Lon and the other gurus - have you guys ever seen an ext3 volume get mounted on multiple cluster nodes at the same time WITHOUT a split brain? No fencing, no errors logged, no network issues, etc.. I even ran clustat and both nodes (let's say B and C ) even said that the single node I thought was up was in control (B). I saw this with virtual ip's in my testing but then encountered this during deployment that then quickly corrupted the volume and brought the project to a halt.. No worries if not - I have support involved already, just curious your input as you guys seem to know this stuff inside and out!
Sure, that works. The only problem is that if both nodes write to the same files at the same time (including meta data), you'll end up with a corrupted file system. But if both machines are mounting the FS read-only (in which case you might as well use ext2), then there's no problem with that.
