# How to Migrate a ZFS Root Pool and Boot System to a New Disk
|
||
|
||
🪛 Goal
|
||
|
||
Migrate boot system and ZFS root pool from one disk to another, preserving bootability and data integrity.
|
||
|
||
Dont forget to Keep a rescue USB handy in case you need to recover the bootloader.
|
||
|
||
**1. Partition the New Disk:**
|
||
|
||
*Identify disks using lsblk or fdisk -l. and recreate partitions.*
|
||
|
||
|
||
**2. Format the EFI Partition:**
|
||
|
||
if using UEFI boot:
|
||
|
||
*Exemple using proxmox host os:*
|
||
|
||
``` bash
|
||
proxmox-boot-tool format /dev/sdY2*
|
||
```
|
||
|
||
**3. Attach New Disk to ZFS Pool:**
|
||
|
||
*This will mirror the pool temporarily:*
|
||
|
||
``` bash
|
||
zpool attach rpool /dev/sdX3 /dev/sdY3
|
||
```
|
||
|
||
**4. Wait for Resilvering:**
|
||
|
||
*Monitor progress:*
|
||
|
||
``` bash
|
||
zpool status rpool
|
||
```
|
||
|
||
**5. Detach Old Disk:**
|
||
|
||
``` bash
|
||
zpool detach rpool /dev/sdX3
|
||
```
|
||
|
||
**5. Update Boot Order:**
|
||
|
||
*Ensure your BIOS/UEFI is set to boot from the new disk.*
|
||
|
||
🧠 Notes
|
||
|
||
If you don’t want to mirror temporarily, you can also:
|
||
|
||
- Create a new ZFS pool on the new disk.
|
||
- Use zfs send | zfs receive to migrate datasets.
|
||
- Reconfigure bootloader manually.
