I am having an issue where my true NAS scale 23 box will not boot, it is stuck at a grub rescue screen saying “error: symbol ‘grub_disk_native_sectors’ not found”.
Two things have happened recently:
-
I upgraded from scale 22 to 23. This was completely successful and has been running for probably about a month. I have not rebooted in this time at all. I also did not do anything that would trigger a feature flag upgrade on any of my pools. I was giving it some stable time before going to version 24.
-
a couple of weeks ago one of my boot disks died. It was in a two disc boot pool mirror and I replaced the disc using the UI (system → boot → find disk → replace) And as far as I knew it was successful.
Earlier today I got an alert from my monitoring system but the agent was unavailable on the NAS. Following that, all of my virtual machines whose storage is backed by eye scuzzy on the all of my virtual machines whose storage is backed by iScsi on the NAS stopped responding. The web UI for the NAS was frozen at something like “waiting to connect to the controller”. I shut down my hypervisors and rebooted the NAS, And since it came up it is going directly to the grub error screen and I am stuck.
Any help is appreciated. I’m having difficulty searching as I’m stuck being just on my phone right now but I am finding a lot of people with issues during the system install but not issues like this on a running system.
