[4.4.2] Can't kill process while attempting to recover server

Moshpitius
in unRAID Server 4.4 [No new topics]

Featured Replies

I've tried to kill a locked process with no success.  I was copying a file to disk3 and it failed (this is common, I have another thread about exception/frozen timeouts).  Since the web interface is not accessible (just times out, even if I kill emhttp and restart it), I'd like to somehow recover my server remotely so that I can reboot cleanly.  How do I recover cleanly from a telnet session as root?  I've tried the powerdown script with a reboot but haven't had any success.  I was thinking this time I'd try to kill the smbd process and try again.

 

This is from a telnet session as root:
