Good day raiders,
I have a question on md that I cannot find (up to date) answer to.
We use SuperMicro server with 16 shared disks on a shared backplane
between two motherboards, running up to date CentOS7.
If I create an array on one node, the other node can detect it. I put
GFS2 on top of the array so both system can share the filesystem, but I
want to know if md raid is safe to be used in this way with possibly 2
active/active nodes changing the metadata at the same time. I've
disabled raid-check cron job on one node so they don't both resync the
drives weekly, but I suspect there's a lot more to it than that.
If it's not possible, then alternatively some advice on strategy to have
a large active/active shared disk/filesystem would also be welcome.
Best regards
