Hello there fellow TrueNASers,
I updated to the latest version of EE (25.04.2.6) a few days ago. After the reboot, I noticed a notification telling that boot-pool was getting overcrowded (“Space usage for pool ‘boot-pool’ is 90%”). I just ran zfs list: it looks like all previous versions are still there, eating space (cf. below output). Question is, I suppose: do I need to manage this, or would it get somehow automagically managed? If I should manage this, what should I do? I sure don’t want to blow up the system, do I?
Here is the output:
$ sudo zfs list | grep boot-pool
