  • Centos PXEBoot NetInstall Failure - Pane is dead


    ValueError: new value non-existent xfs filesystem is not valid as a default fs type Pane is dead From what I read this is misleading and has to do with the fact that the initrd and kernel are mismatched. This is a hard situation because for some older hardware I am using the Centos Plus kernel which has modules that I require for an older server/NIC.  This seems to have cropped up in the past few months and there is no simple fix........
  • Ubuntu/Debian/Linux won't boot and drops to Busybox shell after cloning HDD with dd


    I don't recall having this issue in the distant past but nowadays at least Debian seems to be very picky about this. I used dd to copy one hard drive to another and tried booting it.  Everything seemed fine with grub working but each time it would drop to the busybox shell.  There is no particular error so this is misleading. Normally the first things you would check are to make sure your fstab is correct (that the UUID is correct) and that you've updated grub.&........

  • Centos how to upgrade from PHP 5.2 to 5.3 without downtime

You may need to upgrade to PHP 5.3 to run Joomla or many other reasons. Your host needs to use PHP 5.2.4 or higher to run this version of Jo........
