Disk Management Error: Unknown Filesystem

Hi,

I’ve been running StartOS for couple of months with following DIY setup:

ThinkPad X13 Yoga Gen 1: Intel Core i7, 16GB RAM with 2TB ScanDisk external portable SSD Hard Drive.

StartOS is the only operating system running on the machine. It ran good for 2-3 months. I had Knots full node, mempool, LND, Datum Gateway (5 Th/s miner), Vaultwarden, Alby Hub, noStrudel running.

One day, after coming home the server had stopped working and I got following Errors in my log:

start9 error
start9 error2040×1536 179 KB

StartOS Launch error:

Disk management error.

grub-probe-default: error: unknown filesystem.

I tried all the suggested options after restart: restart sevrer, system rebuild and repair drive with no success.

Unfortunately I don’t have a backup of my start9 system.

What would be the best course of action for me to:

  1. try to recover my Lightning Node and Vaultwarden information
  2. to get my server running without wiping data on my SSD
  3. to get server running with all data gone and SSD wiped

I truly appreciate any help!

Oof, though break man. So, little unclear what you want as 2 and 3 are in conflict

Restoration:
Lightning) I hope you have your seed phrase written down somewhere. If you don’t have that, you’re hosed
VaultWarden) Looks like you’re going to need a backup file of that as the db is encrypted even if you could recover it

Was the OS running from the external drive?
Do you have another computer that can read the drive?

This looks to me like a corruption on the internal drive, where StartOS is installed. You didn’t mention the internal drive. I assume it’s a small SSD, which is fine. Failure on this drive is a distinct possibility. Please confirm that I’m on the right track here.

I don’t have neither seed phrases backed up manually. I only have Vaultwarden admin token written up which probably doesnt help.

After removing external drive and booting up the machine it gives me additional StartOS disk not found error as well. Does it mean I flashed it on my external SSD partition? I wiped the original machine clean from any OS and data before installing StartOS. I thought installed the OS on the machine’s internal drive. The startOS logo and stuff pop up when I boot up the machine. This is what I get when booted up with no SSD:

start9 disk
start9 disk1600×1204 59.5 KB

Two of my other Ubuntu machines recognize the external SSD but neither of them are mounting it automatically. I could try manual mount but I’d like to hear your recommendations first.

Thank you so much !

I’m unclear as to why you are starting up the server with no drives attached.

I’m also unclear what drives and partitions you actually have.

–

StartOS uses two partitions, these are both on the same drive, or they are on separate drives, but there is always an OS partition and a Data partition.

Let’s assume the drive(s) you are using are not dead, and let’s assume your data partition is recoverable, do this:

  1. Flash a USB thumb drive, boot it, and select your OS partition following this guide:
    Start9 | StartOS (x86/ARM)

  2. Remove the USB, boot the server and follow this guide:
    Start9 | Use an Existing Data Drive
