  • 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.

  • 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.

  • Keeping an eye on TSM volumes – […] I wrote a quick script which tells me when volumes in TSM (Tivoli Storage Manager) have access and/or media issues and shoots me off an email. The script does two things:<br />
    1) Checks for volumes which are NOT in the states READWRITE or OFFSITE.<br />
    2) Checks for volumes which have a read/write error count >0.<br />
    I’m sure that most people running TSM in their environment have some sort of daily reporting that gets sent out. If that’s the case, you can simply extract the SQL from the script and use it in your own reporting tools.<br />

  • [ubuntu] How to install Windows 7 as a KVM Virtual Machine under Ubuntu … – Well one reason I do it is now I don't have to have a Dual Boot setup on my machine. <br />
    <br />
    Now I always boot into Ubuntu initially and if I need Windows running I just goto System Tools – Virtual Machine Manager (or the command line) to start up Windows XP, Vista or Win7. <br />
    <br />
    Once started it is running concurrently with my Ubuntu Linux so I can easily switch back & forth from Ubuntu to Windows while running applications in BOTH operating systems! <br />
    <br />
    Better than dual-boot where your choice is run one or the other but NOT both simultaneously.<br />
    <br />
    So whether you currently dual boot to WinXP, Vista or some other Operating System you can now use KVM on Ubuntu
