- You can NOT snapshot a VOB without first locking the VOB to make
sure it is consistent.
Will> Yep; the way we used to do it: (a) lock the VOB, (b) copy over Will> the non-storage-pool VOB stuff to the filer [so you've got all Will> the VOB stuff in "one place"]; (c) snapshot; (d) unlock the VOB; Will> (e) take a copy of the snapshot at your leisure; (f) delete the Will> snapshot.
The problem with us doing this is that we're also doing builds at night when we're backing up the VOBs, so locking them for any real length of time is out of the question for us. Instead we do:
1. lock vob 2. break vob mirror 3. unlock vob. 4. mount the quiet half of the mirror 5. back up the quiet half 6. unmount 7. rebuild the mirror.
Not ideal, but until we get the VxFS filesystem and it's snapshot ability, I can't do better. And of course this isn't using toasters for storage, so it's a bit off topic.

Why can't you share it with the rest of the world?
