Hello toasters: Can anyone explain what CIFS operations that are neither read nor write operations? In addition, can anyone think of what process(es) could be causing these?
ops/s reads(n, KB/s) writes(n, KB/s) suspect/s 860 | 0 0 | 0 0 | 0 |
We have 1500+ windows 7 workstations connecting to their homeshares on this head. Lately we have been seeing CIFS latency where the user workstations are hanging within their windows explorer window. When this occurs, a cifs top shows high "ops/s" with no associated reads or writes. We are running DATA ONTap v7.3.5.1P1.
Any insights would be greatly appreciated.

In short, attribute lookups and directory listings. In long, it's hard to tell the root cause without seeing the big picture within the auspices of a support case. For example, what you describe could simply be a symptom of a broader issue or even a mere client configuration change. It's hard to tell, but hopefully you have enough to get started.

These are typically process that scan folders. If you traverse a large number of directories and have a process that scans for folders. Look at antivirus scans or fpolicy tools that track file age, and usage.
We scan 100000+ documents nightly and if an antivirus scan or fpolicy scan hits at same time our 3050 starts crawling.
