ZPOOL-REPLACE(8) System Manager's Manual ZPOOL-REPLACE(8) NAME zpool-replace -- replace one device with another in ZFS storage pool SYNOPSIS zpool replace [-fsw] [-o property=value] pool device [new-device] DESCRIPTION Replaces device with new-device. This is equivalent to attaching new-device, waiting for it to resilver, and then detaching device. Any in progress scrub will be cancelled. The size of new-device must be greater than or equal to the minimum size of all the devices in a mirror or raidz configuration. new-device is required if the pool is not redundant. If new-device is not specified, it defaults to device. This form of replacement is use- ful after an existing disk has failed and has been physically replaced. In this case, the new disk may have the same /dev path as the old de- vice, even though it is actually a different disk. ZFS recognizes this. -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 the replacement has completed before returning.
