Bug ID: 225200
Summary: "zfs promote" of a zvol doesn't rename device nodes
for snapshots
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs at FreeBSD.org
Reporter: asomers at FreeBSD.org
A "zfs promote" operation renames the snapshot that was the basis for the
cloned dataset. If that dataset is a zvol, then the snapshot has an associated
device node. That device node should be renamed by "zfs promote", but it
doesn't.
Steps to reproduce:
[alans at tom ~]$ sudo zpool create -f foo da1
[alans at tom ~]$ sudo zfs create -V 100m foo/vol0
[alans at tom ~]$ sudo zfs snapshot foo/vol0 at snap
[alans at tom ~]$ sudo zfs clone foo/vol0 at snap foo/vol1
[alans at tom ~]$ ls -l /dev/zvol/foo/
total 0
crw-r----- 1 root operator 0x85 Jan 15 17:24 vol0
crw-r----- 1 root operator 0x130 Jan 15 17:24 vol0 at snap
crw-r----- 1 root operator 0x131 Jan 15 17:24 vol1
[alans at tom ~]$ sudo zfs promote foo/vol1
[alans at tom ~]$ ls -l /dev/zvol/foo/
total 0
crw-r----- 1 root operator 0x85 Jan 15 17:24 vol0
crw-r----- 1 root operator 0x130 Jan 15 17:24 vol0 at snap
crw-r----- 1 root operator 0x131 Jan 15 17:24 vol1
The "vol0 at snap" node should've been renamed to "vol1 at snap". After a reboot, it
does get the correct name.
