Re: [CentOS-docs] Automated listing of translations on each wiki page
Dear all, On 10/13/2010 01:57 PM, Timothy Lee wrote: This is a continuation of the discussion on Link to Chinese translation in Wiki frontpage dated 7 May 2009. To re-cap, I have suggested that the patch in http://moinmo.in/FeatureRequests/ThisPageInOtherLanguages can be used to automatically generate links to translated pages at bottom right of the wiki panel. In addition, I have proposed that the use of a dictionary to look for translated page names should be dropped from the patch, since our wiki strictly uses locale prefixes to label translated pages. To that end, I have cooked up the proposed patch targeted for MoinMoin 1.5.9 (available in CentOS 5.5). I have uploaded the patch to http://moinmo.in/FeatureRequests/ThisPageInOtherLanguages?action=AttachFiledo=viewtarget=simpler.patch . It is also attached here. I sincerely hope that the patch can be applied to the official CentOS wiki, thereby making all translated pages a lot more more accessible to the public.

Thanks for that link. Just to make my criticism of the initial claim more clear: I don't claim that HVM can never be faster than PV but that you need to understand when exactly this is the case.

GPLv3 has a similar requirement, stating that an offer must be valid for “anyone who possesses the object code”. These requirements indicated in v2 § 3(c) and v3 § 6(c) are so that non-commercial redistributors may pass these offers along with their distributions. Therefore, the offers must be valid not only to your customers, but also to anyone who received a copy of the binaries from them. Many distributors overlook this requirement and assume that they are only required to fulfill a request from their direct customers.

Most code is still under v2. Also, there are legalise around exactly what is considered a product / code snippet / build script and distribution - which is what makes things like NDA's workable. Actually, the GPL forbids using 'add on' agreements like NDAs that attempt to make it so an end user can't recompile or redistribute the code. The authors thought of those attempts to 'end run' the GPL's obligations when they wrote it. That is why clause 4 of the v2 license (or clauses 8 and 10 of the v3 license) exists. *v2: 4.* You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. NDAs that attempt to impose *restrictions* on the GPL while still publishing/distributing to a third party can't overcome the basic legal obligations of the GPL and this is *by design*. And yes, code snippets and build scripts are covered, too. See clause 3 of the v2 license. Being as deeply involved in a FOSS exercise like CentOS as you are, you really should take the time to fully understand the license that enables it to happen at all. -- Benjamin Franz ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

GPLv3 has a similar requirement, stating that an offer must be valid for “anyone who possesses the object code”. These requirements indicated in v2 § 3(c) and v3 § 6(c) are so that non-commercial redistributors may pass these offers along with their distributions. Therefore, the offers must be valid not only to your customers, but also to anyone who received a copy of the binaries from them. Many distributors overlook this requirement and assume that they are only required to fulfill a request from their direct customers. Once you publish/distribute GPL licensed code to *anyone*, your obligation to provide source kicks in for *everyone*. In practice, few people hammer at a company in process over it. But you *can*. I'm fairly sure the FSF has never taken the approach of forcing anyone to distribute source to anyone who did not have binaries and thus the offer to receive source. In theory you can't restrict the people who receive either binaries or source from redistributing them, but with RedHat you lose your service subscription if you do, and since non GPL'd parts are included, you'd have to separate them (kind of the point of using CentOS...). -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Most code is still under v2. V3 just makes it explicit. v2 wasn't intended to force anyone to distribute source to anyone who didn't have binaries, and if it did, it certainly couldn't dictate terms (i.e. you could charge any price you wanted for it). Also, there are legalise around exactly what is considered a product / code snippet / build script and distribution - which is what makes things like NDA's workable. Actually, the GPL forbids using 'add on' agreements like NDAs that attempt to make it so an end user can't recompile or redistribute the code. The authors thought of those attempts to 'end run' the GPL's obligations when they wrote it. That is why clause 4 of the v2 license (or clauses 8 and 10 of the v3 license) exists. *v2: 4.* You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. NDAs that attempt to impose *restrictions* on the GPL while still publishing/distributing to a third party can't overcome the basic legal obligations of the GPL and this is *by design*. And yes, code snippets and build scripts are covered, too. See clause 3 of the v2 license. Being as deeply involved in a FOSS exercise like CentOS as you are, you really should take the time to fully understand the license that enables it to happen at all. There are many different licenses covering code in Linux and *bsd distributions. It doesn't make sense to consider one of them any more important than the others.

