Increasing Raid 1 Storage Capacity

Post by Gandalf1369 »

I have a F2-220 (2 disk) NAS running Plex. It has been almost 2 years and it has performed very well. I have two 5GB hard drives and am at 72% capacity right now. The version of TOS is 4.1.30.

I have a couple of questions about swapping those two 5GB drives for larger ones without having to redo my entire Plex movies and database.

1. Is it possible with a Raid 1 configuration to even do what I'm thinking of ??? i.e. replacing the 5GB drives with larger ones.
2. If it is possible exactly how can I do it ?? Is it just as easy as replacing the original drives, one by one, with the larger capacity drives. Would doing this give me more storage space once the Raid 1 has been rebuilt ??

Any help or hints would be greatly appreciated.

Thanks . .

Just as you expected,you can swap the one drivre at a time for your raid1。When the first drive is synchronized,your can swap the next drive.

Thank you for the quick reply.

Are you saying that it is possible to increase the storage space in my Raid 1 setup by simply replacing the hard drives one by one ?? In other words, I currently have two 5GB drives in the F2-220 - the Raid 1 configuration gives me an actual storage capacity of 5GB. If I replace those hard drives with 8GB drives (again one by one and allowing the Raid to rebuilt itself after each drive replacement) will I then have a reported storage space of 8GB ?? Will I have to do anything within TOS to enable the extra storage to be recognized??

Sorry if I am being dense but I want to make sure before I go ahead and replace the drives.

Thank you.

Your understanding is correct.
But I don’t know how you got the 5GB drive?
