How long did you wait?
Once a zfs import took 1-2 hours to complete (it was seemingly stuck at

This seems like a reasonable proposal to enhance zfs list. But it would
also be good to add as few new options to zfs list as possible. So it
probably makes sense to add at most one of these new options. Or
perhaps add an optional depth argument to the -r option instead?

I don't know if VSS has this capability, but essentially if it can temporarily
quiesce a device like a data base does for warm standby then a snapshot
should work. This would be a very simple Windows side script/batch:

A question: why do you want to use HW raid together with ZFS? I thought ZFS
performing better if it was in total control? Would the results have been
better if no HW raid controller, and only ZFS?

swap them, and restore