Re: [CentOS] more software raid questions
Nataraj wrote: I've seen this kind of thing happen when the autodetection stuff misbehaves. I'm not sure why it does this or how to prevent it. Anyway, to recover, I would use something like: mdadm --stop /dev/md125 mdadm --stop /dev/md126 If for some reason the above commands fail, check and make sure it has not automounted the file systems from md125 and md126. Hopefully this won't happen. Then use: mdadm /dev/md0 -a /dev/sdXX To add back the drive which belongs in md0, and similar for md1. In general, it won't let you add the wrong drive, but if you want to check use: mdadm --examine /dev/sda1 | grep UUID and so forth for all your drives and find the ones with the same UUID. When I create my Raid arrays, I always use the option --bitmap=internal. With this option set, a bitmap is used to keep track of which pages on the drive are out of date and then you only resync pages which need updating instead of recopying the whole drive when this happens. In the past I once added a bitmap to an existing raid1 array using something like this. This may not be the exact command, but I know it can be done: mdadm /dev/mdN --bitmap=internal Adding the bitmap is very worthwhile and saves time and risk of data loss by not having to recopy the whole partition. Nataraj ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos mdadm /dev/mdN --assemble --force could also be useful, though I would be careful here. To use this, you would have to stop all of the arrays and then reassemble. You could also specify the specific drives. If you don't have a backup, you might want to backup the single drives that are properly mounted from md0 and md1. Data loss is always a possibility with these type of manipulations, though I have successfully recovered from things like this without losing any data. In fact I pull drives out of a raid array and add new drives in daily to sync them and send the second drive off site as a backup.

[CentOS] Increased memory usage between 4.8 and 5.5
I'm running into a memory problem when trying to switch some web servers that are running centos4.8/x86_64 to centos5.5/x86_64. The new servers running centos5.5 are using a decent amount more memory than the centos4.8 servers. Here's an example from top: --- centos 5.5 --- $ uname -a Linux ws51 2.6.18-194.17.1.el5 #1 SMP Wed Sep 29 12:50:31 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 7799 nobody16 0 348m 101m 43m S 0.0 2.6 1:10.91 httpd 20285 nobody15 0 340m 94m 43m S 0.0 2.4 1:11.36 httpd 31734 nobody15 0 340m 91m 41m S 0.0 2.3 1:13.52 httpd 8904 nobody15 0 341m 89m 39m S 0.0 2.3 0:35.28 httpd 7353 nobody15 0 336m 87m 42m S 0.0 2.2 1:21.17 httpd 26097 nobody15 0 333m 87m 43m S 0.0 2.2 1:28.84 httpd 20765 nobody15 0 335m 86m 42m S 0.0 2.2 0:48.50 httpd 23299 nobody15 0 334m 86m 42m S 0.0 2.2 1:13.35 httpd --- centos 4.8 --- $ uname -a Linux ws89 2.6.9-89.0.28.ELsmp #1 SMP Fri Aug 20 16:11:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 25117 nobody16 0 244m 57m 41m S 0.0 1.5 0:58.23 httpd 21318 nobody15 0 240m 53m 41m S 0.0 1.3 0:53.25 httpd 18517 nobody16 0 239m 51m 41m S 0.0 1.3 0:41.97 httpd 10383 nobody15 0 238m 50m 40m S 0.0 1.3 0:31.07 httpd 29560 nobody16 0 239m 49m 39m S 0.0 1.3 0:40.39 httpd 32459 nobody16 0 238m 49m 40m S 0.0 1.3 0:23.07 httpd 8441 nobody15 0 238m 48m 39m S 0.0 1.2 0:22.87 httpd 1350 nobody15 0 238m 48m 39m S 0.0 1.2 0:29.83 httpd The versions of both apache and php I have installed are the same between the two releases, so I can't imagine that being the problem. I've also tested newer versions and it doesn't seem to make a difference. I've looked into this quite a bit and below is what I've figured out so far. Looking at the output of running 'pmap -x pid' shows most of the libraries in 5.5 are using 2044K or 2048K of memory, but in 4.8 they're all using 1024K or less. Example: --- centos 5.5 --- 2b37c3248000 16 16 0 r-x-- libnss_dns-2.5.so 2b37c324c0002044 0 0 - libnss_dns-2.5.so 2b37c344b000 4 4 4 r libnss_dns-2.5.so 2b37c344c000 4 4 4 rw--- libnss_dns-2.5.so --- centos 4.8 --- 002aa4a5e000 16 - - - r-x-- libnss_dns-2.3.4.so 002aa4a620001020 - - - - libnss_dns-2.3.4.so 002aa4b61000 4 - - - r libnss_dns-2.3.4.so 002aa4b62000 4 - - - rw--- libnss_dns-2.3.4.so This seems to be explained by an increase in ELF_MAXPAGESIZE between the two releases according to this page: http://www.greenend.org.uk/rjk/2009/dataseg.html Another oddity I found that was only in centos 5.5 was a lot of heap memory being marked as Private_Dirty according to /proc/pid/smaps: 2b37c9826000-2b37cc4ca000 rw-p 2b37c9826000 00:00 0 [heap] Size: 45712 kB Rss: 45424 kB Shared_Clean: 0 kB Shared_Dirty: 1580 kB Private_Clean:0 kB Private_Dirty:43844 kB Swap: 0 kB Pss: 43913 kB The highest amount of Private_Dirty showing up on 4.8 is just 1628 kB. Does anyone have any ideas on why 5.5 is using so much memory per httpd process than it does in 4.8? I have 100+ machines I want to upgrade, but that'll have to wait until I figure out why apache uses so much more memory in 5.5...
