Error 64, File Server Cluster [message #158146] Mon, 14 September 2009 16:51 Go to next message

We have a File Server Cluster (Win2k3EE R2 x64), 2 nodes Active/
Passive, directly connected to a SCSI drive array serving as the
backend for multiple web servers. There are a total of 8 IIS servers
on the front end (Active/Passive behind a load balancer, so only 4 are
active at any one time) that store some file persistence and content
on the file cluster. The websites application roots are located
locally on the web servers, and there are multiple virtual directories
pointing to the cluster.

Occasionally we are receiving some errors with regards to the shares
going offline with error 64 in the cluster.log file. In a few
instances we have received event id 1055 in our event log. I have
followed KB article # 961657, http://support.microsoft.com/kb/961657,
to try and fix this issue, but to no avail. MS PSS have also
recommended that KB article as a fix. I have even bumped up the max
work items to 16384 to try and fix it, but it still happens, although
not as frequently.

My first gut instinct on the matter is that the file cluster server
service is being overwhelmed with SMB requests as a result of File
Change Notifications from ASP.NET and simple file requests from IIS.
I made the registry changes on the web servers documented in KB
911272, http://support.microsoft.com/kb/911272, to try and reduce the
number of File Change Notification Objects being created, but because
the directories being accessed on the cluster are virtual directories
rather than the application root, the FCNMode change has had only a
little effect.

MS PSS has not come through with a fix for this, rather just
incremental changes that really have had zero effect. Does anyone
have any insight on these types of issues?

Thank you

Brian

We were having similar problems with a couple of clusters with Dell/EMC san
storage. Dell updated all the SAN component, server drivers and navisphere
and the porblem has not occurred since.

Well unfortunately we are using a DAS storage array rather than a SAN,
and it is using MS's built in SCSI drivers. I have already updated
the NIC drivers to the latest, but still no luck.

Hmmm, I spoke too soon, had another one over the week-end. Must have jinxed
it :)
If you find a solution be sure to post, as will I.

Cheets,

PS One thing I have noticed is that it seems to happen when some folders
with many thousands of sub-folders and a very deep tree structure is being
accessed. ??

Our cluster is failing with the same error again. I am thinking about
increasing the MaxWorkItems yet again since it is a 64-bit install, we
don't have to worry about kernel memory nearly as much as a 32-bit
system. Does anyone else have any ideas?

Thanks

Brian

Not sure if this is solved yet, but usually error 64 is caused by starvation
of memory (pool, non-pool)
I would open a case with Microsoft support to further investigate

HTH,

Would adding more physical memory help resolve as that would be easy and
cheaper than the time lost in failures while continuing to investigate?
