TL;DR : I want to expand my storage capacity and would like to double check with you if I can simply connect two new drives on my NAS without losing redundancy or any data on my actual RAID.
I’m not sure if I’m in the proper part of this forum to ask questions on this subject but feel free to move my post if necessary.
I’ve started my NAS with 3 x 1 TB hard drives configured in BTRFS (RAID 5).
I don’t have a lot of margin of error with only one drive failure accepted before losing every content on my NAS so I would like to add 2 more disks (same size, same brand).
I’m just not sure if BTRFS will let me expand my volume capacity without losing any data.
I’ve found this quick guide on Synology and it doesn’t seem to be a problem with BTRFS (which it is with ZFS for example) but I would like to double-check with you before ordering my two extra drives.
Thanks for the support,
Have a great day.
