I currently have one of these setup with a 1260L (sandybridge) 16GB of RAM and running Server 2012 R2. 500 GB SSD in bay 1, 6 TB in bay 2, and 2 4 TB disk in the other bays. All are setup on the software raid as their own disk.
My current plan is to move the SSD to the ODD port, I am aware that I will need a floppy -> sata power cable + sata cable. I then wish to move over to CentOS or Arch instead of Server 2012 R2. The 6 TB has about 400 GB free, the other disks have about 2 TB used between them. My main question is, what will be the least awful way of migrating everything over to linux? I will be adding in another 4 TB disk after everything is moved, so I guess I will have to shuffle the 6 TB onto the other disks before hand and setup the 6 TB in linux.
Has anyone had any experience with migrating a plex server from windows to linux? I'm aware of how to do it from windows - windows, are there any specific things to do with linux?
Are there any "gotchas" to look out for when installing CentOS or any other distro on these servers?
