Hello ,

Have four node cluster - was working fine - until our DHCP/DNS went down .
The cluster will now not show up on one host.  This host DID change IP
addresses as it was not static .
I updated all (4) /etc/ocfs2/cluster.conf . They are all identical.

cluster:
        node_count = 4
        name = saturn

node:
        number = 0
        cluster = saturn
        ip_port = 7777
        ip_address = 10.0.0.11
        name = nile

node:
        number = 1
        cluster = saturn
        ip_port = 7777
        ip_address = 10.0.0.32
        name = rio

node:
        number = 2
        cluster = saturn
        ip_port = 7777
        ip_address = 10.0.0.30
        name = mekong

node:
        number = 3
        cluster = saturn
        ip_port = 7777
        ip_address = 10.0.0.13
        name = volga

When either using fstab or direct mount I get :

root at mekong:~# service ocfs2 reload
Starting Oracle Cluster File System (OCFS2) mount.ocfs2: Invalid argument
while mounting /dev/sda on /titan. Check 'dmesg' for more information on
this error.

mount -t ocfs2 /dev/sda /titan
mount.ocfs2: Invalid argument while mounting /dev/sda on /titan. Check
'dmesg' for more information on this error.

And in dmesg I get :

I have found found several "node mismatch" and "ERROR: status = -22"
issue(s) but none seem applicable .

Any suggestions welcome .

Thanks ,

J.R.
