Re: Disk failure and event id 1146

If Monitoring software is opening handles directly to disk devices,
(bypassing normal IO stack or NTFS structures) then there is a possibility
that this could cause problems when cluster wants to lock the volume
(AFAIK: locking a volume is opening an exclusive handle, which returns an
error if a handle already exists)

Just for troubleshooting purposes I would disable any monitoring software
temporarily, which is relative simple to do, and not impacting any
operations of your cluster or application.
Two options:
1) the problem remains, which means that the disabled software is not
contributing to your problem, you need to investigate further
2) the problem goes away, which means that the disabled software is
contributing to your problem, now you can involve the appropriate software
vendor to investigate.

So, yes, it could possibly.

does that answer your question ?

In regards of your statement:

"Monitoring software both from your server manufacturer or
third-party could (not saying it is....) cause such behaviour.", do you
think that activating SNMP and Cacti software (http://cacti.net/) for the
scope of having statistics and so on, can produce such a behaviour?

What is your suggestion on this?
Thank you again.
