Subject: clustered MD - beyond RAID1
Date: Fri, 2 Dec 2016 11:12:52 -0700 [thread overview]
Message-ID: <CAB9NSeV2A+BZzUbzj516e24CL05k6zF6tgZ+vpNptSO30ipyug@mail.gmail.com> (raw)
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.
