I added a zfs pool today using 4 disk in a raidz1 but when i rebooted my server is now stuck at boot with an blinking prompt. It does not even make it to grub. I may have updated the server, but I thought they were just some minor upgrades. I have upgraded in the past and never had any issues. I think the issue has to do with creating a zfs pool and a dataset. but I did not do anything to the disk the os is installed on. I am confused with why it is doing this.
