[stgt] iSER issues in RHEL 5.3

[Chris Worley]

Configuration: RHEL 5.3, 2.6.18-128 kernel, OFED 1.4.1

With one lun exported, running "fio" with 1MB blocks, I get sporadic
errors on the initiator like:

sd 4:0:0:1: timing out command, waited 360s
sd 4:0:0:1: SCSI error: return code = 0x06000000
end_request: I/O error, dev sdb, sector 3921920
sd 4:0:0:1: timing out command, waited 360s
sd 4:0:0:1: SCSI error: return code = 0x06000000
end_request: I/O error, dev sdb, sector 3962880

No problems reported on the target.

With multiple LUNS exported, the tgtd hangs on the target as soon as I
try to benchmark the LUNs (login was sucessful).

iSCSI seems fine (but slow), iSER seems problematic.

Any ideas?

What are good known configurations (distros/kernel/OFED) for iSER?

Thanks,

Chris
