The following reply was made to PR kern/162342; it has been noted by GNATS. From: Garrett Wollman <wollman@hergotha.csail.mit.edu> To: jeff@bovine.net Cc: freebsd-gnats-submit@freebsd.org Subject: Re: kern/162342: FreeBSD hides gpt labels after mounting ZFS partitions Date: Sun, 6 Nov 2011 23:17:04 -0500 (EST) jeff@bovine.net submitted the following bug report: >If you use "gpart" to create a GPT disk with partitions that have gpt >labels defined, then those labels are normally visible in /dev/gpt/ > >However, once any of those partitions are used by a ZFS pool that is >imported, the label disappears from /dev/gpt/ Not in my experience. They only disappear if ZFS is opening the underlying partition devices rather than the label devices -- i.e., in the usual case, you did a "zpool create foo /dev/ada0p2 /dev/ada1p2" rather than "zpool create foo /dev/gpt/data0 /dev/gpt/data1". I suppose that if you created the filesystem on another device and let "zfs import" find it by groveling around through all the GEOM providers on the system, this might happen. What does "strings /boot/zfs/zpool.cache | fgrep /dev" say? -GAWollman
