I was using 8.1-RELEASE and upgraded to 8.2-RELEASE to make see if it improved. [root@san2 ~]# zpool upgrade This system is currently running ZFS pool version 15. All pools are formatted using this version. [root@san2 ~]# zfs upgrade This system is currently running ZFS filesystem version 4. All filesystems are formatted with the current version. [root@san2 ~]# uname -a FreeBSD san2.a2hosting.com 8.2-RELEASE FreeBSD 8.2-RELEASE #0: Thu Feb 17 02:41:51 UTC 2011 r...@mason.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 Little more detail. The zvol that is the source of the clone is an image I use for all my filesystems. I was able to create one clone and promote it. However, when I tried to do it a second time I received that error. Can you only have 1 promoted clone per source? I don't really need to promote them. I just wanted to be able to delete the source image once the box was full. If it has a ton of associated clones it'll be stuck there forever.
