[Bug 1044111] Re: blkid is hanging, or at least taking a long time to process partition statistics

 

I'm not sure whether to update this bug or:
- bug 155047 https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/155047
- bug 1029149 https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/1029149
as I suspect they are really all duplicates as they suffer the symptoms of this blkid bug.

I have been struggling to install LXLE 12.04.5 because of this bug.
gparted sits on "Scanning all devices..." for over 20 minutes every time
a change is made in gparted.

The problem is made worse by the Sony PCG-FX201 laptop not having any
option in the BIOS to say there is no floppy drive.  My workaround was
to put the floppy drive back in the laptop (one can either plug in the
floppy drive, a 2nd battery, or a weight-saver).

On installing the floppy drive, gparted continues and then works
normally.  (No floppy disk is required.)

It is caused by sudo blkid pausing for ages (appearing to hang) when
there is no floppy drive but responds instantly when it is installed.

I don't think blkid should hang when a drive is absent.

Title:
  blkid is hanging, or at least taking a long time to process partition
  statistics

Status in util-linux package in Ubuntu:
  Confirmed

Bug description:
  1. Lubuntu 12.10 i386 3.5.0-11-generic
  2. util-linux 2.20.1-5.1ubuntu1
  3. I expected sudo blkid to display partition stats. This bug is reference to bug #1029149 gparted never completing scanning all devices.
  4. I do not get the desired output from gparted or sudo blkid.

  The attached screenshot show the lack of results when using the sudo
  blkid command.
