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 ?

MySQL's unique architecture allows for plugin storage engines.

I have a new external disk and just made an ext3 partition on it. I'm wondering what's the best way to set permissions on it (so that it's rw for certain users). I guess I could chmod ... /dev/sdb1 but I was thinking of a more dynamic way (kind of like uid= and gid= options for vfat and such). >>> More
