[Bug 525033] Re: During installation "Error informing the kernel about modifications to partition /dev/XXX -- Device or resource busy"

[pabouk]

Installation of Xubuntu 13.10 beta2, also observed with Xubuntu 13.10 beta1 and Ubuntu 13.10 beta1.
Installation on Asus Eeee PC 1000H.

After partitioning (default options) a popup with this text appears:

Error informing the kernel about modifications to partition /dev/sda1 --
Device or resource busy. This means Linux won't know about any changes
you made to /dev/sda1 until you reboot -- so you shouldn't mount it or
use it in any way before rebooting.

I tried to update the partition information manually without success:

# partprobe /dev/sda
Error: Error informing the kernel about modifications to partition /dev/sda1 -- Device or resource busy. This means Linux won't know about any changes you made to /dev/sda1 until you reboot -- so you shouldn't mount it or use it in any way before rebooting.
Error: Failed to add partition 1 (Device or resource busy)

I checked the status of /dev/sda:

# fuser -v /dev/sda
                     USER        PID ACCESS COMMAND
/dev/sda:    root         4051 F....      parted_server

So parted_server wrongly keeps /dev/sda open.

After pressing "Ignore" button in the popup the same message appears for /dev/sda2.
After pressing "Ignore" button again the following message appears:

The ext4 file system creation in partition #1 of SCSI1 (0,0,0) (sda)
failed.

Then the parted_server does not keep /dev/sda open any more and the
kernel partition table (/proc/partitions) is partially updated
(/dev/sda5). After running partprobe /dev/sda the kernel partition table
is updated completely (sda1, sda2, sda5).

After pressing OK in the last pop-up, the installer returns to the
"Installation type" window. After pressing "Install now" the
installation normally continues.

Title:
  During installation "Error informing the kernel about modifications to
  partition /dev/XXX -- Device or resource busy"

Status in GNU Parted - Partition manager:
  New
Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: ubiquity

  During installation a dialogue box appears with the following text:
   Error informing the kernel about modifications to partition /dev/sda2 -- Device or resource busy.  This means Linux won't know about any changes you made to /dev/sda2 until you reboot -- so you shouldn't mount it or use it in any way before rebooting.

  Screenshot attached.

  If I click Ignore, the installer pops up the same dialogue except
  referring to /dev/sda3.  The installer then continues after clicking
  Ignore on that one.

  Both /dev/sda2 and /dev/sda3 on my system are Unix partition types, which may shed some light:
   sda2: FreeBSD
   sda3: Solaris
