Unraid server shutting down randomly !! Sever name automatically changed to default tower

[drmetro]

My unraid server is shutting down randomly, it happened 3 times today …. Even the name of my server has got automatically changed to default Tower .

after the restart it takes more than usual time to mount the disks and the docker service doesn’t start on its own , i have to manually start it from settings > docker .

 I have checked the hardware there is no issue. This thing is weird why is it happening and how automatically my server name changed to tower . 

im completely new to this please can someone help 

thanks

If the server really shuts down, vs crashing or hanging, that's almost always a hardware issue, or power problem.

The server name resetting to default suggests that Unraid was unable to read some configuration information from the flash drive.   You might want to try plugging the flash drive into a pc/Mac to check it is ok.

How do i check if the unraid configuration is ok ? Im noob at this could you please guide ?

 It could be worth enabling the syslog server to get a log that survives a reboot so we can see what happened prior to the reboot. The mirror to flash option is the easiest to set up, but if you are worried about excessive wear on the flash drive you can put your server’s address into the Remote Server field.
