what about open files on an mscs cluster share?

[kruegste]

Hi everyone,

we are using an w2k3-enterprise-based MSCS-Cluster as fileserver in our enviroment.
on this cluster resides our home-drives/shares with all the files per user.
as we use lotus notes via windows terminal servers with citrix we had to put the notes\data-directories on the mscs-cluster into the home-drives.

now here is the problem. If we have a planned or unplanned failover of the file-server-group in the cluster, the notes-programm crashes. i think that there are open files in read/write-mode on the clustered shares and after the failover this information is lost due to the notes crash.

Is that right? Are there any workarounds? can i manipulate these behaviour by configuration?

thanks for advice.

This is expected. When the cluster moves from one node to another all the services and shares are shut down, dropping your clients connections to the files. When the resource group starts on the other node the services and shares are restarted.

Thank you Denny,

i assumed that...

has anybody experience to avoid this by using the offline-cache in windows as to be a workaround?

thanks for advice.

This is a limitation of using CIFS on one side and Notes on the other. The protcol has now allowance for failover of live sessions. Gnoats isn't intelligent enough to attempt a reconnect after the session dies.
