There are mixed device names in the 'zpool status' and some contain "-part1" in the name.

A device with "-part1" in the name is seen when a pool is created before multipathing was enabled on the system.
If the device does not have the "-part1" in the name it is an indication that a new drive was added after multipathing was enabled.
This is not a problem as we support either way as well as mixed and QuantaStor will handle partition devices like these just fine.
If you see "-part1" in the DM devices names before you create a pool then it's best to format the devices before you create the storage pool.
This will clear out the partitions and give you a clean start for pool creation.
