I now its OmniOs forum,question about Nexenta v4.0.4FP02.
Maybe issue is common to illumos,

Getting below error when trying to rollback zvol snapshot,zvol unshared before rollback operation,system rebooted but result was same.
 
any sugesttions?

zfs rollback -r OPOOL/DATA at snap-hourly-1-2016-02-16-130002

cannot rollback 'OPOOL/DATA': dataset is busy
 

Nexenta log:

My guess is that the volume you want to roll it back to is registred as an LU with stmf...is it? If so, you need to delete it first. But be aware, before you delete the LU you need to delete any view for that LU. Otherwise you get views "hanging in the air" which is difficult to get rid of.
