Applies to:

Solaris Operating System - Version 10 6/06 U2 to 11.1 [Release 10.0 to 11.0]
Information in this document applies to any platform.

Symptoms

Exporting a zpool from a Solaris system can take an extended period of time, especially on systems with large amounts of memory available to the ZFS ARC.  Examining the process's thread stack using mdb shows it blocking within arc_flush() from spa_unload().
