File Share disappears after upgrading to OS X Mavericks

Thread needs solution

I recently started with a new company that uses ExtemeZ-IP on Windows Server 2012. An issue that has been ongoing and quite frustrating is that one of the shared folders that is heavily used will intermittently disappear, only to reappear a few minutes later. When it occurs, all aliases to the folder have to be remapped and anyone accessing the folder is kicked from it. I can't seem to find any rhyme or reason for it and have tried multiple things such as updating ExtremeZ-IP (currently on 9.0.2) and increasing the buffer for all volumes in the registry on the server to 512 from 256. The issue seems to have started when everyone upgraded to Mavericks and it was working fine when on Snow Leopard. The only current workaround we have is to connect via SMB instead of AFP but there are a lot of functions of ExtremeZ-IP that are missed dearly. Has anyone else had this issue?

We've discovered the same situation after upgrading to Mavericks from Snow Leopard. When using Adobe CC 2014 apps, the macs will simply "hang" for approximately 2 to 5 minutes before coming back to life. This will happen 2 or 3 times through out the day. Upgrading to ExtremeZip 9.02 hasn't helped.

I did end up finding a resolution for this. Just to be clear, we have a shared volume that has 6 folders on it accessed by multiple groups of users. One of those 6 folders is what would disappear, and it would happen every 10-15 minutes throughout the day. The volume itself never disconnected, just one share that was on there.

I'm not sure why it was setup this way, but the volume and the folder that was disappearing have the same name. Even though it seemed to work fine with Snow Leopard, I started assuming this may be an issue.

The end result was to create a separate shared volume for that folder that was disappearing. Once I did that (named the same thing but with a 2 at the end), it stopped disappearing. I'm not sure if it's b/c it's a high traffic folder and just works better as it's own dedicated shared volume, or if Mavericks had an issue with the name similarities. But, either way it's functioning correctly now and the users are very happy to be connecting via AFP again.

Mike, we thought initially that you were talking about disappearing volumes. However, we figured out that it is about one particular folder only (the confusion was caused due to the fact that the affected folder has the same name as the volume where it is located). So, you created a new volume using that affected folder and the issue has gone. Hence, the support case was closed but I would like to share some general troubleshooting steps for other forum members:

re: Volume disconnection
1. Install and run EZTcpdump on the Mac client:
- Mount EZIP Volume and configure EZTcpdump as follows:
o Store Path: select your desktop
o Configure Automatic Stopping: Check the tick box + select root of the EZIP Volume when asked to enter path (this should be the volume you are getting disconnected from).
- Hit the collect button to start the capture.
- The next time you get disconnected from the Volume being watched under "Automatic Stopping" the capture will stop.
You can leave the packet capture running all day until the problem occurs. The packets will be written to 5x50MB files, newer packets will overwrite older packets so your drive won’t fill up.
- Note the time the volume went away, the time of remount and the user or IP address.

2. Contact Mobility Support and provide the collected dumps.

3. Sometimes it can be just a Sidebar issue (shared items triangle) where the server appears to be disconnected but you are really still connected. How to check it? 1. If you do a Go -> Go to folder -> /Volumes, do you see you are still connected? 2. Or do you see yourself connected if you have Finder preference set up to display the volume icon on the desktop?

re: Folders disappearing
1. Let’s see if the following registry change solves the issue:
a. Open the registry: Start Run -> regedit
b. Navigate: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ExtremeZ-IP\Parameters4\Refreshable
c. Change 'EnumerateExtraItems' from 0 to 1
d. Open the EZIP Admin -> Settings -> Click “refresh registry”

2. If the above fails to solve, then:
a. Open the registry: Start Run -> regedit
b. Navigate: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ExtremeZ-IP\Parameters4\DebugLogging
c. Change 'AfpCommands' from “GLOBAL_SETTING” to “D”
d. Change ‘AppleDouble’ from “GLOBAL_SETTING” to “S”
e. Change ‘Enumerations’ from “GLOBAL_SETTING” to “S”
f. When the issue occurs, note the time and client IP address and send us the corresponding debug log (Right-click the folder C:\Program Files (x86)\Group Logic\ExtremeZ-IP\Logs and select Send To -> Compressed Folder).

Thank you!
