  • missing disks, dump devices, mirroring, etc. – Waldemar Mark Duszyk – Since, we are pretty much always learning …. Some of us on a more elementary, intermediate, or advanced level but regardless of the level we all always learn or re-learn (because what we have mastered we had an ample time to forget – not doing it for a while), here it is a reminder of how to deal with a volume group (in this case it is rootvg which for some reasons lost one of it disks. The loss could be a function of SAN, VIO or other event. It could be a permanent loss – a disk is dead, broken, no longer functioning or the loss was/is temporary in nature; AIX kernel detected a timeout (without any disk errors associated with device failure) long enough for the kernel to mark the disks missing.
  • Authenticating RedHat with ActiveDirectory and Kerberos – Waldemar Mark Duszyk – One of my previous posts deals with authentication of RedHat LINUX using Tivoli Directory Server (TDS LDAP). As I was working on this project, my colleague Igor was busy configuring RedHat authentication with Active Directory and Kerberos (already configured on AD).

  • Introduzione a GlusterFS: uno storage scalabile e distribuito – Mia mamma usa Linux! – GlusterFS è un file system open source distribuito e scalabile orizzontalmente, la cui capacità può essere dinamicamente espansa mediante l’aggiunta di nuovi nodi. GlusterFS è in grado di arrivare a gestire fino a diversi peta byte, migliaia di client e diverse aree dati (storage) organizzandole in blocchi che rende accessibili su Infiniband RDMA (remote direct memory access, fibra ottica) o connessioni TCP/IP.
    Le risorse “memoria e disco” vengono rese disponibili sotto un unico punto di condivisione e tali risorse possono essere montate dai client mediante tre diversi protocolli: CIFS, NFS od il client nativo Gluster.
    Questo articolo effettua una prova su strada di GlusterFS, introducendone i concetti e sperimentandone le funzionalità.
  • 800 Open Source Packages for AIX Ready for Downloading NOW (AIXpert Blog) – […] Instead of getting annoyed and complaining (like me), Michael decided to go and fix this short fall himself and a personal project and "give back" to AIX users world wide. So he compiles the open source packages on AIX and makes them freely available for download from:   http://perzl.org
       This website covers the AIX pre-compiled binaries for 800+ open source packages as RPM's and the other his hot project Ganglia for POWER, AIX and Power Linux […]

  • Disaster: LVM Performance in Snapshot Mode – MySQL Performance Blog – In many cases I speculate how things should work based on what they do and in number of cases this lead me forming too good impression about technology and when running in completely unanticipated bug or performance bottleneck. This is exactly the case with LVM
    Number of customers have reported the LVM gives very high penalty when snapshots are enabled (leave along if you try to run backup at this time) and so I decided to look into it.
  • Netexpertise » Mysql Ultra-Fast Backup with LVM – It is generally good practice to respect the two following points when backing up databases. The backup has to be:
    consistent
    fast
    Consistency is easily achieved putting a read lock on all tables beforehands. However, this isn’t always applied, and WILL definately lead to a database integrity problem at some stage.
    Once a lock has been set on the database, the backup has to be as quick as possible, all write instructions being held in the queue.

  • Five Tips for a Better sendmail Configuration – O’Reilly Media – Unix vendors bundle sendmail with the operating system and ship it out preconfigured. It is very easy to install the OS and use the sendmail configuration delivered with the system. Don't be fooled by this apparent simplicity. In the long run, it is better to take charge of your fate. Creating a custom sendmail configuration using current software and features selected for your environment will give you better performance, reliability, security, and maintainability. Here are some tips to get you started on building a better sendmail configuration.

  • mylvmbackup – mylvmbackup is a tool for quickly creating backups of a MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations, while the actual file backup proceeds.

  • Account Administration – disciplinux – Change AIX password non-interactively

        Use the chpasswd utility to change the password.

