Failed to delete boot environment

[Nasb Klamb]

I'm trying to delete old boot environments, and one of them refuses to be deleted. I'm on 11.2-U4.1 and have tried both the new and legacy web interfaces. Both of them get an HTTP response payload: "Failed to delete Boot Environment." and nothing else.

Edit: I found log messages:

May 11 13:05:33 alpha uwsgi: [freenasOS.Update:105] cannot destroy 'freenas-boot/ROOT/11.2-U3': filesystem has dependent clones
May 11 13:05:33 alpha uwsgi: [freenasOS.Update:105] use '-R' to destroy the following datasets:
May 11 13:05:33 alpha uwsgi: [freenasOS.Update:105] freenas-boot/ROOT/11.2-U2.1
May 11 13:05:33 alpha uwsgi: [freenasOS.Update:105] freenas-boot/ROOT/default
May 11 13:05:33 alpha uwsgi: [freenasOS.Update:105] freenas-boot/ROOT/Initial-Install

I had renamed the boot environment to 11.2-U3-BROKEN, but I'm guessing this is only an external name and the logs still think it is 11.2-U3. So I'm now reluctant to delete the default and Initial-Install boot entries. Advice?

filesystem has dependent clones

The error explains the problem. There are clones that depend on the image. You need to delete the clones first.

I deleted the clones and then the broken boot environment.

What I learned:
1. The logs in /var/log/messages indicate the dependencies -- the UI gives no useful feedback
2. The "default" and "Initial-install" boot environments can be deleted as long as they are not "Now" or "Reboot"
