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
