I'm trying to get iSCSI working with my home lab setup.
I'm running FreeNAS 8.3.0-Release with iSCSI running on top of ZFS. My datastore consists of two 1TB SATA drives in a striped zdev. I have created 6 vdevs on this and am sharing one for each vm that I plan to host on the ESXi host. I've had this setup once successfully, but in testing it was torn down and rebuilt several times. I now cannot get the iSCSI link to work reliably.
The network consists of one cisco 3750G switch. It's configured for L2 only and the vlan setup for iSCSI is only configured on two ports (one for ESXi and the other for FreeNAS). The two servers are both running intel e1000 nics that are dedicated for iSCSI traffic, and FreeNAS, ESXi and the switch are configured for jumbo frames.
Currently, my switch interface is dropping out serveral times a minute on the ESXi interface. Because of this, it's throwing "istgt_iscsi.c:5239:worker: ***ERROR*** iscsi_read_pdu() failed" errors on the FreeNAS box. It has done the same thing before moving iSCSI traffic to it's own NICs, as well as before setting up jumbo frames and upgrading the ESXi box to 5.1.
If I've left any important info out, please let me know. If anyone has ideas of what to check, I'd love to hear them.
Thanks
