[OpenIndiana-discuss] Access to ZFS viz CIFS fromwindows regularlyhangs.

[Mike La Spina]

> Does the suspend event only occur on SMB clients or does it impact the
other storage clients when triggered by the Windows clients?

It does not seem to effect the vmware hosted machines via nfs. Next time
it hangs I will try a nfs transfer to it.
- If this is correct its a further indication of an AD/SMB issue, but
not verified at this point.

> Any domain controller event errors?

Yes there are, I will go and resolve this first before I go any further.

- Highly suspect this is where you need to focus.
- This error is suspicious and does look like a issue on the domain.

smbrdr_exchange[4]: failed (INVALID_HANDLE)
- I would look further back in time and see if it correlates with the
suspended access event. That would define a clear resolution path.

> dmsg output?

Attached - is this the correct etiquette?

- The time slider snapshot service failed? Or was it stopped manually?

> fmdump -eV output?

Also attached.
- Nothing remarkable

> uname -a output?

SunOS ringwood 5.11 oi_148 i86pc i386 i86pc Solaris

> Have you attempted a packet capture of the event?
> snoop -o smb-client.cap <clientip>

Not yet, It could be caputureing for 4 hours before it happens, I will
resolve the AD domain issue first.
- Good approach. 4 hours of packet tracing is hard to digest! It would
certainly need to be truncated down to the trigger event.
