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?
After I booted up on the CentOS 4.4 live CD, the LV's where both there, I just needed to mount them. And BTW, I tried the snapshot thing, it worked flawlessly. I tarred a backup then removed the LV of the snapshot. Now my next step is to see if I can actually restore the whole system on my test box. I also tarred the hda1 which is mounted as /boot. If this all goes well, I won't ever have to bring the system down for DD backups anymore.
