Ocfs2 users - Mar 2006 - Getting eI am using RHLError when mounting shared OCFS2 device.

Hi,

I am using RHLE4 2.6.9-34.Elsmp with OCFS2 1.2.
The h/w for this 2 node cluster is connected correctly.
After loading ocfs2 on both nodes, the shared device could only be mounted
on one node. When I try to mount same shared device on second node then I
get following error.
Mount.ocfs2: Transport endpoint is not connected while mounting /dev/md0 on
/crs1

Any idea, why this is happening ?
Any help will be highly appreciated.
Thanks,

Sachin Vaidya

Connection failiure. Check dmesg.

Mount triggers the heartbeat thread which triggers the o2net
to make a connection to all heartbeating nodes. If this connection fails,
the mount fails. (The larger node number initiates the connection
to the lower node number.)

Obvious error would be incorrect ipaddr specified in cluster.conf.
Error messages in /var/log/messsages on both nodes will
provide more clues.

Hi,
Tried both public and private ip addreses but still not able to mount device
on both nodes.
Here are my configuration details.
hosts file : same on both nodes.

 127.0.0.1       localhost.localdomain   localhost
172.18.11.12    acspittdw001    acspittdw001.servicemetrics.net
172.18.22.1     priv-acspittdw001
172.18.11.24    vip-acspittdw001
172.18.11.13    acspittdw002    acspittdw002.servicemetrics.net
172.18.22.2     priv-acspittdw002
172.18.11.25    vip-acspittdw002

The cluster.conf on both nodes looks same as
node:
        ip_port = 7777
        ip_address = 172.18.11.12
        number = 0
        name = acspittdw001
        cluster = ocfs2

node:
        ip_port = 7777
        ip_address = 172.18.11.13
        number = 1
        name = acspittdw002
        cluster = ocfs2

cluster:
        node_count = 2
        name = ocfs2

Both nodes can ping each other on public and private ips.
The mount command produces following error on node 2 when device is already
mounted on node 1.

[root at acspittdw002 ~]#  mount -t ocfs2 /dev/md0 /crs1
mount.ocfs2: Transport endpoint is not connected while mounting /dev/md0 on
/crs1
[root at acspittdw002 ~]#

dmesg show following messages

SELinux: initialized (dev debugfs, type debugfs), uses genfs_contexts
(5027,2):ocfs2_initialize_super:1354 max_slots for this device: 8

ocfs2: Unmounting device (9,0) on (node 1)
[root at acspittdw002 ~]#

Any idea why this is happening ?
I can provide more details if needed.
Any help will be greatly appreciated.
Thanks in advance.

	md0?  What type of raid?  multipath, raid0, raid1, etc?  Are you
using persistent-superblock?
