November 9, 2025Nov 9 Hi.I have an odd issue that's been bugging me and I can't seem to find a solution to it.I was working on a virtual machine which for some reason completely froze Unraid's UI, but docker containers were still running. Only way to get around that was a complete shutdown. I ended up deleting the VM as well the libvirt.img file, however for some reason I can't delete the directory it was located in, which used to be a ZFS dataset which I converted with ZFS Master Plugin. Also tried to remove the domains share, but that didn't work either. System claims the directory isn't empty and if I attempt to delete it with Midnight Commander, is says the operation failed due to the directory being "busy".This might be related to a fix in Unraid 7.21 beta I just noticed that says "Fix: Remount dataset if 'ZFS destroy' fails because dataset is busy", but if someone has a solution to deal with this that would be appreciated.
