Oracle Solaris ZFS Administration Guide

New ZFS System Process

Oracle Solaris 10 9/10 Release: In this Solaris release, each ZFS storage pool has an associated process, zpool-poolname. The threads in this process are the pool's I/O processing threads to handle I/O tasks, such as compression and checksumming, that are associated with the pool. The purpose of this process is to provide visibility into each storage pool's CPU utilization. Information about these process can be reviewed by using the ps and prstat commands. These processes are only available in the global zone. For more information, see SDC(7).
