Replacing drive in RAID6

1st Official Post

    Hi, I'm new here, so I'm sorry if I'm breaking any rule I sould know about, but even with help of Google and forums search I cannot find anything - thread, post, guide - here on forum about replacing drive in RAID6.


    What I need is a guide how to replace one of the drives in RAID6. Or at least confirmation if I can use any guide about RAID6 using MDADM (like here: https://www.redhat.com/sysadmin/raid-drive-mdadm).


    I'm new to NAS stuff, and OMV itself as well, so to find about everything I need/should know before I'll start using array as my main home storage.

    What I have right now is RAID6 array with btrfs using my 8 3TB drives, one of them is red in SMART.

    I have replacement for it, so its not the problem. To be true I knew I'm using falling drive in array, so I could go through replacing drive before I copy all data I want to be there and remove it from it's source.


    It will give me knowledge for the future and, as there is nothing unrecoverable than even if I break something I want lose anything important.


    Thanks in advance :)

    Raid Management, select the raid, on the menu click remove, from the dialog select the failing drive click OK, this will remove the drive from the array.


    Shutdown, remove the failed drive, install new drive, restart


    Login to OMV, Storage -> Disks select the new drive click wipe on the menu and select short, wait for this to complete.


    Raid Management, select the raid, on the menu click recover, a dialog should display the new drive which you have just wiped, select it, click OK and the raid should display as rebuilding.

    Raid is not a backup! Would you go skydiving without a parachute?
