While playing with zones I encounter the following issue:
I cloned a zone via zfs clone, I then promoted the resulting file
system with 'zfs promote' (no good reasoning behind this decision)
After destroying a zone via vmadm destroy, the file system remains and
I'm unable to destroy it
The zone I cloned was based on Joyent image 842e6fa6-6e9b-11e5-8402-1b490459e334
The cloned zone is 235463b2-67b4-e224-bd17-b62b6cbf99eb
image 842e6fa6-6e9b-11e5-8402-1b490459e334 has since disappeared from
the list of available images
can someone make sense of what happened ?
thx
