Google-Base is really the only way to get mass-data into Google. Do you think Google spiders ebay? Do you think they are going to spider your "site"?

Re: [CentOS] Stop the FUD Xen is not deprecated
It makes a difference. All of what I hear about KVM clearly states that its performance is much worse than a paravirtualized RHEL/CentOS. i never mentioned anything about performance - pvirt works very well for me right now on a large scale so with 'support' being around for over 6 years i see no reason to try anything else at the moment. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Looking for an application to work with Centos
Frank thank you for the feedback... I understand that there will not be a real time Spidering and update of Google, that's fine, once the 150,000 part numbers are Spidered once, then that is 1/2 the work done. The other side, that I want to be some what real time, is a onsite search feature so that real customers can see true, or close to true information... What some people do, is build a pade with every part number know to man on it, just a basic stream of text on a page, one after an other, after several tens if not hundreds of pages they have the information on the web. In that manner, they then can be Spidered by the search engines. These companies don't have the product, but they do get requests for the product and then they go out into the world to fine it, they are known as brokers. The other side of the coin is what we do, we hold inventory on at least 150,000 different part numbers, in a mix of quantities amounting to millions of pieces of inventory on hand. I have this inventory in a Firebird DB, I'd like to find a way of dumping this information into a program that will create pages on our website, or at least create a catalog on our website that can be spidered by the various search engines. My first thought was a basic Shopping Cart, I use one now on our surplus electronics and consumer website.. Some basic information on the part, entered in plain text, and the cart uses its PHP scripting to generate a page, these pages are captured by the search engine spiders, driving people to our website. It is called SquirrelCart, but it has more bells an whistles than is needed for this project, if a person gets to our site, I just want them to be able to see if we have the item in stock and show them a quantity, if we do, then give them a phone number to yalk with my sales department, or a web form to let them contact us... KISS, I want to keep it simple...

I don't think you're going to get the results that you think you're going to get, assuming that by "search engines" you mean Google, MSN and the like.

[CentOS] Reassemble software RAID
I have a machine on CentOS 5 with two disks in RAID1 using Linux software RAID. /dev/md0 is a small boot partition, /dev/md1 spans the rest of the disk(s). /dev/md1 is managed by LVM and holds the system partition and several other partitions. I had to take out disk sda from the RAID and low level format it with the tool provided by Samsung. Now I put it back and want to reassemble the array. Machine boots fine from sdb and I was able to re-add /dev/sda1 to /dev/md0 easily. However, I can't do the same with /dev/sda2 to /dev/md1 because there's no /dev/md1 anymore and mdadm tells me it doesn't have the RAID superblock. If possible I want to avoid deleting the already existing setup and data. I'm wondering what I shall do next. Can I simply create /dev/md1 as if it was a new array? Is the problem created by the fact that the running system was booted from a logical volume on /dev/sda2? Should I better boot the system from a live CD and then reassemble/create anew /dev/md1? In general, would it be better to *not* put the main system on a logical volume on a RAID partition? (The other logical volumes carry virtual machines.)

Re: [CentOS] [Q] what is difference between CENTOS and ORACLE unbreak Linux
mcclnx mcc wrote: ORACLE unbreak Linux and CENTOS both source code come from Redhat LINUX. Does there have other difference between CENTOS and ORACLE Linux? ok, you seem confused and seem to be buying into the marketing that oracle sends down the line. The 1 major difference is that CentOS really is binary compatible with upstream RedHat. Oracle isnt. They ( oracle ) patch and change gcc / glibc - use a custom kernel, modify configs, remove and add packages to the distro enough that they cant and do not have basic reproduceability that one would inherit into CentOS from Redhat[1]. Also, oracle lacks credible inhouse support. If you really want to get a contract, go with RHEL. or with CentOS and your local vendor. imho the support you get from the local vendor and CentOS is way better than what Oracle are able to offer for a linux OS. Oracle are also not open source friendly - their sources and updates are not publicly listed[2]. Also, dont buy into that 'oracle test a lot more' - they dont. Their packages are inherited from CentOS and they actually rely on the testing that we do with the packages. - KB [1] Oracle Linux on a specific machine was only able to hit 12k emails per minute, whereas on CentOS and RHEL we got 18000 emails per minute.

Fedora10 does have DomU support for Xen, dom0 support wasent ready in time, the timeline does indicate that Fedora11 will bring dom0 support back pending xen on paravirt_ops running production grade. But then once that happens, it does not really matter, since I'd expect most of Xen to get upstreamed into the mainline kernel - making distro support kind of academic. Also, fedora10 contains all of xend and libvirt support, so if anyone wants to bring in a kernel specially built for it, all the userland and setup is already in place.

