My server did this about a week ago too. I figure its probably a plugin or something.

I can't get to the web UI for Unraid.

There is also one docker image that is down (no webUI, no other responses). The other images seem to be working fine.

I know I can hard-reboot the box, by physically pressing the power button, but I'm wondering if there's anything else I could/should do instead?

Another way into the machine? To at least do an Unraid-commanded reboot instead of pressing the power button?

Also, once it's back up, where if anywhere can I look to help narrow down wtf happened?

Thanks everyone.

Do you have an attached monitor and keyboard?

I do now!

See if you can get the diagnostics, or the syslog at least

cp /var/log/syslog /boot/syslog.txt

If the flash drive is not shared over SMB and you can still access other shares, copy there instead.

Monitor shows an endless list of the following message:

crond[1942]: exit status 126 from user root /usr/local/emhttp/plugins/dynamix/scripts/monitor &> /dev/null

With one or two of these:

crond[2967834]: unable to exac /usr/sbin/sendmail: cron output for user root /usr/bin/run-parts /etc/cron.hourly 1> /dev/null to /dev/null

I tried to log in and got this:

Last login: (timestamp) on tty1

-bash: /usr/share/bash-completion/bash-completion: Input/Output error

Unraid Server OS version: 7.2.3

IPV4 Address: (ip address)

IPv6 Address: not set

and then it just prompts for the login again.

I'm going to hard reboot it and then look for those diags and logs.

EDIT: I see that hard rebooting has cleared the syslog file. I should have expected this. I did some reading and turned on the syslog server, so hopefully if/when this happens again, I can go get the log after the fact.
