Hi,
I've created two node cluster ( https://docs.oracle.com/cd/E52668_01/E54669/html/ol7-ocfs2.html ).
I have local heartbeat, ocfs2-tools.x86_64 1.8.0-17.el7, 3.8.13-98.7.1.el7uek.x86_64, dedicated lan for ocfs2 nodes.
All is done by this guide. I've tryed to test it, and with one node up and other in reboot, other come in cluster normally.
But when I reboot both nodes in same time, often only one node mount shared fs, but other not.
When I look at the status of o2cb on node where mount is missing I get:
# service o2cb load
Loading filesystem "configfs": OK
Mounting configfs filesystem at /sys/kernel/config: mount: configfs is already mounted or /sys/kernel/config busy
configfs is already mounted on /sys/kernel/config
Unable to mount configfs filesystem
Failed
And I have to umount /sys/kernel/config and then do the load, start o2cb and start ocfs2
Is there any way to overcome this? Maybe dedicated hartbeat disks ( global )?
Regards