  • Tightening Default AIX Sendmail – disciplinux – I started looking at the default AIX configuration of sendmail for the SMTP Open Relay issues. Previously I had sent a configuration change to
    allow only specific relay-domains. However, it appears that the default sendmail configuration sets "PROMISCUOUS_RELAY" which overrides the
    RELAY-DOMAINS directive.
  • Configure sendmail to start logging Subject in maillog | www.linux4beginners.info – In this article we will learn how to configure sendmail so that you can log "Subject" in /var/log/maillog as by default sendmail does not log Subject to maillog file.

    This is really interesting. Business people many times are interested in getting mail log files analyzed. To analyse mail logs they need various field to appera in mail logs. e.g. "From", "To", "Subject" etc from the sent email. By default sendmail logs From and To fields but it does not log Subject field. In this article you will learn how to enable sendmail to log "Subject".

  • Nagrestconf README – What is Nagrestconf?
    Nagrestconf is a REST interface and configuration GUI for Nagios.
    Nagrestconf is written in Bash and PHP.
    Specifically, Nagrestconf:
    allows Nagios configuration files to be written using a REST api.
    allows the server to be restarted using the REST api.
    provides a configuration Web GUI built on the REST api.
    It can be useful for:
    Bulk loading
    Bulk editing
    Automation
    Catching common configuration mistakes
    Configuration Delegation (using additional tools)
    Distributed monitoring (using additional tools)

  • Oracle Linux: A better alternative to CentOS – We firmly believe that Oracle Linux is the best Linux distribution on the market today. It's reliable, it's affordable, it's 100% compatible with your existing applications, and it gives you access to some of the most cutting-edge innovations in Linux like Ksplice and dtrace.

    But if you're here, you're a CentOS user. Which means that you don't pay for a distribution at all, for at least some of your systems. So even if we made the best paid distribution in the world (and we think we do), we can't actually get it to you… or can we?

    We're putting Oracle Linux in your hands by doing two things:

    We've made the Oracle Linux software available free of charge
    We've created a simple script to switch your CentOS systems to Oracle Linux
    We think you'll like what you find, and we'd love for you to give it a try.

  • configure time service on AIX host – Waldemar Mark Duszyk – First, you have to decide/select the appropriate devices to be your time providers. It could be one or more “official/public” time servers or maybe your routers. When you decide what these servers are you should validate that they deliver what you need and that you are (your host) is capable to receive and use what is delivered.

  • MobaXterm-Plugins – bananahut.net – This page contains a few third-party MobaXterm plugins that I packaged myself. MobaXterm is an enhanced terminal for Windows build on top of cygwin. It is self-contained and doesn't require installing or managing a ton of dependencies and things like Cygwin.
  • Mirrorvg without locking the volume group – AIX Health Check – When you run the mirrorvg command, you will (by default) lock the volume group it is run against. This way, you have no way of knowing what the status is of the sync process that occurs after mirrorvg has run the mklvcopy commands for all the logical volumes in the volume group. Especially with very large volume groups, this can be a problem.

    The solution however is easy: Make sure to run the mirrorvg command with the -s option, to prevent it to run the sync. Then, when mirrorvg has completed, run the syncvg yourself with the -P option.

  • Portable Ruby | YELLOSOFT – Now you can run Ruby from a USB drive!

    AllInOneRuby is a wonderful automated way to generate Ruby binaries. We just made one ourselves for those out there that don't have access to a full Ruby installation. We ran allinoneruby.rb to generate the binaries: version 1.8.6-26 for Windows and 1.8.6.111 for Linux.

    To make it easier to run Ruby scripts, we included some run files. Double click them to begin running Ruby programs. Edit them to point to your scripts.

    Mac users, don't feel left out! Mac OS X 10.4 and later come with Ruby built-in! So copy your Ruby scripts along with this Portable Ruby package onto a USB drive. If you designed your programs correctly, they'll now be runnable on Windows and Linux too!
