I need a cluster filesystem for an iSCSI device. The problem is that the servers to which it is connected generate datafiles which must be read by every other servers. Except for the writing and deleting of such files, I do not need a full locking scheme like in OCFS2 or GFS2.

So, can I use a distributed lock manager (DLM) on top of an ext3 filesystem or must I use only specialized filesystem ?
