Physical disk hangs at "offline pending"

Hi,

I have a 2 node cluster that works correctly when the active server goes down.
All resources are taken over by the passive member.

When I try to move resources from node 1 to node 2 everything works fine as
well.
The problem is that when I try to move the the resources back to the
original node all resources move except for one physical disk. This physical
disk status remains as "offline pending". The cluster log contains many
entries similar to what follows:
"FmpofflineResource: offline resource <drivex>returned pending"
until finally
"RmpTimerThread: Resource drivex pending timed out, CP 3 - seting state to
failed."

The only way for us to get the offline resource available for the other
cluster member is to reboot the server that failed to put the physical drive
offline.

Any ideas would be appreciated.

Thanks in Advance,

Henry

Re: Physical disk hangs at "offline pending"

Sounds like something has a handle to the drive that is preventing cluster
from completing the Offline process. What kind of group is this disk
resource in?

Re: Physical disk hangs at "offline pending"

Hi,

We have installed Oracle failsafe on this cluster and the drive in question
is part of the "Cluster Group" set of resources. The oracle database resides
on this SAN drive. I have stopped all oracle services on the server giving me
the problems and the disk still does not go offline to enable a failover
unless the server is shut down.
I suppose there must be something else preventing the failover and am trying
to determine what could be preventing this disk from being released. The
server in question does have exclusive rights to this physical disk when it
is the active member.
If anyone has any idea as to how I might determine if some process is
refusing to release it's resources please make a suggestion.
Is there a way to increase the logging level of the cluster and should that
give me a better indication of what may be the problem? (the logs are fairly
hard to decipher even at the default logging level).

Thanks in Advance,

Re: Physical disk hangs at "offline pending"

Henry,

just a few questions:
- is this Oracle FileSystem (ocfs.sys) ?
- what errors do you see in the system event log (please post) ?
- what errors do you see in the cluster.log (please post) ?
- once the disk is in off-line pending state... what other cluster resources
are off-line pending ?

thnx,
edwin.

Re: Physical disk hangs at "offline pending"

Hi,

1) No. The file system is NTFS.
2) Event ID 1145 - Cluster resource OracleDB timed out. (Physical disk name)
Event ID 1205 - The cluster service failed to bring the resource group
"OracleDB" completely online or offline.
3)00000f7c.00000810::2007/03/01-15:51:35.805 INFO [FM] FmpRmOfflineResource:
RmOffline() for 5fa5cc41-66f4-4b14-9d9c-32c7f67347a5 returned error 997. ---
0000c20.00000f18::2007/03/01-17:56:22.860 INFO [FM] FmpRmOfflineResource:
RmOffline() for 667e7691-4049-44fe-9380-c620cd79971d returned error 997

The following entry is repeated:
00000c20.00000a60::2007/03/01-17:58:25.379 INFO [FM] FmpCompleteMoveGroup:
Exit, status = 997
00000c20.00000a60::2007/03/01-17:58:25.875 INFO [FM] FmpCompleteMoveGroup:

until finally:
00000c20.00000a60::2007/03/01-17:59:40.276 INFO [FM] FmpCompleteMoveGroup:
Exit, status = 997

Resource OracleDB pending timed out, CP 3 - setting state to failed.

This last messege may be the result of us getting fed up and shutting down
the server that will not release the physical drive.
4) The other resources are offline. On the odd occasion another physical
disk displays the pending offline symtoms as well.

Thanks in Advance

Re: Physical disk hangs at "offline pending"

Answer me this, when you look at the properties for this disk resource and
inspect the 'dependencies' tab...is there anything listed there?

Re: Physical disk hangs at "offline pending"

Hi,

No, there are no dependencies for this resource.
That is what I expected for a physical disk resource.

Thanks in Advance.

