During pfSense boot: syslogd “operation not supported by device” messages

Posted by jpluimers on 2020/09/25

If during a pfSense reboot you get one or more messages from syslog about “operation not supported by device” on various log files, then they are likely corrupt.

I had this when a pfSense 2.4.x RELEASE version VM was accidentally power-cycled during initial setup.

The solution was to choose option 8 (Shell), then in the /var/log directory, remove all files with extension .log, then reboot.

Now the messages were gone and the web UI showed logs. clog /var/log/system.log showed content as well.
