Excuse me for being late to the party on this subject, but is the idea of clustered RAID5/6 alive or dead? I have a need for such a feature. I'm in development on SAS JBODs with large drive counts, 60 and 90 drives per JBOD. We would like to support multi-host connectivity in an active/active fashion with MD RAID60. This clustered MD RAID can and should be a nice alternative to HW RAID solutions like LSI/Avago "Syncro" MegaRAID. I currently have the hardware and time to help develop and test the clustered RAID5/6. I just finished up building a test cluster of 2 nodes with the cluster-md RAID1. Worked fine with gfs2 on top. My current real job is firmware on these SAS JBODS. I have many years of Linux experience and have developed (years ago) some kernel modules for a custom FPGA based PCIe cards. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
