Hi,
When it comes to replacing a disk in a zfs pool, the replace action does the following;
The "replace" action migrates data to the new device from the damaged device or from other devices in the pool if it is in a redundant configuration.
When the command is finished, it detaches the damaged device from the configuration, at which point the device can be removed from the system.
Hopefully your disk source is undamaged, so it will just migrate the data without significant risk.
Regards

devfs.conf
DEVFS.CONF(5) BSD File Formats Manual DEVFS.CONF(5)
NAME
devfs.conf -- boot-time devfs configuration information
DESCRIPTION
The devfs.conf file provides an easy way to set ownership and permissions, or create links for devices available at boot.
It does not work for devices plugged in and out after the system is up and running, e.g. USB devices. See devfs.rules(5) for setting owner-
ship and permissions for all device nodes, and devd.conf(5) for actions to be taken when devices are attached or detached.
Lines starting with a hash sign ('#') and empty lines are ignored. The lines that specify devfs.conf rules consist of three parameters sepa-
rated by whitespace:
action The action to take for the device. The action names are only significant to the first unique character.
devname
The name of the device created by devfs(5).
arg The argument of the action.
The actions currently supported are:
link This action creates a symbolic link named arg that points to devname, the name of the device created by devfs(5).
own This action changes the ownership of devname. The arg parameter must be in the form of an owner:group pair, in the same format used
by chown(8).
perm This action changes the permissions of devname. The arg parameter must be a mode as explained in chmod(1).
FILES
/etc/devfs.conf
/usr/share/examples/etc/devfs.conf
EXAMPLES
To create a /dev/cdrom link that points to the first SCSI(4) CD-ROM, the following may be added to devfs.conf:
link cd0 cdrom
Similarly, to link /dev/cdrom to the first ATAPI CD-ROM device, the following action may be used:
link acd0 cdrom
To set the owner of a device, the own action may be specified:
own cd0 root:cdrom
To set the permissions of a device, a perm action should be used:
perm cd0 0660
