So by "sharing" you mean mounting it on any of the servers, but never on more than one at a time? I'd expect this to work (but I admittedly don't know for sure) as long as it's really never ever mounted more than once. I think ext4 has no multiple mount protection. Any mistake may cause irreparable damage to the filesystem.

Sharing it using NFS is certainly the safer option.
