zpool-attach.8:
NAME
zpool-attach — attach new device to existing ZFS vdev
SYNOPSIS
zpool attach [-fsw] [-o property=value] pool device new_device
DESCRIPTION
Attaches new_device to the existing device. The behavior differs depend‐
ing on if the existing device is a RAIDZ device, or a mirror/plain
device.
If the existing device is a mirror or plain device ...
If the existing device is a RAIDZ device (e.g. specified as "raidz2-0"),
the new device will become part of that RAIDZ group. A "raidz expansion"
will be initiated, and the new device will contribute additional space to
the RAIDZ group once the expansion completes. The expansion entails
reading all allocated space from existing disks in the RAIDZ group, and
rewriting it to the new disks in the RAIDZ group (including the newly
added device). Its progress can be monitored with zpool status.
