# Syncthing share enrol on ZFS subvolume
1. Create zfs subvolume: `zfs create ...`
2. Set zfs-auto-snapshot property (for zfstools) : `zfs set ..`
3. Create share in Syncthing web GUI
4. Ignore .zfs folder (to not propagate to connected peers): filter `.zfs`
# Syncthing migrate to zfs subvolume
```
# zfs create zpool/data/syncthing/shared/...
# zfs set snapdir=hidden zpool/data/syncthing/shared/...
(optional) # zfs set copies=2 zpool/data/syncthing/shared/...
# rsync --perms --archive --progress /data/syncthing/shares/... /data/syncthing/shared/...
# echo ".zfs" > /data/syncthing/shares/.../.stignore
# zfs set com.sun:auto-snapshot=true zpool/data/syncthing/shared/...
# zfs list -t snap zpool/data/syncthing/shared/...
```
# ZFS dataset datablock copies
For extra redundancy amount of datablock copies can be set and tested:
```
# zfs create data/test-dataset/dataset-1
# zfs list
# zfs set copies=2 data/test-dataset/dataset-1
# zfs get copies data/test-dataset/dataset-1
root@mango:/data/test-dataset/dataset-1 # dd if=/dev/random of=testfile bs=64K count=1024
1024+0 records in
1024+0 records out

## Syncthing per-share zfs subvolume
For important shares data we set copies=2 and checksum=sha256
```
# zfs create zpool/syncthing/shares/myshare
# zfs set copies=2 zpool/syncthing/shares/myshare
# zfs set checksum=sha256 zpool/syncthing/shares/myshare
```
Which shares:
* jerry/pyrotechnics
* jerry/private
## ZFS snapshot visibility
Hide the `.zfs/snapshot` directory in the dataset so Syncthing doesn't sync it by accident when not ignored via `.stignore`:
```
# zfs list -t snapshot zpool/data/syncthing/shared/jerry/private
# zfs get snapdir zpool/data/syncthing/shared/jerry/private
# zfs set snapdir=hidden zpool/data/syncthing/shared/jerry/private
# ls /data/syncthing/shared/jerry/private/.zfs/snapshot
```
To make it visible again
```
# zfs set snapdir=visible
```
