However I guess it would only require one drive in the array to have 4K sectors and it would cause this kind of slowdown. I will try checking their spec now. This is the same server that caused me to post in relation to slow Samba transfers 3 weeks ago (How to determine if a NIC is playing gigabit?). I have still not yet tested thoroughly - there are always chores getting in the way! - but it seems like I was able to transfer the same files in about a third (or maybe even a quarter) the time at 100mbit, between my laptop desktop Macs. I am not immediately able to alter the partition layout, as I have scads of data on this array. In order to test I think I will need to create a second array, aligned optimally, and copy the data across. I had been recently thinking that 2TB drives are now 40% cheaper per gig than 500GB ones, so perhaps I will have to splash out on 3 of them. This seems rather a lot of money, but I could probably use the space.

Re: [gentoo-user] Sipix Pocket Printer A6
I can get the Sipix Pocket Printer A6 installed in CUPS and it will get about 20% through a CUPS test page, but it always stops in the same spot and the LED just blinks. Does it do the same with standard printing jobs? I ask because I have an Epson printer that failed on the CUPS test page, no matter what I tried, but then I tried printing a photo from KDE and it worked perfectly. It works! The thing just needed new batteries. For anyone else reading this, flashing LED = replace batteries. It has a few problems: 1. The printer doesn't show up in Print dialogs. It shows up in localhost:631 and prints the test page and via lpr. Why wouldn't it show up in the Print dialogs? Is it because it's a serial printer? 2. I'm using a USB-serial converter and I get a permissions error when trying to print unless I chmod /dev/ttyUSB0. The file shows up before chmod as: crw-rw 1 root uucp The problem with chmod is it resets after unplug/plug. My user is in the uucp group. How can I enable printing after unplug/plug without chmod? 3. lpr doesn't work unless I set: # export CUPS_SERVER=localhost which resets after reboot. This wouldn't really be a problem if I could get #1 fixed above because then I could use the Print dialogs instead of lpr. 4. The printer feeds a lot of paper before it starts to print.

Good question. I don't know where it starts counting but 63 seems to be the first one you can use on any blank drive I've looked at so far. There's a few small downsides I've run into with all of this so far: 1) Since we don't use sector 63 it seems that fdisk will still tell you that you can use 63 until you use up all your primary partitions. It used to be easier to put additional partitions on when it gave you the next sector you could use after the one you just added.. Now I'm finding that I need to write things down and figure it out more carefully outside of fdisk. 2) When I do something like +60G fdisk chooses the final sector, but it seems that it doesn't end 1 sector before something divisible by 8, so again, once the new partition is in I need to do more calculations to find where then next one will go. Probably better to decide what you want for an end and make sure that the next sector is divisible by 8. 3) When I put in an extended partition I put the start of it at something divisible by 8. When I went to add a logical partition inside of that I found that there was some strange number of sectors dedicated to the extended partition itself and I had to waste a few more sectors getting the logical partitions divisible by 8. 4) Everything I've done so far leave me with messages about partition 1 not ending on a cylinder boundary. Googling on that one says don't worry about it. I don't know... So, it works - the new partitions are fast but it's a bit of work getting them in place. - Mark

If I'm understanding correctly, then the drive will *always* have to start at the 63rd sector, then swing back round and start reading a 1st sector, for every read larger than 1 byte. This will result in a minimum of one extra rotation of the disk's platter for every read, and instead of reading larger data contiguously the effect will be like a *completely*, least-optimally fragmented filesystem.

Hmm. That gave me the clue; yes, freemind was throwing an ant error

success), so I recompiled all the ant* packages on the system and that's
fixed it.

That's a puzzle, because I'd only just run an emerge --sync and -uaDv

The upgrade of antlr pulled in a new package, stringtemplate.
Whatever was wrong, reinstalling those four packages solved my problem.

It is possible you can use some of those; I never tried. That's a negligible amount of space on modern harddrives anyway. And actually, starting on sector number 63 means that you are skipping 63 sectors, not 62, since LBA numbering starts with 0. Historically there is a reason for all drives coming with default formatting with the first partition at section 63. Sector 0 is the MBR, which you shouldn't overwrite. MSDOS and all Windows up to XP requires the partitions be aligned on Cylinder boundary. So it is safest to just partition the drive, by default, such that the first partition starts at LBA 63, or the 64th sector, or the first sector of the second cylinder. Actually, this is why Western Digital et al are releasing this flood of 4K physical sector discs now. Windows XP has been EOLed and Vista and up supports partitioning not on cylinder boundary. If Windows XP still had support, this order of magnitude inefficiency wouldn't have been overlooked by most consumers. I bought this 500GB drive for my laptop recently and did a fresh partitioning scheme on it, and then rsynced the filesystems of the old, smaller drive onto it. The first two partitions are ntfs, but I believe they also use cluster sizes of 4k by default. So technically I could repartition everything and then restore the contents from my backup drive. Are you sharing the harddrive with a Windows operating system? Especially Windows XP? There are reports that Windows XP supports partitioning not aligned to cylinder boundary. However, if you are dual booting you will almost surely be fscked if you try that. I had some fun earlier last year when I did everything else right but couldn't figure out why my laptop tells me it cannot find the operating system when I tried to dual boot. Though the result justifies your decision, I would have though one has to start at 65, unless the disk starts counting its sectors at 0.

Just find a few that suit your needs most closely and copy them to /etc/ For example, to get a basic working keyboard/mouse combination, you could copy the following files... /usr/.../10-input-policy.fdi /usr/.../10-x11-input.fdi . Am I the only person that finds this semantic gibberish? Is there any explanation somewhere of what a policy aka device rule is? What is the semantic significance of a device rule? What does it mean, to rule a device, or what sort of restrictions are being placed on this device?

[gentoo-user] severe tearing and system lockup
Hi all, I've had this problem with various nvidia-drivers and never been able to track it down. AFAIR it only happens during certain (one?) xscreensaver hack. One of the 3d ones, but not necessarily one named GL* When the hack starts, I see multiple tears every 1-2cm (10-15 in all), each one offset to the right by the same amount. The colours look inverted, or neon. The screen is frozen. I can ssh in and initiate a shutdown, although it doesn't complete; or I can use the magic sysrq key. When the shutdown locks up, I can't use sysrq. Perhaps this is related, but when I run MoebiusGears with the settings maxed I can get performance like this: FPS: 220 Load: 100 Polys: 12000+ but sometimes on a different instance the FPS drops drastically to 90. Don't know why. I have: nVidia Quadro FX 1600M (laptop) 2.6.32-tuxonice-r1 x11-drivers/nvidia-drivers-190.53-r1 x11-wm/compiz-0.8.4 x11-base/xorg-server-1.7.4 any ideas? thanks, -- Iain Buchanan iaindb at netspace dot net dot au Harp not on that string. -- William Shakespeare, Henry VI
