zpool upgrade and lz4 compression.

[Vusa Moyo]

To elaborate, 

Server 1 

[root at qaMKSYSB01 /mksysb/qasediap01]# zfs set compression=lz4 mksysb/qasediap01
[root at qaMKSYSB01 /mksysb/qasediap01]# 




Server 2 

[root at qaMKSYSB02 /var/db]# zfs set compression=lz4 mksysb/qaiam05
cannot set property for 'mksysb/qaiam05': 'compression' must be one of 'on | off | lzjb | gzip | gzip-[1-9] | zle'
[root at qaMKSYSB02 /var/db]#
