Hi,
I turned on my main home server after a few weeks absence, and got
smoke from its power supply. Fortunately, I have a backup system, which
does work; both are running Debian 10, so I swapped use to that machine.
and am able to work with that, but some of the files and settings are a
bit out of date.
I decided to move the disk from the broken machine to the backup, but on
booting I'm dropped into a grub screen saying disk id <blablabla> not
found. Not entirely surprising perhaps.
So, how do I get it to recognize, and boot from the old disK.
Cheers, Tony
Please provide a hardware inventory for each computer.
For each disk drive, please describe the purpose of the drive.
Please tell us how each computer is booted, what services are provided,
and what data is stored.
Prior to the disaster, please tell us about your disaster preparedness
measures. Were backups, archives, images, etc., up-to-date?
Since the disaster, where is your live data? Have your disaster
preparedness measures changed? Are your backups, archives, images,
etc., up-to-date?
Have you repaired the main home server? When the power supply failed,
did anything else fail?
Suggestions:
1. Install Debian onto a high quality USB 3.0 flash drive, to use for
maintenance and troubleshooting.
2. Buy a hardware power supply tester.
3. Buy external drive adapters corresponding to whatever internal
drives you use -- so that you can remove internal drives, connect them
to the adapters, and access them using another computer.
4. Do not be afraid to "throw money at the problem" -- e.g. maintain an
inventory of spare parts and computers. The last time I lost data was
when I decided not to buy big, new, backup HDD's for a data migration.
