***ERROR*** lu_find_target() failed
|Reported by:||selled||Owned by:|
Hello, I am running FreeNAS build 8.0.4-RELEASE-x64(10351)on a SuperMicro? 6025W-NTR+B server.
I have 8-1TB drives in a RAID6 configuration, provisioned into two software extents, shared using iSCSI, one of which I am using as a shared VMFS datastore for a vSphere 5 cluster.
Routinely I encounter the following error message:
<<timestamp>><<freeNAS server name>> istgt: istst_iscsi.c:2008:istgt_iscsi_op_login *ERROR* lu_find_target() failed
The problem seems to be exasperated when there's a high volume of I/O happening at one time.
The major issue this causes is it causes any VMs running from that datastore to become inert, freezing their host, and rendering vSphere HA useless. I'm looking into products like Storage vMotion and Storage I/O Control to help mitigate this, but the problem with FreeNAS is too consistent to ignore.
