By default, FreeBSD does not allow zpools to be backed by zvols (that can be changed with the "vfs.zfs.vol.recursive" sysctl). When that sysctl is set to 0, the kernel does not attempt to read zvols when looking for vdevs. But the zpool command still does. This change brings the zpool command into line with the kernel's behavior. It speeds "zpool import" when an already imported pool has many zvols, or a zvol with many snapshots. https://svnweb.freebsd.org/base?view=revision&revision=357235 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241083 https://reviews.freebsd.org/D22077 Obtained from: FreeBSD Reported by: Martin Birgmeier <d8zNeCFG@aon.at> Sponsored by: Axcient Reviewed-by: Ryan Moeller <ryan@iXsystems.com> Reviewed-by: Alexander Motin <mav@FreeBSD.org> Signed-off-by: Alan Somers <asomers@gmail.com> Closes #11502 |
