[Linux-cluster] Linux-cluster Digest, Vol 92, Issue 14

Hi Nicolos,

Can you post your cluster.conf file. Do you have the unfence option enabled
in your cluster configuration. At times, system hangs out without allowing
the access to files during this scenario.

Thanks

I'm not sure I understand the problem here... can you post the complete
command sequence and show the permissions at each stage and what you think
should be different?

Hello all,

We've got a problem using a mirrored and clustered LV within a 5 nodes
cluster.

Everything is fine, except when a node leave the cluster, with cman_tool
leave, /etc/init/d/cman stop, electric poweroff or whatever.
In this case the storage just freeze on the others nodes, during 20 seconds,
until openais take into account the configuration change.

We can see this during the freeze in /var/log/messages :

?openais[3136]: [TOTEM] The token was lost in the OPERATIONAL state.
?[...]
?kernel: device-mapper: dm-log-clustered: [1lXq0Alc] Request timed
out: [DM_CLOG_MARK_REGION/405288] - retrying ?[...]
?openais[3136]: [TOTEM] entering OPERATIONAL state.

I'm running lastest 5.7, with :
?- kernel-xen-2.6.18-274.12.1,
?- cman-2.0.115-85,
?- lvm2-cluster-2.02.84-6
?- cmirror-1.1.39-10
?- kmod-cmirror-xen-0.1.22-3

Is this a normal behavior ?

Thanks for help
Nicolas AGIUS
