[Bug 1281202] Re: weekly fstrim cron job reports errors

Just found that the problem is possibly not originating from fstrim.
As hdparm -I /dev/sda reports the error
 SG_IO: bad/missing sense data, sb[]:  70 00 05 00 ...  I suppose fstrim is just passing the error.

I doubt that it is a real error as my ubunt is a VM with vmfs disk.
Thus fstrim should be silent about the missing sense data at least when the disk has no TRIM capability at all.

Title:
  weekly fstrim cron job reports errors

Status in “util-linux” package in Ubuntu:
  Confirmed

Bug description:
  Every week I get an email from cron with error output from the
  /etc/cron.weekly/fstrim job:

  /etc/cron.weekly/fstrim:
   HDIO_DRIVE_CMD(identify) failed: Invalid argument
  device /dev/md0 is not an Intel or Samsung drive
  SG_IO: bad/missing sense data, sb[]:  70 00 02 00 00 00 00 0a 00 00 00 00 3a 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
  SG_IO: bad/missing sense data, sb[]:  70 00 02 00 00 00 00 0a 00 00 00 00 3a 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
  device /dev/sdf1 is not an Intel or Samsung drive

  It's true that those block devices are not Intel nor Samsung SSDs
  (though /dev/sdc is an Intel SSD), but I don't think fstrim-all should
  be printing a warning in this case.
