# ZFS
|
|
|
|
Swan runs its root on ext4. The ZFS drives are managed imperatively (this
|
|
[disko configuration](../disks/zfs.nix) is an unused work-in-progress).
|
|
|
|
The basic ZFS settings are managed [here](../modules/nixos/hardware/zfs.nix).
|
|
|
|
## Creating a New Dataset
|
|
|
|
```
|
|
sudo zfs create tank/mydataset
|
|
sudo zfs set compression=zstd tank/myzstddataset
|
|
sudo zfs set mountpoint=/data/mydataset tank/mydataset
|
|
```
|
|
|
|
## Maintenance
|
|
|
|
### Get Status
|
|
|
|
```
|
|
sudo zpool status
|
|
```
|
|
|
|
### Replace Disk
|
|
|
|
```
|
|
sudo zdb
|
|
sudo zpool status -g # Show by GUID
|
|
sudo zpool offline tank <GUID>
|
|
sudo zpool status
|
|
# Remove old disk, insert new disk
|
|
sudo zdb
|
|
sudo zpool replace tank <OLD GUID> /dev/disk/by-id/<NEW PATH>
|
|
sudo zpool status
|
|
```
|
|
|
|
## Initial Setup
|
|
|
|
```
|
|
sudo zpool create tank raidz1 sda sdb sdc
|
|
sudo zpool set ashift=12 tank
|
|
sudo zpool set autoexpand=on tank
|
|
sudo zpool set compression=on tank
|
|
```
