I had the same thing happen a little while ago, and I ended up losing
data. I tried to recover it, but it was toast (and I wasn't spending
big $$ for a professional rescue service just to get my recorded TV
back!). In the end, the best I could do was similar to your "C" option
-- I mounted it read only with this:
mount -o ro,norecovery /path/to/lvm/device /new/mount/point
(replace directories paths, of course). I was able to get everything
except seven or eight programs, but it was still a real pain. Also, the
copy process was *really* slow (literally days) because the drive was on
its last legs. I was able to find out which programs didn't make it and
just re-scheduled them for later.
This really soured me on LVM ... the array had been running for almost 4
years though, so I wasn't that surprised. After that, I just started
manually moving recordings onto other drives and soft-linking them into
the recordings directory. I do plan to take advantage of the storage
groups someday though ... when I get some time ...
