zfs discuss - Sep 2007 - Would a device list output be a reasonable feature for zpool(1)?

With the arrival of ZFS, the "format" command is well on its way to
deprecation station.  But how else do you list the devices that zpool can create
pools out of?

Would it be reasonable to enhance zpool to list the vdevs that are available to
it?  Perhaps as part of the help output to "zpool create"?

Seconded!

Yup...

With Leadville/MPXIO targets in the 32-digit range, identifying the "new
storage/LUNs" is not a trivial operatrion.

Just to answer one of my questions, "df" seems to work pretty well. 
That said I still think the zpool creation tool would do well to list what it
can create zpools out of.

Have a look at my devid/guid presentation for some details on
how we use them with ZFS/SVM:

Thanks for picking that up. .... the hand is quicker
than the eye, etc etc.

Sounds a lot like 4868036 "zpool create should have better support for
total
world domination".
