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. -- Stephan Wiesand DESY -DV- Platanenenallee 6 15738 Zeuthen, Germany
