iSCSI w. Server 2008 R2 locks up on large writes
I have a ReadyNAS Pro Business Edition [X-RAID2] running RAIDiator 4.2.19. The entire thing is running one iSCSI LUN connected to one physical host. When I try to copy a large amount of data to it (...
You mean the iSCSI LUN is 9TB? We reserve 10GB, so you can't occupy the entire volume with an iSCSI LUN, so it should only end up 99.9999%(you get the idea) full. The only way to actually fill it completely would be to have 10GB of data copied to a share on the ReadyNAS via CIFS, FTP, or something else.
Does that HP procurve have any management settings configured for the port like flow control? Is the flow control setting on the port matching the iSCSI client(if you have flow control disabled on that port, then it should also be disabled on the client, and the port that the client uses).
Shouldn't be a jumbo frame issue unless you have jumbo frames enabled on something else, since they were disabled on the ReadyNAS when you sent us the logs. Are jumbo frames still enabled on the switch or client?
Rebooting the system will reset that error count. If you do see the error count increasing while you're writing to the readynas, you don't have to continue until it fails.
