  • ZFS on Ubuntu error: Failed to load ZFS module stack

     

    If you see the above error in a fresh installation of ZFS on Ubuntu one cause may be that the package build-essentials wasn’t installed prior to installing the ubuntu-zfs package; run:

     

    sudo apt-get purge ubuntu-zfs

     

    then check for the remaining packages with the following:

     

    dpkg –list | grep zfs

     

    …and apt-get purge any remaining relevant ZFS packages.

     

    Then:

     

    sudo apt-get install build-essential

     

    …then install ubuntu-zfs as you did originally:

     

    sudo apt-get install ubuntu-zfs

     

    This time it should take properly. This isn’t the only cause of that error but on a fresh install with a new OS it’s one possibility.

  • Asus motherboard BIOS update error: CAP file not recognised EFI bios!

     

    If you see the above error – and you’re selecting what you’re sure is the proper CAP file – chances are you’re trying to use a USB disk formatted to NTFS rather than FAT32. Frustratingly, the error message for a corrupt/non-CAP file is the same as the error message you get when you’re trying to use an NTFS-formatted drive, which Asus Ez Flash 2 is not compatible with.

     

    The solution is simply to use a FAT32-formatted drive. If that doesn’t work double check that your file hasn’t corrupted during the download and is complete, and the right BIOS for the board.

  • esxcli: Update/patch produces “Could not download from depot” error

    In ESXi 5.1 you can patch using the following command:

     

    esxcli software vib install -d /path/to/patch.zip

     

    If you’re getting the following result (using ESXi510-20121001.zip as an example):

     

     [MetadataDownloadError]
    Could not download from depot at zip:/var/log/vmware/ESXi510-201210001.zip?index.xml, skipping ((‘zip:/var/log/vmware/ESXi510-201210001.zip?index.xml’, ”, “Error extracting index.xml from /var/log/vmware/ESXi510-201210001.zip: [Errno 2] No such file or directory: ‘/var/log/vmware/ESXi510-201210001.zip’”))
    url = zip:/var/log/vmware/ESXi510-201210001.zip?index.xml
    Please refer to the log file for more details.

     

    This results from not putting in the absolute path to the .zip – e.g. using:

     

    esxcli software vib install -d ESXi510-20121001.zip

     

    rather than:

     

    esxcli software vib install -d /vmfs/volumes/datastore/ESXi510-20121001.zip

     

    Putting in the full path to the .zip file should resolve that error.
