Hi all, I'm about to rebuild my MythTV backend and have done a bit of reading about unraid. What I currently use is: 2* 5Tb 2.5" USB external HDD mdraid on /dev/sdd1 and /dev/sdc1 set up as RAID1 /dev/md0 is VG vg_storage vg_storage has my LVs in it The person who described this to me about ten years ago put it as "... a delicious sandwich!" (The mdraid+LVM bit) So I had to try this sandwich I'm going to pull the 5Tb drives out of their enclosures, mount them internally, add a 3rd 5Tb drive and convert to RAID5 (no data loss). So this will be a traditional RAID setup, I will have to keep an eye on the SMART status of the HDDs (or use some other method, I have used nagios in the past, but that seems like a heavy solution just for doing HDD health monitoring...) With unraid, I know that there is full parity is stored on each drive, and if multiple drives fail you can just plug any one of the other drives into another computer and get the files off it, there are actual partitions with real filesystems on each drive. unraid also has virtualisation built it. And there's a cost, depending on how many drives you have in the system. My use case is pretty simple, mythtvbackend doesn't need a lot of resources except CPU when there's commercial detection going on, it's going to be serving files via SAMBA (and not much), and playing recordings to the frontends. Am I missing something amazing from the unraid stuff? And isn't there a free version?
