SnapRAID / MergerFS
Setup
https://zackreed.me/setting-up-snapraid-on-ubuntu/
Partitioning a new data disk
Note: "-m 2" here reserves 2% of the filesystem for root-owned files (eg. .../.snapraid/content)
sudo parted -a optimal -s /dev/sdX -- mklabel gpt mkpart primary 0% 100% sudo mkfs.ext4 -m 2 -T largefile4 /dev/sdX1
Partitioning a new parity disk
Note: "-m 0" here reserves 0% of the filesystem, ensuring that the parity disks are slightly larger than the data disks
sudo parted -a optimal -s /dev/sdX -- mklabel gpt mkpart primary 0% 100% sudo mkfs.ext4 -m 0 -T largefile4 /dev/sdX1
Adding a new data disk to mergerfs
From within the root of the mergerfs filesystem (eg. =/srv=)
xattr -w user.mergerfs.srcmounts '+>/mnt/data/disk04' .mergerfs
Forcing a resync
sudo snapraid sync
