Anyone made any lvm boot floppies
-----BEGIN PGP SIGNED MESSAGE-----
I have made extensive use on lvm on my system. All filesystems apart from
root (this includes a separate /var and /usr) are lvm logical partitions).
I backup root (and other things) disk to disk on a daily basis to one of these
partitions so that I can simply recover from failure.
A couple of days ago a disk fault wiped out the superblock on my root
partition. That was when I discovered the flaw in my approach.
My boot floppies could not open the lvm volumes - so I could not get at the
backup to restore my root.
In the end I had to re-install debian from scratch (somewhat difficult as the
root partition is too small for a full install (remember that /usr and /var
are on a lvm volume normally but could not use these during this install).
Then dist-upgrade it to sid (otherwise I have libc6 compatibility problems)
before overwriting root whilst it was running. It took me several evenings
work to get it right.
Before I put my back into creating boot floppies with lvm support (although it
appears easy, I have tried it before and never fully succeeded in getting
something small enough) - has anyone done this already?
