Re: [CentOS-virt] KVM virtual machine and SAN storage with FC
Hi Brett, On my plan is as follows: I have two machine (Server) that will host two VM each. One for database and one for application. Then the two machine will provide (Load Balance and High availability). My intention is that all application files and data file for the database should reside on the SAN storage for easy access and update. Therefore the storage should be accessible to both VMs through mounting the SAN storage to the VMs. The connection between SAN storage and the servers is through Fiber Channel. I have seen somewhere talking about DM-Multipath but i dont know if this can help or the use of VT-d if can help. I will also appreciate if you provide some links to give me insight of how to do this. If you need more information, please let me know.

Please let me know the step to go through this. How you use this storage depends on whether you plan to do migration from one server to another. If you're not going to be migrating then you can just allocate the FC LUN to LVM volume group and carve off logical volumes for the KVM VMs to use. These can then have meaningful LVM names in /dev/vg_(VG)/lv_(LV) that can be allocated to the VM. See system-config-lvm. If you're planning to migrate between machines then the LVM solution is not going to work. In that case then you might need to create volumes on you FC controller that will be seen as individual devices/luns on the host servers. There is a consistent device name that can be used that appears under /dev/disk/by-id. This will be identical on any host servers that can see that volume. This can be allocated to the VM and will be consistent for a migration. Using this method requires careful management and meticulous documentation of which LUNs have been allocated to which VM. The lun ids are not very user friendly. We've also have good results with DRBD for times when you want to be able to migrate between machines but do not have a SAN. You have to allocate all the storage on each server but you gain by having a sort of backup. Finally, I can recommend convirt as a good system manager interface.

The switch reports that it is sending a fair amount of traffic to the mirror port. However, within Centos 6.4, I only see broadcast traffic from the switch: This turned out, not to be a problem with Centos, but a limitation or the interpretation of the port mirror feature on the Nortel 3510-24T switch. Setting up a mirror port to capture traffic to/from portx and to/from porty doesn't create a mirror port of traffic passing through either interface, but seems to mirror traffic that passes through both interfaces, which is no good in a VRRP situation!! -- Regards, Giles Coochey, CCNP, CCNA, CCNAS NetSecSpec Ltd +44 (0) 7983 877438 http://www.coochey.net http://www.netsecspec.co.uk gi...@coochey.net ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I'm not sure if it'll help or make things worse, but inline below is a perl script I created to make nagios configuration a bit easier for me. $LOCATION is a directory you've created and added a line for in nagios.cfg, something like 'cfg_dir=/etc/nagios/auto', then feed in data files that look like: #hostname,ip:host-type srv-type :ht:ssh:hts:tcp:tcps:crit,warn router:linux-server:generic-service:0:0:0:80,443:0 nemesis,1.2.3.4:linux-server:generic-service:0:22:0:3128:0:95,98 -i /dev/sr0 spawn:linux-server:generic-service:80:22:0:53:0:85,95 dengar:linux-server:generic-service:80,8080:0:0:0:0:0 so for the 'nemesis' line, it creates a config for host nemesis, doesn't use DNS, but sets the ip to 1.2.3.4, sets it as a generic linux server, all services as generic, doesn't monitor http (ht set to zero means no monitor), checks ssh on port 22, no https check, does a generic tcp connection check for squid (3128), no ssl tcp checks, and then my own custom file system monitor for space that probably everyone other than me should ignore. so if you save this file as hosts.example, save the perl script below as 'parse' and run 'perl parse hosts.example' it'd create a nagios host group called 'example' with all these hosts grouped together and their various ports/services setup to be monitored. I'm sure there are tons of potential pitfalls, and this script should be considered beta at best, but I thought it was useful to me, so maybe it could be for someone else. oh, and the , configs. dengar is a good example it's monitoring http connections on both port 80 and 8080 and as a final note, the standard disclaimer should be understood; I offer this code with no sort of warranty whatsoever. -- ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Weird Okular/KDE error - thousand procs spawned
