Hi! I’m about to upgrade my homelab from a RAID1 with two 8TB drives to a new
one with two additional dives. I mostly use my homelab for Nextcloud (Documents,
photos, audiobooks, …), media storage, jellyfin and whatever docker container I
think would be cool to self host. Since data availability is less of an issue
for me and Backup Space is limited, I’m thinking of ditching the RAID in favour
of btrfs and for additional safety: use one of my 8TB drives as a Snapraid
parity drive. At least for the personal nextcloud data - I can get the media
files from elsewhere in case of data loss. However, tutorials of btrfs with
Snapraid are a bt thin on the ground and with this being my first time using
btrfs, I’m a bit hesitant. Some people suggest MergerFS with btrfs + snapraid,
but I fail to see the advantage of MergerFS with btrfs. So… is this actually a
good Idea? It seems to me that this would be a good tradeoff and I could wait a
bit before the next time I need to buy a storage upgrade. Thanks in advance. :)
Cross-posting by hand because of higher reach. I hope that’s ok (didn’t find any rules saying otherwise)
You might want snapraid-btrfs too if you go this way, which does sync on read-only snapshots instead of live data.
