Looks like I am hitting the same issue now from the earlier post that you responded. http://opensolaris.org/jive/thread.jspa?threadID=128532&tstart=15
Continue my test migration with the dedup=off and synced couple more file systems. I decided the merge two of the file systems together by copying the one file system into another one. Then when I try to delete directories in the 1st file system, the whole system hung. The file system was done with dedup turn on half way through the sync then turned off since I wasn't able to finish the initial sync with dedup turned on. But now looks like there is no way to get rid of dedup file system safely. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
