Configuring a Disk for a ZFS Non-Root File System

Language:

A disk that is set up for a non-root ZFS file system is relabeled automatically when the pool is created or when the disk is added to the pool. If you use a whole disk either to create a pool or to add to a ZFS storage pool, an EFI label is applied.

Most modern bus types support hot-plugging, which enables a system to immediately recognize a disk that you insert into an empty slot. For more information about hot-plugging devices, see Dynamically Configuring Devices.

How to Set Up a Disk for a ZFS Non-Root File System

This procedure assumes that you have installed the replacement disk on the system.

For information about adding disks, see Adding or Replacing Disks for ZFS File Systems.

Become an administrator.
Launch the Format utility to verify that the new disk is listed in the output and therefore accessible.
```
# format
```
Type quit to exit the Format utility.
Replace the root pool on the new disk.
```
# zpool replace non-root disk
```
If required, bring the new disk online.
```
# zpool online non-root disk
```
Verify that the new disk is resilvered.
```
# zpool status non-root
```

Attach the new disk to the ZFS pool.

# zpool attach root-pool old-disk new-disk
