OK, I was writing too close to midnight. What I had was one Group on
one 200GB drive, and two Volumes. 2GB swap, and 80GB data. The rest
was unused. There was an Ext3 file system on the 80GB data Volume.
After the mentioned power failure, the ext3 file system was in such shape
that e2fsck could not fix it in several passes. Unfortunately for
the sake of further troubleshooting, I gave up on it and did not write
down the exact e2fsck messages. But they were of the general type
"could not create node". Hundreds of messages, distributed in disk
address space giving me the impression that there was one for each LVM
segment.
I probably should have looked for LVM repair or validation tools, but
just gave up on the whole thing instead.
