Description Steve Tyler 2010-02-28 15:23:48 UTC 
Description of problem:
The live installer deactivates volume groups, making it impossible to mount logical volumes from the "Places:Removable Media" menu.

Version-Release number of selected component (if applicable):
http://serverbeach1.fedoraproject.org/pub/alt/stage/13-Alpha.RC4/F13-Alpha-x86_64-Live/F13-Alpha-x86_64-Live.iso

How reproducible:
Always.

Steps to Reproduce:
1. Boot from live installer (I used a USB stick) on a system having previously configured logical volumes.
2. From the "Places:Removable Media" menu mount a logical volume, say lv_foo.
3. Start the installer and immediately exit.
  
Actual results:
An lv_foo icon appears on the desktop when mounted,
but when the installer starts, the icon disappears.
Further, lv_foo cannot be remounted.
An error message is displayed:
  Unable to mount lv_foo
  Underlying device missing

Expected results:
Logical volume groups that were active when the live image was booted,
remain active after the installer exits.
Mounted volumes remain mounted.

Additional info:
Bug 568460 also concerns logical volumes.
Comment 1 Steve Tyler 2010-02-28 20:18:15 UTC 
A work-around is to reactivate the volume group with:
"Applications:System Tools:Disk Utility".

Or from the command line:
# vgchange -a y vg_walnut

Verify with:
# lvs
or
# ls /dev/mapper


The net installer ISO also deactivates logical volumes. While this doesn't appear to affect end-users, it does make debugging and testing harder, because the LVs may be needed to save screenshots or log files. They may also contain the bugzilla password.

Further, the LVM commands (e.g. vgchange) are not available.

See: Bug 569071, Comment 2.
Comment 2 Hans de Goede 2010-03-01 09:55:42 UTC 
Deactivating logical volumes before starting the installer is necessary, as people may want to re-partition their disk. So we must unmount and de-activate.

As for the desktop still allowing you to try to re-mount lv_foo, even though the
VG was de-activated that is a bug of the desktop, please file a bug against
nautilus for that.

Thanks. I didn't think of it that way. :-)
