[CentOS-virt] xm attach-block reboots entire server
I'm still trying to get xen working before Centos 6 and KVM just for experience. I seem to be able to do most of what I what with VMs, but I've run into another problem with CD/DVDs. I can get a DVD mounted on the host domain just fine, but when I try and attach-block to a running guest VM, the entire server reboots. I've tried many different commands versions based on what Google finds, but I'm not getting anywhere. I end up using scp to copy the data from the host to the guest. The guest is basically defined as a full virtualized domain. I'm using /dev/scd0 as the device (it's listed on the mount command) as both frontend and backend devices. And I've tried a few other devices as well, but the same result. Anyone know of a reason or fix, please? steve campbell ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

Since the delta isos going from the DVD to the CDs are of negligible size (for example see the 13-Final/ and 14-Final/ subdirectories of http://alt.fedoraproject.org/pub/alt/stage/deltaisos/ ), it would probably be better to do it the other way around (DVD + DVD-CD disos).

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 ? Hi Kaushal, Maybe there's some kind of misunderstanding. The term software raid can be misleading because IMHO mdraid is also an software raid. So let's use the term fakeraid for those controllers which make one believe they do everything in their hardware but in fact simply do some kind of software raid in thier proprietary OS driver. So, what you should try to find out is whether your controller is not usable in raid mode because the OS has no support for it (seems obvious) or if you set the controller into AHCI mode in BIOS, if the controller is usable by the OS without any additional driver. So, go to the BIOS and set the disk controller to AHCI mode (if such setting exists) and try to install the OS. If you'll see any disks in this configuration, the just go with mdraid and you're done.

How about a glass with lenses that are formed by nano beam splitter/mirrors with projection units on the side where the legs of the glasses would be. Thus transferring the bulk from the front to the sides which would be more wearable than a heavy weight hanging off the nose.

Re: [CentOS] CentOS 6 Progress as per qaweb
Not much of a difference this time, still good for download in 4~5 days. This time it looks more like adjusting based on known time needed to push to external servers. Although I'm quite curious, how is the push done? Given the requirements of 25Mbits for donated servers, it would take less than an hour to push through even 10GB worth of DVD + CDs. It seems quite odd that it takes 2~3 days just to push to internal mirrors. Any public mirrors have this yet? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Devin Reade wrote: 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. I think your questions have all been answered, but I thought I'd add my two cents that I've been really impressed with this box as a home-server. (I have two, in different locations.) There is no handle on the front of mine. There is a key to lock the front panel, which it is important not to lose! Also when you open the front panel, there is a handle to pull out the motherboard. Maybe that is what you saw. I found it quite awkward to pull out the motherboard, which you have to do to add memory or any card (but not to add another SATA driver), but I am no hardware guru, and usually find this sort of thing hard. I saw a couple of YouTube videos, where a guy disconnected the connectors and pulled out the board in about 10 seconds, but I found each of the 6 connectors quite hard to undo. I'm surprised how few people seem to be using CentOS (or RHEL) on this machine, according to the forums I've looked at, as the only 2 OS's supported are RHEL (5 and 6) and Windows Home Server. There is a large amount of software support (eg HP Smart Update Manager) which seems to be RHEL-oriented (there are some RPMs included). Most of the discussions on the forums are about adding as many hard disks as possible (you can put some in the top, intended for a DVD drive). I didn't really understand the purpose of this exercise, as if I wanted a box with 8 drives I wouldn't choose the MicroServer to start with. Incidentally, HP's cash-back offer has been extended for another month, I think, so the box is still absurdly cheap, at about 150 euro. It's been extended about 4 times.

Could it be that even when I am trying to mount over the TCP the NFS client on the Mac OS X side still tried to connect to some UDP port? I am asking that because everyone else mounts just fine with the firewall up on the server end. As I recall OS X only does NFS via TCP - other clients can use UDP - make sure your CentOS firewall has the TCP ports open. 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. NFSv3 uses the nfs port (TCP or UDP), portmapper (UDP) and some random UDP ports for quota, lockd, mount, and statd. These random ports can be fixed by setting them in /etc/sysconfig/nfs. They are normally commented out, but uncommenting them (and setting them to different values if so required) will fix them so you can firewall them.

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. NFSv3 uses the nfs port (TCP or UDP), portmapper (UDP) and some random UDP ports for quota, lockd, mount, and statd. These random ports can be fixed by setting them in /etc/sysconfig/nfs. They are normally commented out, but uncommenting them (and setting them to different values if so required) will fix them so you can firewall them. Thanks doe the reminder! :) My mind's been corrupted by recent Linux releases; I assumed that OS X defaulted to nfsv4 and tcp and my mind didn't connect the random ports with the pre-nfsv4 nfs elements (probably also because I always make them static!). It does default to tcp but doesn't default to nfsv4. Specifying -o tcp produces the udp packets as not specifying -o tcp so OS X's trying tcp and then falls back to udp. Specifying -o vers=4.0alpha produces no udp packets. Perhaps the version of OS X being released this summer'll have a non-alpha nfsv4 mount_nfs... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Bind97
I notice that CentOS 5.6 release notes say that bind97 is now included. However, my CentOS 5.6 installations have bind 9.3. I'm guessing that bind97 is not installed by default, due to the possibility of config file breakage or something. It looks like you have to explicitly install the bind97* packages. I don't see anything in the release notes about how to handle the transition from bind 9.3 to bind 9.7. Has anyone done this, or seen a list of potential pitfalls?

