In this video we go from an unmountable pool to a mountable pool with corruption to using zdb to extract block-level data from a damaged dataset and then reassemble those blocks into a usable file. https://teksyndicate.com/videos/zfs-data-recovery-logan-got-his-groove-back Music: http://bit.ly/Trk2ik, Merch: http://epicpants.com Game Deals: https://teksyndicate.com/gamedeals Join the community: https://teksyndicate.com/user/register You can create a new account or join using your google, steam, facebook, openID, twitter, linkedin, yahoo, etc. If you have questions, comments, suggestions, or if would like to use a portion of this video please email us: inbox@teksyndicate.com For marketing (sponsorship opportunities) inquiries email info@teksyndicate.com Social: Twitter: https://twitter.com/teksyndicate Logan's Twitter: https://twitter.com/Logan_RTW Facebook: https://www.facebook.com/teksyndicate

  1. Should have backups.
  2. is it possible to recover data from FreeNAS raidz-1 consists from 3x3TB disks? Data was accidentally deleted.
  3. Great video. Thanks for showing it to us.
  4. I cannot imagine a universe where this video is can actually help someone.
  5. This is a great video. Wish it went into more detail. Too much was cut out. Why do you try to keep your videos so short. Does YouTube charge for the upload?
  6. I lost 2 TB hdd few days ago. It was single zfs file system. Freenas unable to import it. Ii was fault by ups. Is there any way to recover it with spend fortune? .
  7. At 9:04 why didn't you just do, JUST KIDDING I have no fucking clue what he is doing
  8. Out of curiosity how often were you scrubbing the pool?
    I've always sort of hoped that regular scrubbing and full disk surface checks would at least "kick up the dust" and if not identify problems themselves, make me more aware of any issues based on disk behavior.

    Also, not to be that guy, but are you doing backups now? I know it is pretty cost prohibitive but it makes a world of difference; although I doubt it would make for as exciting content. :-D
  9. Amazing
  10. Wendell - The God!
    Please make some videos on how to start with Linux modding & all advanced stuff. I'm now comfortable with basics
  11. I would like the knowledge to debug at that level, but I couldn't help thinking that if it was me I would just reinstall, replace faulty HDD and restore from my back-up. Save hours of time.
  12. mmm  interesting
  13. I saw the word "Foray" in the thumbnail and instantly knew it was Tek Syndicate.
  14. i bought a WD black 2 tera HDD....model ends in FEZ.... it worked for 9 months and then the drive motor for the read/write heads went bad.... was making a WEERRRR WOOOOO WEEERRRR

    ya... 9 months old.... my old hd blue 1 tera.... with 16,000 hours on it..... works a treat. 

    is it just me.... or are drives like HGST and WD going down hill?
  15. What did he say? He lost me @... I wrong my own kernel......
  16. Just sent a drive to Gillware and used your referral code. Thanks for the video :)
  17. i didn't understand much but i love this stuff :)
  18. This sounds magical.....because i don't understand even half of it...
  19. Why go through this trouble? You could just have restored it from your backup?
  20. Wendell FTW!  RaidZ2 all the way, it would have saved so much time.
