[Bug 1131715] Re: fstrim fails with FITRIM ioctl failed: Operation not supported

[Phillip Susi]

So you are saying it works in 13.04, but not in 12.10?  Then it has
already been fixed.


** Package changed: util-linux (Ubuntu) => hdparm (Ubuntu)

Title:
  fstrim fails with FITRIM ioctl failed: Operation not supported

Status in “hdparm” package in Ubuntu:
  Invalid

Bug description:
  The problem is that `fstrim -v /` fails, and `fstrim -v /home` does not, even though they both reside on the same physical disc.
  I did not have this issue on 13.04.

  /dev/sda is a SSD drive with TRIM support.
  # sudo hdparm -I /dev/sda | grep -i trim
             *    Data Set Management TRIM supported (limit 8 blocks)
             *    Deterministic read ZEROs after TRIM

  LVM is setup as such:
  # sudo pvs
    PV         VG   Fmt  Attr PSize   PFree 
    /dev/sda3  goku lvm2 a--  111.36g 23.47g
  # sudo lvs
    LV            VG   Attr     LSize  Pool Origin Data%  Move Log Copy%  Convert
    fresh_install goku swi-a-s- 10.00g      root    24.50                        
    home          goku -wi-ao-- 40.00g                                           
    root          goku owi-aos- 30.00g                                           
    swap          goku -wi-ao--  7.89g      

  /etc/fstab is also attached.

  I've also tried mounting goku/fresh_install and running fstrim on its mountpoint, it resulted in the same failure.
  Can the problem be that I have a snapshot of goku/root, again, it didn't matter on 13.04, under the same circumstances.

  Thanks!
