I am Software Manager in Mantech, and testing drbd 9.
some problems are occurred. CASE 12 is one of them.
[CASE 12] 2 primary split-brain is not detected.
- Linux VM 2 nodes
- Linux drbd version 9.0.0
- 2 node's status is uptodate
node 1node 2drbdadm disconnect r0 drbdadm primary r0 copy files on
primary r0 copy files on node2
drbdadm connect r0
- at this point, we predicted that 2 primary split-brain is occurred and
drbd9 detect it.
But split-brain is not occurred, not detected. no debug log.
Just retry connection log is showing between two nodes.
Question is :
1) How can I test 2 primary split-brain situation ?
2) Does support 2 primary split-brain in drbd9 ?
drbd9's manual describe 'after-sb-2pri' option.
