RAID 5 to RAID 6

  • Hi!


    My current setup is 4 x 6TB in a RAID5 setup. My plan was to add 4 more disks and then change it to 8x6TB in RAID6.


    My question is which way is the fasted? (I do have all of my data backed up on a separate server)


    1. Erase the current RAID 5 and then re-create a new RAID 6 with all the disks
    2. Start with adding one disk and change from RAID5 to RAID6 and then add the other 3 disks?


    My system is running OMV4


    Suggestions?

  • Hi,


    the first option will be faster and not so stressful for your existing 4 disks.


    Option 2 will rebuild your raid with every new added disk and split up all your data and generate new parity keys.



    Cheers
