I have DSM 107 with latest firmware 3.0. It is connected to UPS 800VA, so is protected against power failure.
Today when I came to home, I want to do something on it, but DSM not respond. ICMP ping is working, but I can't connect to it over HTTP or SSH. So I restarted it, and DSM take new IP from DHCP and in Synology Assistant I can see it as Not installed.
I know how to backup my data, but I want to provide logs for you. Where I can find it ? What type of logs do you need ?
