Hello,
We were experiencing issues with large file deletes and spikes in latency from our Netapp filers. We run v3240's and FAS2240's. All are running 8.1.2GA or 8.1.1GA. The problem was only observed on those filers running 8.1.2GA.
One operation that was observed to causing the problem consistently was Storage vMotions from an NFS datastore. In particular, the tail end of the Storage vMotion when the guest machine's files were deleted from the datastore seemed to trigger the problem.
It looks like other people were experiencing the same issue. NetApp confirmed that a bug existed related to the deleting of large files. That issue was addressed in 8.1.2P3. We decided to deploy 8.1.2P4 as it included additional fixes related to deleting large files.
Has anybody else deployed 8.1.2P4 yet? We just completed our deploy of 8.1.2P4 and it seems to have resolved the issue with large file deletes. We've tested a few Storage vMotions and removals of VM's with no issues thus far.
If you are using 8.1.2P4, have you observed other issues?
Thanks, Phil
