G+_paul poco Posted March 28, 2016 Share Posted March 28, 2016 Can you guys look at unRaid 6.1? What is involved in migrating an existing Ubuntu Linux system? Setup the raid arrays and use the box to use KODI on the local video card. Plex server, etc Link to comment Share on other sites More sharing options...
G+_Travis Hershberger Posted March 28, 2016 Share Posted March 28, 2016 I really don't like the description of this from the video. To do Software Defined Storage right, you need more options than a single parity drive today. The ONLY way to use a single parity drive safely today is in an all SSD array. Really what I'd want to see from something like this is tiering, where you could have certain things mirrored, triple mirrored, or Backblaze style "shard" for many parity bits. https://www.backblaze.com/blog/vault-cloud-storage-architecture/ Link to comment Share on other sites More sharing options...
G+_Andre Dault Posted March 29, 2016 Share Posted March 29, 2016 I've been using unraid for a few years now can I have not been disappointed yet. I've had one drive failure where I recovered without issue. I've been able to upgrade my drives more than once, again without issue yet. I like it for a few reasons, you have parity for your data that protects you from drive failure while being very efficient. For example, a RAID 5 system needs to spin all disks to make your data available, this system only spins up the one drive that contains your data, nothing else. Also, if by some fluke you have more than one drive fail, you will still have access to all the data that is on the drives that did not fail as the data is not stripped on many drives. BTW, with ver 6.2 you will be able to lose 2 disks in your array. You do however lose some performance compared to other systems but for my intended use, media streaming, it works just fine. Some have managed to get 10GB threwput https://lime-technology.com/10gbps-over-smb-on-a-45drives-storinator/ Also, the ability to use plugins, dockers and VM's in ver 6 has proved to be quite interesting.

G+_paul poco Posted March 29, 2016 Author Share Posted March 29, 2016 Andre Dault is there a way to have data already on the drives not destroyed when setting up? Do all the drives need to be the same size? Is it easy to add more drives later? Is there a way to convert an existing Ubuntu install to VM to use after unRaid is setup? Is there a Docker for Eventghost to use USB-UIRT exclusively? Link to comment Share on other sites More sharing options...
G+_Andre Dault Posted March 30, 2016 Share Posted March 30, 2016 ........ is there a way to have data already on the drives not destroyed when setting up? - not sure, I always let the array format them, it's uses XFS Do all the drives need to be the same size? - No, the parity drive needs to be as big as your biggest drive, that is all. I have a 4TB, 4TB, 2TB, 2TB and 1.5TB for a total of 9.5TB of usable space. Is it easy to add more drives later? - yes, you can add some or change some for bigger ones. Is there a way to convert an existing Ubuntu install to VM to use after unRaid is setup? - I'm sure there must be, it uses KVM so I'm sure there must be a physical to virtual conversion somewhere. Is there a Docker for Eventghost to use USB-UIRT exclusively? - not sure, I've never tried or looked into it. Link to comment Share on other sites More sharing options...