While not CentOS-specific, this *is* in my area of expertise. We have 540Ah of -48VDC driven by a pair of Lorain Flotrol 200A rectifiers for our telco equipment (including the Cisco 12008 and OSR7609 routers). Our solar sites are mostly 24VDC with, again, 540Ah minimum at each site, with a few 12VDC systems with 75 to 300Ah at each site. I've run enough 4/0 and larger flex cables, that's for sure. for 41 amps, up to 25 feet or so, relatively small 8AWG is sufficient. That's smaller gauge than the 6AWG and 4AWG I ran for the 12008 and 7609, respectively, for -48VDC power. (I say relatively small; the largest conductor size we have here is 6kA rated busbar, so even 2AWG or 2/0 AWG is relatively small..:-) ) I've seen much larger, specifically in the Brookhaven 5ESS in Atlanta. I remember seeing one branch circuit idling at ~2.5kA. Hmmm, speaking of 5ESS, I wonder what the chance of a CentOS for a 3B15 or 3B20 would be? :-) (No, Russ, before you ask: I don't still have the 3B15's that used to be here.) For a reference on DC power design, useful if you need to support CentOS servers with DC supplies in a telco environment, please see DC Power System Design for Telecommunications by Whitham D. Reeve for the 'canonical' reference work. Everything you need, including current limit and overcurrent protection, low-voltage cutouts, distribution design, voltage drop and wire sizing calculations, and ampacity tables for DC (NEC includes AC ampacity tables, but not DC). And I have a few CentOS boxes running on DC power. And, of course, having powertop running on CentOS, and having some low-power modes, helps tremendously. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Cluster Failover Troubleshooting (luci and ricci)
Ljubomir Ljubojevic wrote: I never installed or used any Conga/lucci/ricci sistem. But as far as I know and understand, you need to have a way for server failing to warn the rest of the nodes. Your log said it failed. Some of the failover sistems need separate network connected to collective file systems. So when eth0 is not working, main node will use eth1(2,3,4) to report this event to all other nodes. What comes to mind is that IP's set for interconnection (in lucci conf) must not be public IP's but of that separate/secundary network in order for main node to be able to contact the rest of the nodes. I hope this helps. Ljubomir Ljubomir, Thank you for your reply. I do have a secondary NIC providing the communication between the cluster nodes. I set this up by creating host entries in the /etc/hosts file and pointing those entries to the IP addresses assigned to the NIC's connected via x-over cable. I then created the cluster using the names specified in the hosts file. I've done some network sniffing on the NIC's connected with x-over cable and there's clearly a constant communication between the two boxes. This leads me to conclude that the cluster communication is both working and moving over the channel I intended. Thanks for the input. Let me know if you have any other suggestions.

Please further suggest. I have extracted the rpm file and it has hpahcisr.o file. Am i understanding you correctly ? Hi Kaushal, Maybe there's some kind of misunderstanding. The term software raid can be misleading because IMHO mdraid is also an software raid. So let's use the term fakeraid for those controllers which make one believe they do everything in their hardware but in fact simply do some kind of software raid in thier proprietary OS driver. So, what you should try to find out is whether your controller is not usable in raid mode because the OS has no support for it (seems obvious) or if you set the controller into AHCI mode in BIOS, if the controller is usable by the OS without any additional driver. So, go to the BIOS and set the disk controller to AHCI mode (if such setting exists) and try to install the OS. If you'll see any disks in this configuration, the just go with mdraid and you're done. Simon Hi Simon, Thanks for the explanation. Please help me understand why do Hardware Vendors provide onboard storage raid controller chipset on the motherboard (fakeraid if its a software raid.).

That said, many onboard RAID chipsets work fine with various Linux distributions, and all of them work fine with Windows. In the case of Windows you also need to install the drivers while installing Windows. And this is cause the OS developers, whether Linux, UNIX or Windows don't always have the drivers readily available to include in the installation files but instead rely on the hardware developers to supply the drivers on disk, or on the internet. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

As per http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-swapspace.html It says it should be 1 x of Physical RAM or less. Not sure about the less word in deciding swap space size IIRC, the traditional rationale behind having at least as much swap space as physical memory has to do with being able to save a core file (on reboot) if the kernel bites it. Different UNIX variants had slightly different concerns and values (in some cases 2x physical memory). Other things that can influence wanting a lot of swap are: - if you need to support hibernation - if you're using kexec (I think) - if you're using tmpfs filesystems to any degree - if you're using a serious amount of buffer cache (such as on a file server) In all of those cases, swap will generally be used in a sensible fashion; you may use a lot, but that doesn't imply thrashing. Without those circumstances, you still want a reasonable amount, but I'd be less concerned with matching the amount of physical RAM. The rule of thumb I use to start on CentOS systems is a minimum of 2G total or 1G per core, whichever is greater. Despite that, if your swap in/out parameters are consistently non-zero, you're best to solve it with RAM. If you put your swap on an LVM volume, you can always easily tune it up and down as your needs change.
