With the recent release of Openfiler 2.99 there has been an on-going issue with an inability to create certain software RAID arrays. This is present in the beta and final release of the software and was getting frustrating, however there is a fix.
If you are going to be installing Openfiler 2.99 and discover that you’re not able to create software RAID 1 arrays then the following will resolve that for you.
You’re going to need to launch a secure console to type in some command lines, to do that follow these instructions.
On the Openfiler Console, click on System.
Then click on Secure Console.
Choose your preferred connection profile (default is as above), click connect.
Enter the root password (created during the installation process) and this will launch the Secure Shell.
Now you need to type the following commands into the shell.
conary update mdadm=openfiler.rpath.org@rpl:devel/2.6.4-0.2-1
This will install the correct mdadm files, once installed type the next command in.
ln -s /sbin/lvm /usr/sbin/lvm
This ensures that the GUI is populated correctly.
This will then allow you to create all of the software RAID types without issue.
