dear experts,

I've been running MicroOS headless on multiple raspberry-pi 3bs with single
service (excl. system services) and/or as container host.

After some time, the devices no longer boots correctly, I am unable to ssh or
ping device. Since I didn't have extra monitor, I would do clean install of
MicroOS (with Combustion).

Doing this multiple times over the past months, I assumed maybe the SD cards
were corrupt so I used another SD card, unfortunately, after sometime same
happened.

I got my hands on dell inspiron tower, I installed MicroOS last week. This time
 disabling transactional-update.timer. Everything was working fine until I
enabled transactional-update.timer last week Wednesday, yesterday (Monday) I
attempted to ssh into machine and found it was no longer reachable.

I now have a monitor, plugged it in and am welcomed by blank screen (no login
prompt). After force rebooting machine I am welcomed with:
"Notice ��������� Hard drive self monitoring system has reported that a parameter has
exceeded its normal operating range. Dell recommends that you back up your data
regularly. A parameter out of range may or may not indicate a potential hard
drive problem
Press F2 to Resume"

Pressing F2, then waiting ... I eventually I see underscore cursor flashing and
nothing happens.

Where do I go from here?
I am unable to get to bootloader to log into device to check logs or to perform
btrfs rollback.


Kind regards,
Sam
