How to install and configure Flex. RAID 2. x (Flexible RAID) on Ubuntu Server. How to install and configure Flex. RAID 2. x on Ubuntu Server. NOTE: This guide has been written for Ubuntu Lucid Lynx 1. Ubuntu. Overview. You may have read already that I currently have six 2. TB drives in my server which hold all my CD, DVD & Blu- ray rips. Statistically speaking, the more drives you have the more likely you are to experience a drive failure at some point. As I obviously still own all the physical media I could re- rip them all in the event of such an occurrence. However, this would prove quite time- consuming and so I figured it's about time I implemented some sort of RAID system to protect the data on the drives. RAID is basically a mechanism which allows you to recreate the data on a failed drive using the data from the other drive(s) in the RAID array. It should be stressed that RAID is not a substitute for proper backups and so you should ensure important data is backed up properly. If you're not familiar with RAID then you can read all about it here. Traditional RAID systems operate at the system level and so you need to format your drives to implement your chosen RAID system. This can be irritating especially if you've already filled up your drives with data. Furthermore, if you experience multiple concurrent drive failures over and above the RAID tolerance level you've chosen then you lose ALL the data in the RAID array, not just the data on the failed drives. In my search for a suitable RAID system to implement on my server I came across Flex. RAID. Flex. RAID is a RAID system that aims to protect data rather than physical discs. Flex. RAID is not a file system but instead it sits on top of your existing file system. This means you can implement Flex. RAID without having to reformat your drives. Furthermore, the drives you want to protect with Flex. RAID do not have to all be the same physical size as each other. They don't even have to reside on the same physical machine. So, you could for example, add USB/e. SATA drives to your RAID array that physically live elsewhere on your network. Or use an external (USB/e. SATA) drive to hold the array parity leaving all the internal drives in your server for your data. If you have a NAS on your network you could add the data on that to the Flex.

RAID if you experience multiple concurrent drive failures over and above the chosen RAID tolerance level then you lose only the data on the failed drives, the data on the non- failed drives remains intact. I think so! At the time of writing there are two main flavours of Flex. ![]() RAID: . These two flavours were previously called Flex. RAID Basic and Flex. RAID Live! Fortunately that is now a thing of the past as the names explain what they are, assuming of course that you're familiar with the fundamental difference between real- time RAID and snapshot RAID! Real- time RAID is a RAID mechanism whereby the parity information is updated as soon as you make any changes to your data. This means that the Array is always up to date and all data can be re- constructed from parity if required. Snapshot RAID is a RAID mechanism whereby any changes you make to your data are not reflected in parity until you manually force a re- synch. Until such time as the array has been re- synched then any changed data is at risk since it cannot be re- constructed from parity. Once the Array has been re- synced then all data in the Array is once again protected. Whilst at first glance it may seem that Real- Time Flex. RAID is the most sensible flavour to use I decided to go for Snapshot Flex. RAID. Simply because I rarely change the data in the array (remember, it's all ripped data) and so do not need real- time synchronisation. Maintaining a real- time RAID parity can be quite resource intensive and I didn't feel this overhead was necessary in my case. I've scheduled Flex. RAID to automatically re- sync the array regularly so I don't have to remember to do it manually. Possible that recent ubuntu upgrade broke the audio. I had the audio working like week ago in one computer and now it. Building yourself a TV tuner server is definitely not a new thing for me. In fact, I did this almost precisely one year ago with mumudvb. Since then, I have learnt a. Tvheadend is a TV tuner server (also known as a PVR backend) and video streaming software for Linux supporting television signal tuning of DVB-S, DVB-S2, DVB-C, DVB-T. PINNACLE TV TUNER and Windows 7 6. Tuner Cards. Get hauppage 2. HD TV tuner for PC (PCI/PCIE).. Software is the best for XP, Vista, W7. It works well with media center or you can use hauppage Win. Tv software. I use mine as PVR and DVR in both HD and non- HD mode. ATI 6. 50 PCI/PCIE has hardware issues and software issues w/ Vista and W7. The hardware is prone to failure. ![]() ATI replaced my card 3x. Their updates are verly slow to come by. I tried Hauppage 1. For ATI i tried 6. PCI/PCIE, ATI 6. 00.. Hi guys, I am trying to install tvheadend. I then found this sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 379CE192D401AB61. I also tried Pinnacle and other less know brands. ATI originally came out as $1. HD Tuner.. W/ all the hardware and software issues about that product it now sells for $2.
