Solaris ZFS Administration Guide

Determining if Problems Exist in a ZFS Storage Pool

The easiest way to determine if any known problems exist on the system is to use the zpool status -x command. This command describes only pools exhibiting problems. If no bad pools exist on the system, then the command displays a simple message, as follows:

# zpool status -x
all pools are healthy

Without the -x flag, the command displays the complete status for all pools (or the requested pool, if specified on the command line), even if the pools are otherwise healthy.

For more information about command-line options to the zpool status command, see Querying ZFS Storage Pool Status.
