Hello,

I think this is a md/softraid issue, because without md 
everything seems to be ok.

The setup:

I have two SCSI disks in an external box, connected via SCSI 
with two server machines and heartbeat running on both of them.
The filesystem is xfs with (soft-)raid1 exported via nfs.
The heartbeat script starts and stops nfs, the raid and does
the (un)loading of the corresponding kernel modules. Two clients
mount the exported filesystem and try to stress it. The system
disks of the servers are IDE.

The power of the primary server (as defined in heartbeat) is 
controlled from a timeswitch (2h on, 2h off).

What happens looks like this:

- the primary server gets switched off
- when the secondary server takes the disks the raid seems to
  be ok and it is never sync'ed
- after the primary server is back up again two hours later 
  the raid is always sync'ed

I would have expected it the other way round. Did I understand
something wrong or is there another problem?

After a few days of this 'test cycle' the filesystem is corrupt. 
Maybe because of that syncing, maybe due to other problems. But 
as i stated before without md everything seems to be ok.

The machines are PIII/800, the system is redhat 7.1 with kernel
2.4.6pre5-xfs (cvs checkout from oss.sgi.com)

Klaus.
