This must be something else, as it only seems to affect zvols and iSCSI targets. Maybe I willl create a LUN using a file and hook that up to the same RAC cluster, if I don't get any of these errors with that, it has to be something in accessing the zvol. Maybe it's all COMSTAR's fault entirely…

I have a storage box entirely distributing zvols as LUN's through
Comstar for VM's. I have never experienced such problems so maybe it
has to do with the usage and some of the layers in between. Are there
any similarities between the used hypervisor and/or OS in VM's?
