Bug ID: 233745
Summary: [regression] [iscsi] ctladm devlist -v doesn't show
file backends for certain targets
Product: Base System
Version: 12.0-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: e...@norma.perm.ru
after upgrading some of my iSCSI systems to 12.x, I noticed that ctladm devlist
-v (and devlist -x) doesn't show file backends for a numerous targets. This
doesn't reflect their current state, because the initiators, using these
targets are able to fully access their block devices via iSCSI.
When modified, these targets may start to show their file backends, so the
exact nature of this behavior is currently unknown to me.
This behavior is new for 12.x and reproducible at least on the following
revisions:
FreeBSD san1.gcore1.playkey.net 12.0-PRERELEASE FreeBSD 12.0-PRERELEASE r340935
GENERIC amd64
FreeBSD san1.bsh.playkey.net 12.0-PRERELEASE FreeBSD 12.0-PRERELEASE r340754
GENERIC amd64
FreeBSD san1.gcore2.playkey.net 12.0-PRERELEASE FreeBSD 12.0-PRERELEASE r340933
GENERIC amd64
