Hi Alan and all,
Hi Alan,
Thank you for your comment.
This program isn't considered as a quorum module for now.
It was developed as RA, I mean, it provides an independent function without
some effects to Heartbeat's internal behavior.
since we don't have familiar with a quorum module,
what are the requirements for it?
We have no problem with improving it, but it's not known exactly how we
should do.
For example, SF-EX accesses to disk periodically by the active node to
keep holding lock.
We think quorum module can not operate this. Are we wrong?

Hello, all.
We wrote a Shared Disk File EXclusiveness Control Program, called
"SF-EX" for short, could prevent a destruction of data on
shared disk file system due to Split-Brain.
This program consists of CUI commands written in the C and RA,
the former is used for managing and monitoring shared disk status
and the latter is the same as other common RAs.
We tested this program on IBM and HP platform, and we confirmed
all functions worked well.
Our test environment is listed below:
Software:
OS :RHEL4 ES Update5(kernel2.6.9-55.ELsmp)
HB2:heartbeat-2.1.2-2
Hardware:
IBM platform:
Server : System x3650
Shared disk: DS 4700 (FC)
HP platform:
Server : DL380G5
Shared disk: MSA500G2 (SCSI)
How to install and configuration are described in README.
If you are interested in this program, please try it and
let me know your comments.
Your suggestions on how to improve are really appreciated.
This program would be even more useful if it were available as a quorum
module. Have you thought about making it a quorum module?
Thanks!
