ZPOOL-ATTACH(8) System Manager's Manual 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 existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mir- ror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately and any running scrub is cancelled. -f Forces use of new_device, even if it appears to be in use. Not all devices can be overridden in this manner. -o property=value Sets the given pool properties. See the zpoolprops(7) manual page for a list of valid properties that can be set. The only property supported at the moment is ashift. -s The new_device is reconstructed sequentially to restore redun- dancy as quickly as possible. Checksums are not verified dur- ing sequential reconstruction so a scrub is started when the resilver completes. Sequential reconstruction is not supported for raidz configurations. -w Waits until new_device has finished resilvering before return- ing.
