Hi,
I'm running a setup of open-iscsi connected to a target. When I run

I see various references to host reset, and finally one looks like

I'm using noop already, but that didn't help. I'll try to ask in lkml.
Thanks,

Using the sg3-utils package sg_dd command you can issue individual

Does anyone know why noop is not the default I/O scheduler?
It is a very bad idea in case of using a filesystem which is usually

The noop scheduler doesn't re-order requests, so concurrent accesses to
multiple files will cause lots of extra seeking and throughput collapses.
Hi,
Open-scsi solution is compatible with almost every solution.I have
worked with solutions like Solaris,Windows,LinuxIts working fine.
I have worked with vendor like Stonefly,Nexenta and DNF Storage and
found compatible with iSNS server.Its very easy to configure with
Stonefly and DNF

In my experience, noop works well on the initiator. On the target,
deadline is slightly better than noop on the target for the workloads

Thanks a lot for sharing your experience and
