Recently when setting up a FreeIPA server I ran into the issue of the server resetting it’s hostname every time it rebooted. I had configured FreeIPA to use a different hostname than what the server was booted up with, and it was important that it kept that way otherwise FreeIPA would not start on boot properly.
Starting with RHEL/EL7 the drivers for the raid controller card, the P400i, are no longer loaded in by default. When you go to install Centos 7 on one of these you will likely see that it doesn’t detect your LD.
With the default drivers I initially was getting 56KB/s with this adapter and had to reset it every 3-5 minutes. I made some (crappy) tweaks and got up to 2MB/s. Which was enough to install vim and fix the problem.
