[Ocfs2-users] 2 Node cluster, and nodes OS hang
Hello All,
I have a NAS that I would like to use ocfs2 on. Currently there are three
partitions made on it, I have included a fdisk listing below. I have created a 2
node cluster. I perform a basic mount, "mount -t ocfs2
/dev/ndas-00500435:0p3 /media/nas3". When I do this on the 2nd node..
after the 5 sec it takes to mount, the 2nd node will completely hang after 5
secs. I did see some local iptables blocks from the 2nd node. so I disabled the
firewall on both nodes, and that did not help.
I am using opensuse 10.1, kernel 2.6.16.21-0.25-default. I am fine with
troubleshooting the cluster not working, but completely hanging my system ?
