Description Skippy 2011-03-11 10:32:25 UTC

Description of problem:
USB drive is duplicated each time the system resumes from suspend, which results in multiple devices and duplicate partitions mounting points.


How reproducible:
Allways.


Steps to Reproduce:
1. Plug in an USB drive.
2. Go to suspend.
3. Resume from suspend.
 

Actual results:
Although the USB drive partitions are still mounted from before going to suspend, the drive is detected as a new device (/dev/sdb, then sdc, then sdd, etc.).  This results in multiple mounting of partitions.


Expected results:
The system should know that the drive has already been detected and partitions should only be mounted once.


Additional info:
Maybe is it related : in my case, the mounting point of the partitions are specified in /etc/fstab.  When resuming from suspend, the system fails to mount them because of insufficient permissions, then mounts them automatically after a few seconds.

This is certainly not right, device should occupy the same device file. Though I understand there might be a race somewhere and suspend/plug-out event gets delayed somehow.

What about the old mount, does it still exist? Can you list files there? Or is it forcibly unmounted?

Automounting is correct in this case as long as new device is detected. Suggesting looking at the kernel <--> udev stack.

Comment 2 Skippy 2011-03-15 10:25:19 UTC

Indeed previous device files have been deleted :
$ ls /dev/sd*
/dev/sda  /dev/sda1  /dev/sda2  /dev/sda3  /dev/sda4  /dev/sda5  /dev/sdi  /dev/sdi1  /dev/sdi2  /dev/sdi3  /dev/sdi4  /dev/sdi5  /dev/sdi6

But they still appear in df :

And they cannot be unmount through nautilus, because "umount: it seems /mount/point is mounted multiple times".

Mounting points are the same, so yes, files can be listed.

Please note that making changes to the filesystem can be dangerous.

Could you please run `udevadm monitor` and attach the output here after a single suspend/resume cycle so that we could identify what's going on?

Comment 4 Skippy 2011-03-15 10:49:04 UTC

$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

Sorry, I didn't noticed it was that long, I should have attached it…

Comment 6 Harald Hoyer 2011-03-15 11:23:03 UTC

this is the kernel... not udev

Comment 7 Tomáš Bžatek 2011-03-15 14:39:14 UTC

Thanks for the output. If your time when a machine was suspended was only five seconds, then it looks sane. Except of kernel attaching usb mass storage device with a different device file.

Perhaps the following event causes the issue:

as long as it happened after resume.

Indeed I went to suspend solely for the purpose of obtaining the output, so it should not have lasted more than a few seconds.  I can wait a bit longer if needed.

Comment 9 Fedora End Of Life 2012-08-16 13:46:49 UTC

This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
