FreeNAS 8.04 iSCSI target incompatible with ESX clustering

[bjohns007]

Please reference VMware KB: http://kb.vmware.com/selfservice/mi...nguage=en_US&cmd=displayKC&externalId=1026596

When using OpenFiler to present iSCSI Storage to an ESX environment, you may experience these symptoms:
Frequent SCSI Reservation Conflicts reported in the VMkernel logs
Hosts become unresponsive to vCenter Server, vSphere Client, and SSH sessions
Data corruption on the VMFS Volume

KB article references OpenFiler, but FreeNAS experiences the same problems.

Is it possible to resolve this?

I think the devs are open to fixing things, but you have to keep in mind that there are only maybe 5 devs scattered around the globe working on this. If you consider all the features they are trying to incorporate for everyone, as well as fixing bugs, and trying to come out with new releases, it's quite a lot for them to keep on top of and keep everybody happy. Though they look at this "Bug" list, you're much more likely to get a resolution if you open a trouble ticket at support.freenas.org It just makes it much easier to track issues and have a "check list" for them to reference. Also having a LOT of patience helps too! ;)

Given the problems listed in the VMWare KB article, it sounds like it's a problem with IET rather than FreeNAS or OpenFiler. Your best bet would be to bring this to IET's attention.

It should be noted that FreeNAS uses istgt, not IET. Do either of the docs mentioned at http://doc.freenas.org/index.php/ISCSI#Connecting_to_iSCSI_Share contain settings on the initiator side that fixes these issues?
