Bug ID: 225546
Summary: "zpool add" crashes in the presence of a replacing
vdev with a spare child
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: asom...@freebsd.org
If a pool contains a replacing vdev with a spare child, then any "zpool add"
command will fail. It doesn't matter whether you're adding a regular vdev,
log, cache, or spare vdev. The bug is in get_replication in zpool_vdev.c in
the zpool command.
