To allow = users to experiment with ZFS I use file-backed ZFS pools. On FreeBSD = 10.1 they cause a kernel panic.=20 For example a simple command like the following causes a panic: zpool = create /tmp/zfstut/disk1 This issue was identified in PR 195061: = https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D195061=20 And fixed in r274619 (2014-11-17): = https://svnweb.freebsd.org/base?view=3Drevision&revision=3D274619=20 However, even on 10.1-RELEASE-p9 the kernel panic still occurs (but = doesn=E2=80=99t on 11-CURRENT). Are there any plans to patch this in 10.1? I note it=E2=80=99s not in = the errata. My tutorials are not the only ones that use file-backed ZFS: new users = experimenting with ZFS on FreeBSD are likely to encounter this issue. Thanks, Will=
