Right, if you can't unmount there are several options ... we have a rescue mode on CD-1, the DVD, or the Single Server CD ... also we have the live CD.
The OS you boot to needs LVM2 and all the EXT3 tools ... personally I recommend the LiveCD ... that was one of it's main purposes. It is much more full featured than the rescue mode on the other CDs.
What would be nice, if it already isn't in the live cd, would be a command or binary to look for and mount the existing installations like the rescue mode does. If this is already there, then pardon me, as I haven't seen it. A lot of us know how to walk through and do this, but many people do not.
While the LiveCD does not mount the devices in /mnt/sysimage ... it can automount all partitions.
If you start it with the command:
linux automount
You end up with all your partitions mounted in /mnt/ by their name.
But does that mount LV's in LVM? Or do you still need to use LVM commands to activate LV's?
It will automount LV's if you do automount ... for example ... /mnt/dm-0 was my root filesystem when I booted up and vgdisplay and lvdisplay show all the items there.
you can unmount and remount other ways if you want.
I also had sda1 as my boot partition ... that showed up as /mnt/sda1 ... it was not mounted as /mnt/dm-0/boot ... so if you want to mount items like that, you will have to do it manually.
Just having the accesibility is great! I always have the regular rescue mode for when I need chrooted /mnt/sysimage access.
