So I had Docker disabled and I don't use VM so that was already disabled. in safe mode array stopped and started fine and when I booted into normal mode same. As soon as I re enabled Docker and my dockers started the issue happened again. what seem to have fixed it is I had in directory as the Docker data-root, when I changed it to or back to xfs vdisk and reinstalled all of my dockers with the appdata too with my backup the issue no longer happens.