Hello all: I'm trying to troubleshoot a strange and repeatable error and not sure where to log the bug report. I subscribe to Linux Journal and download their PDF. The DLJ230.pdf opens in the Okular PDF reader from Konqueror. If I scroll down to the ad for some colo site (www.ovh.com) and click the right side of the page, I immediately start getting hundreds of alerts on the desktop. These all say: www.ovh.com contacted. Waiting for reply... Source: http://www.ovh.com/us/index.html They appear at the rate of about one per second. A ps -ef shows hundreds of new processes such as: kwan 27155 24731 0 18:21 ?00:00:00 kdeinit4: kio_http [kdeinit] http local:/tmp/ksocket-kwan/klauncherT24732.s kwan 27169 24731 1 18:21 ?00:00:00 kdeinit4: kio_http [kdeinit] http local:/tmp/ksocket-kwan/klauncherT24732.s kwan 27177 24731 1 18:21 ?00:00:00 kdeinit4: kio_http [kdeinit] http local:/tmp/ksocket-kwan/klauncherT24732.s kwan 27184 24731 1 18:22 ?00:00:00 kdeinit4: kio_http [kdeinit] http local:/tmp/ksocket-kwan/klauncherT24732. I let it run for a few minutes to see if it would time out but it just keeps growing until I finally kill all the kio_http procs (killall kio_http). It's reproducible on at least two CentOS 6.4 builds. Not sure if it's an Okular bug or something else. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] trouble with crash utility
Hi all, I recently had an issue where, running kernel 2.6.32-358.11.1, the box would be up for about five minutes, then would crash and reboot. kdump saved the vmcore files, so I was hoping to run crash against them to see why this was occurring. I copied the vmcores to another machine, installed the kernel-debuginfo package, and gave it a try, but had no success: $ crash /usr/lib/debug/lib/modules/2.6.32-358.11.1.el6.centos.plus.x86_64/vmlinux vmcore crash 6.1.0-1.el6 Copyright (C) 2002-2012 Red Hat, Inc.

[CentOS] Best practices to setup XEN running on CentOS 6.4
Hi everyone, I'm looking for advice on the best way to setup the guest disks on a single-server XEN system running on a Centos 6.4 fresh minimal install as the dom0. I currently have a system running a traditional VHD disk image for each guest but I'm having disk I/O difficulties and I am looking to optimize it the best way I can. The host disks are two classic 500GB SATA-III drives running in software RAID. My question is what is the best way to set this type of system up? Using the VHD disks or a dedicated LVM partition? Ideally the host will run a few VM's, development, MySQL/Memcached, and Web Server utilities. My current planned disk layout is to have a host system running a raid'd root 20GB partition, leaving the rest for VM's. Should the remaining block be a complete LVM device and carve that up for VM's, or is there a better accepted practice for a setup like this? Thanks ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Centos 6.4 and Virtualbox
I'm trying to install Centos 6.4 under Virtualbox on a Mac running Lion. I downloaded the 2 iso DVD files and set Virtualbox to boot from DVD 1 When I start the vm it puts out a lot of messages then asks me what kind of install I want to do. I select the basic install and it tells me it found the media ( the iso DVD file I downloaded) puts out a message about the anaconda ( I think) install starting then goes to a screen with the Centos 6 logo and appears to do nothing. No more messages appear. Should I be using the minimal iso install file? I have installed Windows XP, 7 and 8 under Virtualbox and they all work. I also installed Ubuntu but didn't like it so I removed it and thought I would try Centos Does anyone know what might be going on and how to get it working?

