Problem ======= When we fail to open or import a storage pool, we typically don't get any additional diagnostic information, just "no pool found" or "can not import". While there may be no additional user-consumable information, we should at least make this situation easier to debug/diagnose for developers and support. For example, we could start by using `zfs_dbgmsg()` to log each thing that we try when importing, and which things failed. E.g. "tried uberblock of txg X from label Y of device Z". Also, we could log each of the stages that we go through in `spa_load_impl()`. Solution ======== Following the cleanup to `spa_load_impl()`, debug messages have been added to every point of failure in that function. Additionally, debug messages have been added to strategic places, such as `vdev_disk_open()`.