Re: Physical disk hangs at "offline pending"

Hi,
In order to determine who is holding the HD resource, do the following.
1. Restart and bring everything up and running on node 1.
2. Take offline everything except the cluster.
3. Do failover to Node 2
4. Bring online only the HD in questin
5. Do failover back to Node1

If step 5 is not succeseful, then there is process external to the cluster
that i causing the problem. Antivirus scan or something like that.
If step 5 is succeseful, then the problem is in your Oracle setup. In this
case you have to send more details about your configuration.

Hope that helps

Krass

Re: Physical disk hangs at "offline pending"

Hi,

Pardon my ignorance but I'm not sure what is meant by "take offline
everything but the cluster". If that means the cluster group, it was modified
and contains:
Cluster IP
Cluster Name
Quorum disk physical disk
Oracle log physical disk
Oracle DB physical disk
Images physical disk
Oracle Services for MSCS
Several file shares dependant on the physical disks.

The other groups (2 for different instances) contain:
Oracle Database
Oracle failover IP address
Oracle Listener
Oracle network name

This is not how I originally configured it but it was changed by the DBA
that installed Oracle failsafe.

The two servers are identical (HW and OS).

Thanks in Advance,

Re: Physical disk hangs at "offline pending"

Henry,
By "cluster" I ment
Cluster IP
Cluster Name
Quorum physical disk
That's it. Take all other resources offline.

BTW, as best MSCS practice you should not use the cluster goroup for
anything else but the above, + MSDTC maybe. In fact, your problem may be
related to that.

Hope you manage to figure out what's holding that drive.

Re: Physical disk hangs at "offline pending"

Hi,

OK I had everything offline except the cluster IP, Name and Quorum.
Failed over to second node with no issues (This is always the case)
Then I brought the physical disk(s) in question (2 actually) on line.
Tried a failover back to the first member of the cluster and the same thing
happened. The physical disk(s) in question stayed in the "offline pending"
state.

Thanks in Advance,

Re: Physical disk hangs at "offline pending"

Henry,

I think here we go wrong.

The disks your Oracle instances are using are not in the same group of your
Oracle instances.

so, this is what I think here is happening.
Cluster group online on node 1
Oracle group online on node 1

Oracle is happy, as its disks are accessible.... as they are all on node 1.

Cluster group wants to move over, tries to offline the disks, however your
Oracle instances still have a handle open on the disks, and therefore the
disk remains off-line pending until time out.

I seriously believe you need to change your configuration.

The cluster group should only contain the following :
1) Quorum disk
2) Cluster IP address
3) Cluster Network Name

Each of your Oracle groups need the following
1) IP address
2) Network Name
3) as many disks as this Oracle instance need, these disks can only be used
by this instance exclusively
4) Oracle services / applications for this instance.

Other than this, follow Oracle instructions for building your cluster,
invoke Oracle support for getting more information on how to configure your
clustered applications.

Rgds,
Edwin.

Re: Physical disk hangs at "offline pending"

Hi,

You are probably right about the group configuration and I will do some
research into it today.

Since the group move works fine from node 1 to node 2 but doesn't work going
from node 2 to node 1 I'm not sure that group configuration is causing my
problems.

Even with all the oracle services offline and only the Cluster IP, name,
quorum and the 1 physical disk online a move from node 2 to node 1 leaves the
physical disk as "offline pending" while a move from node 1 to node 2 works
fine.

I am going to seeif I can find any differences that are not obvious between
the nodes first. Then I will try re-arranging the groups.

Any other suggestions would be appreciated.

Thanks in Advance,

Get Oracle support involved and let them tell you how to configure your
groups/resources/disks.

Re: Physical disk hangs at "offline pending"

What happens if you have only one disk online, or only attempt to take a
single disk offline? Does this work?

If it works with a single disk at a time, as a work-around you could make
one of your disk resources depend upon the other so that only a single disk
goes offline at a time.

If the above works for you, I have seen this once at a customer's site but
never really found a root cause. My customer wound up re-installing their
O/S and this resolved the issue.

Regards,
John
