update from 4.4 to 4.9

I am trying to update i386/686 4.4 to 4.9 I found this: In /etc/yum.repos.d/CentOS-Base.repo, comment out the mirrorlist directives and replace with: baseurl=http://vault.centos.org/4.9/os/$basearch Which I did.

Strange alterations to vim and related packages on KVM host
by James B. Byrne 04 Jul '12

04 Jul '12

OS CentOS-6.2 with updates to present. I use git on this host to manage configuration changes and to monitor package alterations. This is not meant to be a security check. It is simply a way for me to easily recover from fumble fingered configuration changes. Yesterday git status reported that the following files had changed since the previous commit: # modified: ../usr/bin/gdb # modified: ../usr/bin/gvim # modified: ../usr/bin/vim I therefore reinstalled these three packages using yum reinstall and committed the change to git. commit b87a8b2116ef22cc013fd5dc6f525d672d52570a Author: sysadmin.root.vhost01.hamilton <sysadmin.root.vhost01.hamilton@harte-lyn Date: Tue Jul 3 16:22:34 2012 -0400 Reinstalled gdb, vim and vim-X11 due to unexpected changes in executable files. This morning git reports the same three files have again changed. # On branch master # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: ../etc/virsh.run # modified: .Xauthority # modified: .bash_history # modified: ../selinux/policy # modified: ../usr/bin/gdb # modified: ../usr/bin/gvim # modified: ../usr/bin/vim # # Untracked files: # (use "git add <file>..." to include in what will be committed) # # ../.readahead_collect When I check the differences git simply reports that the binary files are difference but, after I reinstalled them all yesterday I noted that the file modification times of the replaced files and their respective reinstalled files were the same but their file sizes were not. Given what I have committed to the git repository I am satisfied that these are the only system files that have changed. None of the files in /var/log show any entries relating to these files immediately prior to the reinstall yesterday. What entries do exist go back to when the software was first installed and none are more recent than several months ago. The git commit on this host previous to yesterday was the Kernel update on June 19. At that time the subject files were the same as when they were originally installed. This host does not accept any direct IP connections from IP addresses outside our internal server subnet (a.b.c.0/192). Access is blocked via IPTables at the gateway and again on the host itself. Some VM guests do allow public or otherwise less restricted access but the VM host itself does not. I am of course deeply suspicious of these circumstances but I cannot see how this could be the result of some outside agency. Therefore, I am at a loss to explain these changes. What I need to discover is what agency changed these files and why. In the meantime I have removed the gdb, vim-enhanced and vim-X11 packages from that host. Has anyone else run across this sort of behaviour? Has anyone any idea as to what is going on here? -- *** E-Mail is NOT a SECURE channel *** James B.

Question about storage for virtualisation
by Nicolas Ross 03 Jul '12

03 Jul '12

Hi ! I'm about to deploy a new server that will host several virtual host for mainly website hosting purposes. My server will be a Xeon 3440 or 3450 with 32 gigs of ram (the max of that board). So I will have 8 logical cores. At the moment, I don't know how many vms I will have, in the order of 5 or 6. I am quite new to managing VMs, I did play alot with them over the course of the last couple of weeks. I used kvm to startup and manage my vms and my main source of info was this blog entry : http://blog.mattbrock.co.uk/2012/02/12/virtualisation-with-kvm-and-lvm-on-c… I have some general questions about VM. If I set vcpu let's say to 2-3 for a single vm, does this mean that those CPU are dedicated to that vm or many vm can share the same physicial cpus ? So, I was wondering what's the best for managing storage for VMs ? I see mostly recomandations for LV for storing VM's disks. It seem to helps to create snapshots for backup purposes. Is this the fastest way of creating backups ? And will data access be faster that if I use regular files ? In my case, the "main" setup of each vm is rather simple. The minimal OS, updates, my own httpd, my own php a couple of other packages. So restoring a VM from scratch can take less than an hour. So I was thinking of not taking snapshot of the whole VM and only sync the data partition. As for the guest paritions, I am accustomed of separating my servers disks with separate /, /usr, /var, /home and /data partitions. I can't recall today why I started doing this, 15 years ago, but I still like it that way and continue to do so. Do I still "need" to do this with VMs ? Thanks for the help !

Re occurring LTO5 hw issue
by aurfalien 03 Jul '12

03 Jul '12

Hi all, We have 2 LTO5 drives in a Quantum Scalar i500. Within a years time, we have gone through 4 drives total and luckily we are on support. We catch the problem by doing 2 verifies on the archives; a full virtual restore were the entire tape(s) are read and then a real selective restore were we test the restored data. We have 650TB on tapes within a years time. Any one have similar experiences with LTO5 drives? My data room may be a little dusty but nothing to sneeze at :) - aurf
