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 (...
Hello,
I'm seeing the same issue. When using Veeam and writing to my ReadyNAS 3200, the MS iSCSI initiator essentially locks up some times. The lock up is intermittent. It have tired different types of Server 2008 R2 virtual servers (different patch levels, etc.) and still have the same intermittent issues. When the issue occurs, in Resource Monitor, I can see the logical volume have 100% active time, 0 disk queue length and no changes.
When Veeam is working, it writes at a maximum of about 29 MBps.
I turned the NAS on yesterday and have 718554682 RX packets and 1202679 RX dropped packets. I have no dropped TX packets.
I do not have Jumbo Frames turned on on the switches or NAS. We have redundant HP switches, ESXi 4 servers and an iSCSI SAN. We have not had any issues with iSCSI for 2 years since the SAN's installation.
We are on RAIDiator 4.2.19.
Can you give me suggestions of some more options to try?
Thanks,
Todd
