  1. Linux and TRIM with lvm and dm-crypt on SSDs.

    Tue 26 February 2013

    I had made the assumption that TRIM was enabled by default nowadays. Apparently not. To enable it for your filesystems, edit /etc/fstab and add "discard" as a mount option:

    /dev/mapper/vg_foo-lv_home /home                   ext4    defaults,noatime,discard        1 2
    /dev/mapper/vg_foo-lv_swap swap                    swap    defaults,discard        0 ...

    pref.motionGrab = "FALSE"
    pref.motionUngrab = "FALSE ...
  4. One computer to rule them all

    Thu 09 February 2012

After reading success stories from people using VGA passthrough with Xen i decided to give ...

  5. Linux and Sandy Bridge PCI Woes

    Tue 31 January 2012

    I put together a sandy bridged based server a while ago with 2 PCI intel network cards. However, it didn't turn out to work very well. After putting some load on the network it would become unbearably slow with error messages like this in the syslog:

    irq 16: nobody ...
