 you have to run the program on a client that mounted the zfs volume via nfs.
 it fails no matter what pool version, either 6 or 13
 btw, it works fine if the server is solaris/v13
 
 but just to answer your questions, dev is the server host
 
 dev> zfs upgrade
 This system is currently running ZFS filesystem version 3.
 
 All filesystems are formatted with the current version.
 dev> zpool upgrade
 This system is currently running ZFS pool version 13.
 
 All pools are formatted using this version.
