Hello: I kinda figured as much. So there's no way to just run part of it as read-only, run the checks on the other half, and then make the checked half the primary, after invalidating the read-only part and making the checked half copy over?

There's no way for DRBD to "merge" the fsck modifications on one node with the modifications the application makes on the other. And there _will_ be modifications (to the filesystem metadata) on the other node even if you mount there read-only. Florian -- : Florian G.
