[SATLUG] Cluster File System?

[John Pappas]

We set up a 2 node Win2K cluster to attempt this same thing.  We used
Kayo from SanBolic (since discontinued in favor of an actual shared fs
called Melio FS) to share the NTFS volume.  It worked fine, but the
initial setup was tricky (I suspect this is the case with most shared
FS), as each box had to be loaded WITHOUT connectivity to the SAN.  Once
the software was loaded, the FC was plugged back in and all was cooking.
This type of solution is basically a lock control layer placed on top of
NTFS.  A true "shared file system" handles locking internally.

Before I left my last position, we were looking into CXFS from SGI and
GFS from RedHat, but I did not have the opportunity to play with either
personally.

As an aside, Some research that I did indicated that both of these have
scalability issues, as the control is coordinated serially and
atomically through one server process, so performance is 'artificially'
limited at high I/O rates.

Let me know what you find out!
