Okay, so after some test with dedup on snv_134. I decided we can not to use dedup feature for the time being.
While unable to destroy a dedupped file system. I decided to migrate the file system to another pool then destroy the pool. (see below) http://opensolaris.org/jive/thread.jspa?threadID=128532&tstart=75 http://opensolaris.org/jive/thread.jspa?threadID=128620&tstart=60 Now here is my problem. I did a snapshot of the file system I want to migrate. I did a send and receive of the file system zfs send tank/export/projects/project1...@today | zfs receive -d mpool but the file system end up smaller than the original file system without the dedup turn on. How is this possible? Can someone explain. I am not able to trust the data now until I can verify the data are identical.
