I will install CloneZilla SE on a Debian Etch server in this tutorial. The systems that you want to clone can use whatever Linux distribution you prefer.

  • Reducing Disk IO By Mounting Partitions With noatime

    tux Author: Falko TimmeTags: Comments: 9

    Reducing Disk IO By Mounting Partitions With noatime Linux has a special mount option for file systems called noatime. If this option is set for a file system in /etc/fstab, then reading accesses will no longer cause the atime information (last access time - don't mix this up with the last modified time - if a file is changed, the modification date will still be set) that is associated with a file to be updated (in reverse this means that if noatime is not set, each read access will also result in a write operation). Therefore, using noatime can lead to significant performance gains.

  • NIC Bonding On Slackware 12.1

    slackware Author: mstjohn1974Tags: , Comments: 6

    NIC Bonding On Slackware 12.1 I was standing in front of a problem while I built a NFS Storage Server. It is necessary for me to have redundancy in every point of view. I solved all redundancy issues I had by using server hardware with redundant power supplies, a Raid 1+ 0 Raid array and two UPS’s one for each power supply. The only thing left in my mind was what about a network failure? Well just use the two Gig NIC’s and hook each of them up to its own switch. Great idea but how do I get them acting as one unit speak one single IP? NIC Bonding was my solution. After a couple of hours researching on the Internet stumbled upon the build in solution by using ifenslave.
