Mark, On Tuesday, July 5, 2011 you wrote: > Has anyone seen a supported hardware list on CentOS 6? Check my question regarding the same question from May. 3rd this year with the subject "list of supported hardware". There is a list of certified hardware, but no list of supported hardware. I find this strange as in my opinion the hardware support is mainly handled in the kernel. If people are writing drivers for the kernel, it would be quite simple to ask them adding the supported hardware to a list. Some two years ago I had an issue with a new motherboard. After a kernel update, it had massive memory errors in the log-files. It turned out that a new kernel driver simply added the feature of reporting errors. They were there before, but not reported. I had to wade through the kernel source code and the history-files to figure out what had happened. Not really good, but OTOH no CENTOS problem. best regards --- Michael Schumacher PAMAS Partikelmess- und Analysesysteme GmbH Dieselstr.10, D-71277 Rutesheim Tel +49-7152-99630 Fax +49-7152-996333 Geschäftsführer: Gerhard Schreck Handelsregister B Stuttgart HRB 252024 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

In general and with some simplifiying assumptions, a database consists of statically pre-allocated files. The process of extending the files happens at birth.

[CentOS] getting old mail every 5 months or so
Using centos 5.x, sendmail, as a server, downloading mail with thunderbird (although this happened with outlook too) every 5 or 6 months I open my mail client (thunderbird) and one of my mail accounts decides to download 1,000 or so mails from my server. Old mail that I had already downloaded before. I changed no settings and everything is the same as it was, but this happens enough, on all accounts, that it is just weird. It is like it gets to a certain size and then redownloads the same mails. And they are the same mails. I have had 'redownloads' of the same emails each time. I look in the queue, nothing there...same with the mailboxes in the user folders, var/spool/mail these mails are being held somewhere by centos, but I cannot find them...and they seem to want to all be downloaded again and again every 6 months.. what am I missing? thanks ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

But it doesn't matter if you lose the read cache in RAM - and the OS is going to keep a copy there as long as it can anyway. The point of SSD caching of journals/writes is that it survives a reboot.

It's in the Centos updates repo. Just try 'yum info wireshark*' Running that will enable you pinpoint what your network problem is.

We (elrepo) certainly aren't prepared to create and redistribute binary "kmod-wl" RPMS given the Broadcom licensing restrictions. However, one of our colleagues recently required these packages so we did knock up some kmod packages for el5 and el6 for our own internal not to be redistributed private use. As there is evidently a high demand for them, we have decided to make available our SRPMS (well, .nosrc.rpm actually) which end users can rebuild themselves. http://elrepo.org/linux/elrepo/el5/SRPMS/wl-kmod-5_100_82_38-1.el5.elrepo.nosrc.rpm http://elrepo.org/linux/elrepo/el6/SRPMS/wl-kmod-5_100_82_38-2.el6.elrepo.nosrc.rpm Because these packages do not contain or redistribute anything from Broadcom they are not subject to Broadcom's licensing, hence we feel we are able to distribute them if they benefit the community. I think we have some detailed directions somewhere on how to build the packages from our SRPMS so perhaps one of my colleagues will get that posted up shortly. Hope that helps. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thanks for the quick reply and explanation. You said use dd kit from rhel and create a linux device driver image and supply drivers during OS installation. dd command i suppose. Please further suggest. I have extracted the rpm file and it has hpahcisr.o file. Am i understanding you correctly ?

I had hoped to avoid merging the CDs into a http-accessible directory and merging the repos, if I can avoid it. I'll be installing as a Xen domU, so having a single ISO also makes it easier to just boot off of the one image, rather than needing to swap out mounted ISOs.

We're going to move away from it to a modern release, but until then, we don't want to risk breaking anything. For this reason, we want to stick to the 4.3 install on the current server. -- Digimer E-Mail: digi...@alteeve.com Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "I feel confined, only free to expand myself within boundaries." ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Playing Descent with those things was a > blast! :) Well, yes, sure, but they have to have this lens to allow the eye to focus properly, as you said. This means two crucial things: (a) they have to be bulky, and (b) there is no way to make them transparent, so that a person can watch the monitor picture and the outside world simultaneously. By (b) I mean having computer graphics overlayed on top of real-world scenery (like in Terminator or Robocop movies). I'm just saying that this kind of overlay is impossible to achieve with a regular human eye, except with very bulky equipment hanging off your head 15 cm in front of your face. Anyway, for both of the above reasons, these AV-headsets don't qualify even as a predecessor of "monitor-shades" (which are by assumption thin and transparent). These things are used for virtual reality applications, and they have existed for some time now. But as long as they cut you off from real world, I cannot consider them as "shades" in any way. ;-) Best, :-) Marko ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

OS X does use TCP but I've just run tcpdump on an F15 VM while mounting and unmounting an NFS share from my Mac. Both the mount and umount result in four UDP packets, two to the portmapper and two to random ports. I don't have time to experiment further right now but perhaps opening up 111 UDP will allow your Macs to mount the NFS shares. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] CentOS on the HP MicroServer
I was looking at the marketing hype on those machines, and they look like they take a standard 3.5" SATA drive. OTOH, some pictures of the HP model drives for the microserver look like there's some type of handle on the front. I'm assuming that this is the "hard disk carrier" mentioned in the installation manual. Does the basic microserver ship with four of those drive carriers, or do they have to be purchased separately? Also, would anyone who has a CentOS-based microserver with a remote access card care to share any observations about that card, such as integration aspects and accessing it in a completely windows-free environment?

Note they are not advertised as hot swap, I believe this is probably because there is no SES (enclosure services) and Windows in particular is not happy about hotswapping disks without one. afaik, if you go to the trouble of using the mdadm commands on linux to take the drive offline before removing it, you should be able to 'warm swap' as there's nothing in the hardware preventing it, and the SATA connector is inherently electrically safe for hotswap. I haven't actually used one but the Remote Access Card provides a web based KVM, and if its anything like iLO Advanced (various websites seem to think its equivalent), it likely uses a Java-in-your-browser based VNC implementation for the remote VGA, so this should be pretty easy to get going with Firefox+Java on a 'nix platform.

When a table or index exceeds 1 GB, it is divided into gigabyte-sized/segments/. The first segment's file name is the same as the filenode; subsequent segments are named filenode.1, filenode.2, etc. This arrangement avoids problems on platforms that have file size limitations. ... Each file is no larger than 1GB (by default), but its written and expanded as needed, not in any fixed size increment. > The "WAL" files you refer to are apparently database > transaction logs.

The wal logs are 16M files, also written sequentially as needed, and nearly continuously on a insert/update intensive database. they are not reused, rather, old wal files are deleted (unless you're archiving), and new ones are created continuously. -- john r pierceN 37, W 122 santa cruz ca mid-left coast ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
