From 6cb7ab069d9079a5b4b955da883d5ab804c91319 Mon Sep 17 00:00:00 2001 From: Andrew Reid Date: Sat, 13 Oct 2012 12:03:59 -0300 Subject: [PATCH] Do not return /dev/loop-control in unused_loop_device The function unused_loop_device in /usr/libexec/zfs/common.sh returns /dev/loop-control on the first call. This device is NOT a loop device (https://github.com/torvalds/linux/commit/770fe30) it is a control device. This in turn causes the script zconfig.sh to fail with: zpool-create.sh: Error 1 creating /tmp/zpool-vdev0 -> /dev/loop-control loopback The patch makes the function return /dev/loop[0-9]* which are loop devices.
