Raid change issue when new disk added

Post by novisiblemeans »

Hi, I have an F5-221 NAS. I've been running it with 3 x 8Tb disks in a Raid 1 configuration for about a year now. A couple of weeks ago I added a new 12Tb HDD as it was running low on space. When I inserted the new drive it proceeded to add the new disk to the old storage volume and change it to a Raid 5 configuration, with the result that I have no new storage space.

I don't need Raid 5 as I have all my files backed up elsewhere.

However I cannot see any way to revert to Raid 1 and free up storage space.

Hope you can help me.

Thanks in anticipation.

You should not continue if you don't want RAID5 configuration. The new added drive could be set as Single by clicking "Create" at storage pool.
Since you have backup of all your data, you can delete the current volume and storage pool and create a new RAID by selecting the first three drives as RAID1.

So the only way I can do that is to delete ALL my data, erase ALL the disks and start again?
