[Ocfs2-users] o2hb_do_disk_heartbeat:982:ERROR

Thu Sep 18 06:16:40 PDT 2008

Hi everyone;

The problem below changes into a "o2net_connect_expired" error. After examinig logs and other internet search staff we try o2cb configure again with the command

/etc/init.d/o2cb configure

Our scenario is that

After the installation of RAC the below (also above) problem occurs and after reconfiguring o2cb our problem node can mount san disks. What i want to ask is after a RAC installation is this something that we should do or what could be the relation between this problem and installation of RAC?

Only one node has this problem by the way, others could mount disks and if others mount disks problem node con not but if problem node mount disks the others can not?

What do you think?

Hi everyone;

I have a problem on my 10 nodes cluster with ocfs2 1.2.9 and the OS is RHEL 4.7 AS.

9 nodes can start o2cb service and mount san disks on startup however one node can not do that. My cluster configuration is :

node:

        ip_port = 7777

        ip_address = 192.168.5.1

        number = 0

        name = fa01

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.5.2

        number = 1

        name = fa02

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.5.3

        number = 2

        name = fa03

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.5.4

        number = 3

        name = fa04

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.5.5

        number = 4

        name = fa05

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.5.6

        number = 5

        name = fa06

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.5.7

        number = 6

        name = fa07

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.5.8

        number = 7

        name = fa08

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.5.10

        number = 8

        name = fa10

        cluster = ocfs2

node:

        ip_port = 7777

        ip_address = 192.168.5.9

        number = 9

        name = fa09

        cluster = ocfs2

cluster:

        node_count = 10

        name = ocfs2

when i manually try to mount disks i get an error says:

"mount.ocfs2: Transport endpoint is not connected while mounting /dev/emcpowerc1 on /oradisk/conf. Check 'dmesg' for more information on this error."

And when i check dmesg i see

(21125,1):o2hb_do_disk_heartbeat:982 ERROR: Device "emcpowerc1": another node is heartbeating in our slot!

I search similar problems but i can't find anything could u help me?

Thanx
