Re: [Linux-cluster] Split-brain with DRBD active-active + RHCS



Hi Mark,

Yes, clustered file system is mandatory. Even with gfs(2) DRBD will
not recover by itself from a split brain. I think specific options are
needed in drbd.conf "after-sb-0pri after-sb-1pri after-sb-2pri", but
don't know what the exact ones are.

Best regards!
