Since today 7 AM, I read a huge amount of "read-only" error messages in the syslog and cannot do anything on the root system. I installed Armbian 21.08.1 onto /dev/mmcblk2p1, with just 24% of the space in use. Rebooting doesn't help and the system is basically unable to do any operation like getting updates or creating files. Any idea what's going on? Is the built-in storage dying?

I have a Ubuntu Server 18.04 with postfix installed and configure it the same way as I did on my Helios64 running Armbian 21.02.3 Focal. Last week, one of my older drives died in the Helios, but I didn't get an email about this. My Ubuntu Server 18.04 will send me mails as soon as there's an issue in the SMART values from the drive. I didn't had to configure anything to do that apart from postfix. I can send a test mail from both my Ubuntu Server 18.04 and my Helios64 Armbian and receive both. Any idea what the reason is that my Ubuntu Server 18.04 is sending me those emails by default and how I could enable this on my Helios64?

@Werner @gprovost I just installed the Armbian update to v20.11.4. How do I find out if it fixes the issue with the Rockchip?

While I didn't experience reboots, I had freezes after prolonged periods of writing to HDD via SFTP. Support told me to do this and that fixed it: https://forum.armbian.com/topic/16440-armbian-20111-focal-freezes/?do=findComment&comment=115786 Maybe this helps you, too.

Support told me to do the following: Run `armbian-config`, go to -> System -> CPU And set: Minimum CPU speed = 1200000 Maximum CPU speed = 1200000 CPU governor = performance I'm now writing to my HDD via SFTP for more than 1.5 days without an issue, so that seemed to solve it.

Thanks for your response. I'm only allowed to answer after 24 hours, for some reason. I disabled the log2ram but the log files are still not showing anything interesting. Crash happened on 15th of December around 16:00 and restart was around 19:50. Here's the relevant section from /var/log/syslog: /var/log/kern.log: Nothing interesting found in /var/log/dmesg. Do you mean connecting via COM/USB? I lose connection if it happens, but I can try. Anything else I can do to investigate this? Do you think my device is broken?

When I'm connected via COM/PuTTY, this is what happens when the system freezes while i monitored via iotop: After that, I cannot send any commands via COM, so the system is definitely freezing. It's also happening when copying to any drive and it's also happening when there's less drives connected. Any idea what this instability is caused by?

I'm using Armbian 20.11.1 Focal (5.9.11-rockchip64) on my Helios64. When there's heavier load via ethernet (SFTP to a SATA Ultrastar 12TB disk) for something like more than an hour, the entire system will freeze. Not sure if it actually does freeze but I lose all SSH connections and cannot connect anymore via SSH unless I restart the Helios64. Happened today 4 times and it's totally reproducible. Haven't tested another drive yet. What makes this difficult to debug is that under /var/log/syslog or kern.log or faillog nothing relevant is being written as to in what state the device is. Is this a known issue? How can I find out what the problem is?
