# ZFS stuff
|
||||
|
||||
**In case of drive failure, go [here](#restore-after-drive-failure)!**
|
||||
|
||||
## Initial setup
|
||||
|
||||
Create partition table and partitions on drives:
|
||||
|
||||
```sh
|
||||
fdisk /dev/sd{$LETTER}
|
||||
```
|
||||
|
||||
```txt
|
||||
g
|
||||
# create 4g partition (ZFS)
|
||||
n
|
||||
\n
|
||||
\n
|
||||
+2T
|
||||
# create 12g partition (mergerfs (for media))
|
||||
n
|
||||
\n
|
||||
\n
|
||||
\n
|
||||
# write
|
||||
w
|
||||
```
|
||||
|
||||
format mergerfs/media partitions:
|
||||
|
||||
```sh
|
||||
mkfs.xfs /dev/sd{$LETTER}2
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
Set up ZFS pool:
|
||||
|
||||
```sh
|
||||
zpool create storage raidz1 /dev/sdb1 /dev/sdc1 /dev/sdd1
|
||||
```
|
||||
|
||||
set mountpoint:
|
||||
|
||||
```sh
|
||||
zfs set mountpoint=/mnt/user storage
|
||||
```
|
||||
|
||||
## Restore after drive failure
|
||||
|
||||
```sh
|
||||
zpool replace storage $NEW_ZFS_PARTITION
|
||||
zpool status storage
|
||||
```
