Subject:   zpool component names - gpt vs. gptid
Message-ID:  <5459E89F.7080801@qeng-ho.org>

next in thread | raw e-mail | index | archive | help
These days I use GPT labelled partitions (/dev/gpt/<label>) exclusively 
when creating zfs pools. However, on my latest box, where I have two 
pools each with a single component, "zpool status" lists the components 
as gptid/<uuid> rather than gpt/<label>

Is there any way to persuade zfs/zpool to use the GPT label devices 
rather than the gptid devices? Failing that, how do you map gptid's back 
to the underlying disk partitions? It's obvious in this case, but I'm 
building a new file server with eight identical disks in a raidz2 set up 
and am worried how I'll identify which disk has problems in the future.
