Cluster Node has lost active resources

[stu1892]

Hi.

 

This seems to have happened randomly last week and i only noticed because the backup has failed.

 

We have two nodes clustered node1 and node2. Node2 should have resources and now hasn't. Node1 has taken them.

 

I know this should fail back over, however, node2 has lost it's drives in "my computer". Normally if it fails over to node1, the drives are there to see. Now they're not and i'm completely lost.

 

Tried a couple of reboots and the order i booted them in. Node2 boot first and brought up no extra drives at all. Node1 booted and had all the drives and owned all resources. Cluster Admin can also see node2 as far as i can tell.

 

If i have missed out any information just ask and i'll try and explain. I'm a complete novice with Cluster etc and don't want to go randomly clicking.

 

Cheers in advance,

Stu.

Have you been into cluster Administrator and tried to fail them back manually??

 

Are there any event log errors???

Thanks for the reply.

 

How would i try failing it back, is there a simple button that i'm completely missing? Or does it involve taking node1 offline?

 

Nothing in eventlog that jumps out which was a nightmare as i it could have happened any time after last Wednesday night!

If i initiate failure on one of the resources, it just comes straight back online again on the same node.

 

There are no visible disks in 'my computer' other than the local C drive. Normally if it fails over, the drives are still visible but aren't accessible, obviously. Now there are no drives there.

Well, something came up in eventvwr after i tried to initiate failure.

 

"The disk associated with cluster disk resource 'Disk H:' could not be found. The expected signature of the disk was F615BF09. If the disk was removed from the server cluster, the resource should be deleted. If the disk was replaced, the resource must be deleted and created again in order to bring the disk online. If the disk has not been removed or replaced, it may be inaccessible at this time because it is reserved by another server cluster node."

 

Not sure what to make of it.

Just seen that node2's driver for fibre channel has a problem. This goes into the tape drives.

 

I'm going to uninstall the driver and hope a reboot will install it correctly and i'm back up and running. Fingers crossed!

If you need to manualy fail the cluster resource over

 

open cluster administrator

right click on the active resource

click take off line

 

should then go offline on that node and come back on other node.

Thanks for the help.

 

The problem was the fibre connection. The driver had became corrupt.

 

I added some different drivers and now the share i wanted to see has shown up.

 

If i hadn't have been cleaning behind the cabinet this morning, then i wouldn't have known that the servers were connected to the disk libraries by fibre! Stroke of luck!
