similar to: EVMS?

Hi all Sombedody can points me to a good tutorial about using high availabilty clusters with xen using heratbeat2, ocfs2 and evms under rhel/centos, debian or sles?? I am doing various searches without a result ... (google shows me a lot of references, mailing lists, etc but not a good doc) Many thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

The tools for raidN (mdadm and friends) don't seem to compile with klibc. Has anyone tackled that, lvm or evms yet in a klibc-based initramfs, or do you usually include uclibc or something when it comes time to get fancy (also, looking ahead to crypto-root and such) Tks, Jeff Bailey

Hi, I have seen a few posts on the list from people who were working on this. If anyone has succeeded can you please drop me a line with some notes on your boot process and the initrd creation process please? I seem to have the bits all working individually, but I can''t quite figure out how to get Xen kernel to boot up and start my EVMS stuff under Gentoo. At the moment I have been

I remember seeing one with an example migrating from an old fashioned filesystem on a partition to a new filesystem on a mirrored lvm logical volume but one only one side of the mirror is set up at this time. First I need to copy stuff from what will become the second side of the mirror to filesystem on the first side or the mirror Then I will be ready to follow the rest of the tutorial and

Hi, A problem with EVMS and Xen: I have patched a 2.6 kernel with the evms patches and then with the Xen patched, compiled and installed it. (kernel is 2.6.11.9 - which is what this server has been running for the past few months w/o the evms patches) At first everything seems to work just fine, I am able to use evms to create a new "volume", in this case it is based on MD/RAID-5 but

This sort of message is usually preceded by some magic tones that allow direct marketing application to immediately drop a call to a dead phone number. What is the proper terminology for the tones? Where can I find information about how this is implemented? -- Drew Einhorn

I started with two 160GB drives in RAID1 using EVMS on Centos 4.4. Both drives have now been replaced with 320GB drives but naturally are only offering 160GB (they were replaced individually at different times and self-recovered as they were RAID1. I cannot work out how to increase the size of the array to use all the available space on the disk. If I understand correctly, I should unmount the

To support small biz, family. Have a bunch of old clunker boxes on the scrap heap that would probably do the job as a server. But I'm not confident they would be reliable enough. Capable of supporting maximum of a dozen 2-line ATAs. Don't want to spend more than a couple hundred dollars on a new server box. -- Drew Einhorn -------------- next part -------------- An HTML attachment

There is a setroubleshoot package that runs under X, that really makes it a lot easier to troubleshoot selinux, but I really don't want to run X on all my vms. Does anyone here know of an equivalent that doesn't require X? -- Drew Einhorn -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I'm having a problem with Verizon Wireless, I'm hoping someone here knows the right way to phrase the trouble report so it gets to someone at Verizon who can solve the problem. We have DIDs that simultaneously ring on voip lines, and Cell numbers. Verizon voicemail is turned off. Every thing works the way it's supposed to, UNLESS one of the cellphones is turned off, or in a

Hi, I want to rename some volume groups and logical volumes. I was not surprised when it would not let me rename active volumes. So I booted up the system using the CentOS 5.5 LiveCD, but the LiveCD makes the logical volumes browsable using Nautilus, so they are still active and I can't rename them. Tried: /usr/sbin/lvchange -a n VolGroup00/LogVol00 but it still says: LV

Hi, I''ve been posting this question to lots of lists and not getting good answers. I have a Ubuntu Hardy laptop. With a ssh connection to a RHEL5 xen dom0. Running cobbler/koan on the dom0 Koan --virt --nogfx ... starts a new domU on the xen box and starts up the RHEL5 installer the installer attempts to configure its network interface using DHCP and gets stuck If this was an install

Hi, I'm in the process of trying mdadm for the first time I've been trying stuff out of tutorials, etc. At this point I know how to create stripes, and mirrors.

I'm having a problem with Verizon Wireless. I would be extremely surprised if I was the only one having this problem. It seems to me that Verizon Wireless might be able to use one of the Special Information Tones to allow us to solve the problem. But I really do not whether my suggestion is compliant with the ITU-T standards. Perhaps someone can give me an expert opinion on whether I

I saw something somewhere about AHCI support requiring kernel 2.6.19 or later. But the current CentOS/RHEL stable kernels are 2.6.18 I'm trying to run CentOS/RHEL in a VirtualBox vm, which by default creates sata virtual disks with an AHCI virtual controller. These virtual machines are quite unstable, and I'm wondering if the AHCI virtual controller is the problem. I do have a real

Hi, I'm trying to repair a remote system using the Live CD. I have VPN access to the subnet where it lives. An onsite person is booting from cd, and running a small script I provided to tweak the default firewall rule set to allow incoming ssh, and set a password for the centos user and start sshd so far so good I can remotely access the system. the problem is the live cd environment is

Hi, I've installed Samba a few times, and I always have the same problem - except now I really want to get rid of it. My Samba server is very, very, very slow on occations (not always), and some times it's really annoying. What happens is that it doesn't seem to be online for a period of 5-10 seconds once every minute! If I'm copying huge files, it's working great, but when
