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.

A side effect was that no logs showed in the web UI either, nor would clog on any file in the /var/log directory.

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

Delphi – The use of AlignAttribute: indicate the alignment of a field

It forces the element it annotates to be aligned like specified – valid values are the same as for $A (1, 2, 4, 8, 16)


  TMyRecordA = record
    x: Integer;
    y: Int64;

  TMyRecordB = record
    x: Integer;
    y: Int64;
  a: TMyRecordA;
  b: TMyRecordB;
  offset: Integer;
  offset := PByte(@a.y) - PByte(@a);
  offset := PByte(@b.y) - PByte(@b);

this will output:
