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.
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.
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.
