Hello Dennis,
we had similar situation as yours with medium-sized databases on Solaris
servers using VCS.
For new environment we created active/passive failover clusters using
Oracle Clusterware on Linux with OCFS2 used for shared storage.
(knocking on wood) We are running clusters now over a year without any
problems.
Just after initial installation we had some storage problems cause of bad
drivers and lousy FC cables/ports, but after we fixed that everything works
without any errors.
Local disks are used for binaries and database files are on OCFS2 mounts.
For managing resources we're using custom scripts.
I've heard lots of bad stuff about OCFS2 but I think the most problems
happen if you use it to store large number of files.
It is not very flexible system as ASM and maybe it has slightly poorer
performance then ASM but for us it serves its purpose.
All my doubts were pointed to OCFS2 and I've spent over a month performing
various stress/load/failover tests.
OCFS2 successfully survived all of them.
Are there better solutions then this, probably, but even on the most
expensive solutions you could expect bugs and problems.
Biggest benefit of this solution is cost-effectiveness.
I hope everything will work fine in next years as it worked till now :-)
Regards,
Marko
