Hello,
I have a Mac Mini from 2011 w/ Mountain Lion (OS X 10.8.2) and 16GB RAM running ZEVO Community Edition 1.1.1. Connected to it is a WD 8TB Thunderbolt.
Whenever I connect with a single machine to a share exported from my "ZFS NAS", things seem to work well. However, once I connect with more than one machine (e.g. one connection from a Windows 7 machine, and one from a Macbook Air) to the same share and start browsing or copying files, the share suddenly can't be accessed from either of these computers. I can still browse and view/copy files if I use the Mac Mini itself, but not from any other remote computer using SMB. I'm using the same credentials to connect to the ZFS share from both computers.
Usually the fan on the Mac Mini will also kick into high gear at the same time I lose connectivity from both remote machines, and it will run for 15 minutes or so before quieting down. Running "top" shows no high CPU usage for any particular process, though (i.e. none more than 1-2%, except top itself which might use some more).
I've had this problem also with previous versions of ZEVO. I'm not sure if it's due to the ZEVO implementation, the SMB protocol, the sandboxing policy on OS X, or something else. Sometimes I've seen ZFS errors when running dmesg (see below), but these don't seem to show up consistently.
Example output from dmesg:
Sandbox: sandboxd(60874) deny mach-lookup com.apple.coresymbolicationd
Sandbox: sandboxd(61011) deny mach-lookup com.apple.coresymbolicationd
Sandbox: sandboxd(61153) deny mach-lookup com.apple.coresymbolicationd
zfs_secpolicy_write_perms: duo/nas error 89
Sandbox: sandboxd(61233) deny mach-lookup com.apple.coresymbolicationd
Sandbox: sandboxd(61371) deny mach-lookup com.apple.coresymbolicationd
Sandbox: sandboxd(61510) deny mach-lookup com.apple.coresymbolicationd
Anybody has experienced the same issue with ZFS and SMB or know what could be going on here? I'm considering trying NFS instead, but would really prefer to use SMB.
