Why has the zpool command changed?
Changes to the zpool command in Nevada, builds 125-129, are as follows: • Device name changes due to integration of 6574286 (removing a slog doesn’t work) – This change adds a top-level virtual device name to support device removal operations. The top-level device name is constructed by using the logical name (mirror, raidz2, and so on) and appends a unique numeric number. The zpool status and zpool import commands now display configuration information using this new naming convention. For example, the following configuration contains two top-level virtual devices named mirror-0 and mirror-1.
