problem with minifilter driver , failover environment, IRP_MJ_SET_INFORMATION, share access with smb3 feature high availability
Hallo, i use a minifilter driver to collect file activities (like the minispy example). Now i have a problem in a special environment use case. Testenvironment: 3 node failover cluster (MS 2012 R2), role "file server", set share access with high availability feature (Default) (smb3 transparent failover); The test is a simple rename of a file. In case of check IRP_MJ_SET_INFORMATION in pre and post callback the client side initiator application explorer freeze or if i use powershell or command console the action is not allowed. If i disable the driver the test run. Shares without this HA-Feature and running minifilter driver also runs. Any idea what is wrong. Thanks

Does this happen with a stock version of minispy? Have you looked at Process Monitor and/or WireShark traces from the working and non-working cases? -scott OSR @OSRDrivers "Jörg Wittig" wrote in message news:102060@ntfsd...

Only with the smb3 feature high availability did i have trouble. All other situations works fine. If i have interaction with filter manager wait for callback and leave the callback the initial function is not executed. I had forgot to say the filter runs on server side. Best regards Jörg

I'm not sure you answered my question...Does this some failure happen if you use the minispy sample and HA? Or just with your filter and HA? -scott OSR @OSRDrivers "Jörg Wittig" wrote in message news:102103@ntfsd...

Hi Scoot , the problem occurs with my filter and HA. The minispy sample implementation served as a base model (concept). my filter on -> share with HA -> problem if rename triggered, other file actions are not affected my filter off -> share with HA -> no problem my filter on -> same share HA off -> no problem greetings and thanks for the support jörg Am 17.01.2017 um 20:59 schrieb Scott Noone: > I'm not sure you answered my question...Does this some failure happen if > you use the minispy sample and HA?

What I've been asking is if you take the minispy sample *as is* and install it on the server, do you get the same behavior? If not, then there is something in your processing that is different and causing the issue. At least you would have a working and non-working case to compare. Other than that, there is not enough detail here to provide any additional insight. -scott OSR @OSRDrivers "Jörg Wittig" wrote in message news:102124@ntfsd...

Hi, ok, the test with the original is a possibility. i hope to find the time (certainly on weekend) for the test. My first thought was: Why run all other situations (copy, ACL change, create,... ) without trouble and only rename failed. I'll get back after the test. thanks Am 18.01.2017 um 18:28 schrieb Scott Noone: > What I've been asking is if you take the minispy sample *as is* and > install it on the server, do you get the same behavior?

<QUOTE> My first thought was: Why run all other situations (copy, ACL change, create,... ) without trouble and only rename failed. </QUOTE> No way to tell without data...You need traces and some experiments. As I mentioned previously, WireShark data from the working and non-working cases might be useful as well as ProcMon traces (on the server and/or client). -scott OSR @OSRDrivers "Jörg Wittig" wrote in message news:102132@ntfsd...
