Hi,
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

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.
Thanks,
