More generally, can LVM perform RAID1-style mirroring with only

You should be able to force LVM to create a log device on one of your
two devices (--alloc anywhere)

So what happens if the disk containing the log dies?  Does LVM
keep running (presenting the logical volume implemented on the
physical volumes on the still-working disk)?

(And what happens at reboot time (with the failed disk still in
place)?)

Thanks,
