Description Jonathan Earl Brassow 2006-05-16 22:32:19 UTC 
Take a snapshot of an in-sync mirror and do an 'lvs'.  The mirror copy% will be
0.  Doing a 'dmsetup status', however, shows that the mirror is, in fact, in-sync.

Patch to fix problem

Check if mirror is under an origin.
Comment 2 Alasdair Kergon 2006-05-24 13:35:56 UTC 
Other parts of the code also don't support snapshots of mirrors yet.

Fixing lvcreate instead to prevent them from being created in the first place.
