Re: [Linux-cluster] What does this mean? "Resource groups locked, not evaluating"

2009-03-18 Thread Corey Kovacs
Dan, a quick google reveals the patch from whence this log originates and appears to have replaced a message that read "Services locked". If you are seeing these only after bootup, I suspect that it's just a condition of the cluster booting up and rgmanager not allowing things to flip from node to

2009-03-18 Thread Hunt, Gary
I was fighting a very similar issue today. I am not familiar with the fencing you are using, but I would guess your fence device is not working properly. If a node fails and the fencing doesn't succeed it will halt all gfs activity. If a clustat shows both nodes and the quorum disk online, bu

[Linux-cluster] Service is not migrated when owner fails

2009-03-18 Thread Maykel Moya
I have a 4-node cluster, each node running one of four services. Each service is an ip/fs combination. I'm trying to test service failover. After disconnecting the network to one of the nodes (ip link set eth0 down), its running service is not migrated to another node until the node get successfull

All, I currently use the fence_mcdata script (with slight mod) to provide fencing to my DS-4700M switch. I have two questions: 1. The username and password are stored plain text within the cluster.conf file. Is there a way to make this more secure? (password script?) 2. fence_mcdata works by

Oh, just ignore this stupid question. I didn't read the man page carefully. This sentence from the man page solves the problem: "gfs_jadd will not use space that has been formatted for filesystem data even if that space has never been populated with files." I extended the lvm and then grew t

Hello all I have a two-node cluster with a quorum disk. When I pull off the power cord from one node, the other node freezes the shared gfs-volumes and all activity stops, even though the cluster maintains quorum. When the other node boots up, I can see that "starting fencing" takes many minutes