You don't really need to buy anything, you do if you want fancy enterprise-like management of multiple systems from one screen. And there are limitations in ESXi, it certainly isn't equivalent in abilities to enterprise or standard edition. But as far as using it to virtualize systems it works ok, and you can use Virtual Infrastructure client, the same client you use for their non free versions of ESX(assuming no VirtualCenter of course). VI Client is free. A big downside to ESXi is it does not support serial consoles(yet), and we've had some painful experiences trying to get 802.3ad+802.1q working, while it was painless doing the same in ESX Foundation, not sure what the issue was. I've also read in their features list that ESXi does not support cold migrations, nor snapshots, I haven't tested either of these situations yet myself. These are two key things that I find critical. If your not on shared storage than cold (or hot) migrations isn't an issue. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I noticed the chorus of agreement that your problem was likely a result
of failure to mount your backup drive. My backup script, which also
uses rsync begins like this, insuring a good mount before shoving bytes
around. It's not SUPPOSED to be mounted before the script runs but I
test for that, too. (The drive label is OTOT):
#!/bin/bash
# Backup using rsync and rotating directories
#
#Set the Dest. Mount

Thanks Robert, Ned, William, et al (no offense intended to the many not
named here), who replied with the need for logic and for checking that
all devices, including the ext HDD, were connected to the UPS.
Re: Logic in the script: no doubt, I will be modifying it to check for
valid mount point before starting. As always, I'm learning from my
mistakes :)
As for the server having been up, I think what happened was the server
and the HDD (which was connected to the UPS) went down before the rsync
was scheduled to run. When power was lost, the mount point wasn't
properly released. When it came back up and online, the USB drive was
mounted to /media/bkup_ (trailing _ provided by the system) which turned
out to be a folder on /, not a pointer to the external drive.
Again, thanks for the tips, pointers and sound ideas.

Show us a link where it says Xen was dropped by Fedora.

So very much off topic but I can't resist :) I like vmware a lot because they have made good products and have been a very long time supporter of linux. I have been using vmware since before 1.0 back in 1999 or maybe late 1998 on linux. In 2003-2005 I used a bunch of VMWare GSX(again on linux), worked well, never let me down.

Well put, I also think that too. I think the failure of Xen was it's failure to get included in the Linux kernel early on. Now it's too late, there is such a wide gap between their 2.6.18 kernel and the current 2.6.27 kernel and the work to catch up their hypervisor/kernel to current is going to make the work of polishing their existing code suffer, not to mention that the distributions out there are readying new releases on more current kernels that won't have the Xen api built in and will need to either drop or patch/maintain them which is too much work/effort = $$$. Not getting Xen into the kernel earlier is going to be Xen's downfall. -Ross ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I'd be happy to have you over my place and we can do some real world
performance testing in server roles. I'd also be happy to show you
exactly how mediocre the vmware platform appears to be in some real
world deployments.
vmware have been around for a long time, and they do have a usable
product and it does do loads in different incantations. But one thing
its not good at is SME virtualisation. An area they know well, and
something they are quite concerned about.
btw, as might not be clear to some people, I dont do Windows
hosts/guests so dont know what the issues there might be. My experience
is purely based on Linux centric stuff.

I'm not aware of any method under linux directly to reserve a set amount of CPU resources. You can use /etc/security/limits.conf to restrict certain amounts of resources but there is nothing there even that impacts CPU usage on a percentage basis, and of course nothing that will reserve CPU. If you can't login with root it sounds like the load on your system is likely very high, so I'd reduce the amount of working threads. There's a big difference between cpu usage being at 100% and a low number of things that are contributing to that 100% usage number, and having cpu be at 100% and many things contributing to that number. The latter will definitely have far more serious performance impact than the former in my experience.

Re: [CentOS] Looking for a method to keep at least 5% CPU
I can recall on countless occasions over the years being able to login to a system that is running at 100% cpu usage and not really have any noticeable impact on being able to login or interact with the system. I agree here. I do remember not being able to log in when i/o is completely swamped though. Maybe the problem is not so much 100% cpu usage but disk i/o. The box might be thrashing swap. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Centos 5.2 install problem
Hi, I'm trying a fresh install on a x86_64 (Supermicro X7dbe, 2xIntel Xeon X5450, 8 GB, 3WARE 9650SE-8LPML, 3 disks in RAID 5). The format takes quite long (2,7 TB), that seems to be normal, but then the first boot will not take place, instead the system loops. Any hints? The message follows: Regards Michael Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! -- Michael Kress, [EMAIL PROTECTED] http://www.michael-kress.de / http://kress.net P E N G U I N S A R E C O O L ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Once you install ESXi the VI-client is downloadable directly from that host; just point your browser at the VMware host. Well, but why do you assume people run Windows where you run your browser? You need a Windows license to run VIC, so the price of installing ESXi/VIC is around $100 and up. -- //Morten Torstensen //Email: [EMAIL PROTECTED] //IM: [EMAIL PROTECTED] I can't listen to that much Wagner.

I remember that my server had same problem with over 2TB logical volumes. Installation successfully is point, but can not boot it. Maybe old 3ware driver can't treat over 2TB volumes. go with nate's talk. tonoki ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Any hints? Try again using a volume that is less than 2TB in size and see if it makes a difference? nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
