    `Please suggest what step will save my Raid 5 without loosing data` With two dead drives in a RAID5, I'd hope my backup is up to date because more likely then not, that array is gone for good. When you restore, switch to a better RAID type. If you have no good backup, hire a data recover company ... – Sven Mar 16 '18 at 18:32
  • Should i press the "F" aur "C" – Rohit Singh Mar 16 '18 at 19:02
  • Try 'C' and 'V' :) – Chopper3 Mar 16 '18 at 19:15
  • please suggest clearly what i need to do to start my server again – Rohit Singh Mar 16 '18 at 19:27
  • Restore from backup. RAID is not for preserving data, it's for maintaining availability. – Skyhawk Mar 16 '18 at 19:34

    By the way: RAID5 is a terrible, horrible, no good, very bad RAID. If you're looking for sensible defaults, choose RAID6 if you want cheap and slow across many drives, or RAID1+0 if you want fast but not cheap. If you had been using RAID6 or RAID1+0 this error would not have taken down your array. – Skyhawk Mar 16 '18 at 19:38
  • can i power off the server and replace these 2 faulty HDD with new one and then start ? after that i think it will start rebuilding right ? – Rohit Singh Mar 16 '18 at 20:43

    @RohitSingh: No, it won't. RAID5 can withstand the failure of a single disk. If two disks fail, your data is lost except you either have a good backup or spend a lot of money for a professional data recovery service (the second option is not guaranteed, they can't do magic). – Sven Mar 16 '18 at 23:28

Restore from last known good backup, oh and don't use RAID5.