[CentOS] odd inconsistency with nfs
I'm having an interesting/odd problem with nfs (I think). We recently (Monday/Tuesday) upgraded our file server from an ancient redhat 7.3 system to a shiny new centos 6.4 system. We don't see any issues between the other centos boxes, but things get a bit weird when we start mounting on the old solaris clients. The initial symptom was that the 'tab complete' wasn't working, and then we noticed that typing 'ls *' in the mounted directory was bombing. I tried forcing the mounting back to nfs3 but it's not consistent. I've set up two boxes as servers and one of the solaris boxes is my client. Each server has two shares that are mounted on the client. Of those four, one of them works properly and the other three do not. I've spent most of the day trying to debug this and I cannot for the life of me tell why one share works and the rest don't. Nothing seems to be special about that share versus the rest. Here are notes on how things are set up. on duke: (nis server) vi /etc/ypfiles/automap scrs1_bolt-soft,intr,retrans=1 boltzmann:/scrs1_bolt summit_bolt -soft,intr,retrans=1 boltzmann:/summit_bolt scrs1.mirror -soft,intr,retrans=1 goblin:/scrs1.mirror summit.mirror -soft,intr,retrans=1 goblin:/summit.mirror ( cd /var/yp ; make ) on boltzmann: (nfs server) df -h FilesystemSize Used Avail Use% Mounted on /dev/sdb2 50G 13G 37G 26% / tmpfs 3.9G 1.2M 3.9G 1% /dev/shm /dev/sdb3 177G 188M 175G 1% /aux /dev/sda3 208G 44G 164G 21% /aux2 mkdir /aux/scrs1_bolt mkdir /aux2/summit_bolt ln -s /aux/scrs1_bolt /scrs1_bolt ln -s /aux2/summit_bolt /summit_bolt chmod 777 /aux/scrs1_bolt /aux2/summit_bolt service nfs restart vi /etc/exports /scrs1_bolt xxx.xxx.xxx.0/24(rw,no_root_squash,sync,insecure) /summit_bolt xxx.xxx.xxx.0/24(rw,no_root_squash,sync,insecure) exportfs -rv on bigdog: (client) mkdir /tmp/test/b1 /tmp/test/b2 /tmp/test/g1 /tmp/test/g2 touch /tmp/test/b1/nothing_is_mounted /tmp/test/b2/nothing_is_mounted /tmp/test/g1/nothing_is_mounted /tmp/test/g2/nothing_is_mounted mount -F nfs -o nfsvers=3 boltzmann:/summit_bolt /tmp/test/b1 mount -F nfs -o nfsvers=3 boltzmann:/scrs1_bolt /tmp/test/b2 mount -F nfs -o nfsvers=3 goblin:/summit.mirror /tmp/test/g1 mount -F nfs -o nfsvers=3 goblin:/scrs1.mirror /tmp/test/g2 ls -l /tmp/test/* -rw-r--r-- 1 root other 0 Jul 3 14:39 /tmp/test/nothing_is_mounted /tmp/test/b1: total 24 -rw-r--r-- 1 root other 0 Jul 3 12:32 SUMMIT_BOLT -rw-r--r-- 1 root other 0 Jul 3 09:26 boltzmann_test_summit /tmp/test/b2: total 32 -rw-r--r-- 1 root other 0 Jul 3 12:31 SCRS1_BOLT -rw-r--r-- 1 root other 0 Jul 3 09:26 boltzmann_test_scrs1 /tmp/test/g1: total 280 -rw-r--r-- 1 root other 0 Jul 3 15:40 .00_summit_nas_volume -rw-rw-r-- 1 root other 0 Jul 3 15:03 SUMMIT_MIRROR /tmp/test/g2: total 120 -rw-r--r-- 1 root other 0 Jul 3 15:40 .00_scrs1_nas_volume -rw-rw-r-- 1 root other 0 Jul 3 15:02 SCRS1_MIRROR ls -la /tmp/test/b1/* -rw-r--r-- 1 root other 0 Jul 3 12:32 /tmp/test/b1/SUMMIT_BOLT -rw-r--r-- 1 root other 0 Jul 3 09:26 /tmp/test/b1/boltzmann_test_summit ls -l /tmp/test/b2/* ls: No match. ls -l /tmp/test/g1/* ls: No match. ls -l /tmp/test/g2/* ls: No match. mount /tmp/test/b1 on boltzmann:/summit_bolt read/write/remote on Wed Jul 3 15:41:11 2013 /tmp/test/b2 on boltzmann:/scrs1_bolt read/write/remote on Wed Jul 3 15:41:11 2013 /tmp/test/g1 on goblin:/summit.mirror read/write/remote on Wed Jul 3 15:41:11 2013 /tmp/test/g2 on goblin:/scrs1.mirror read/write/remote on Wed Jul 3 15:41:11 2013 umount -a /tmp/test/b1 /tmp/test/b2 /tmp/test/g1 /tmp/test/g2 If I use automount to access the shares on the client, the mounts are made by default with nfs4 and we see this same 'no match' behaviour.
