Bug ID: 225223
Summary: "zfs rename -r" of a snapshot doesn't rename zvol
snapshots' device nodes
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
ZFS creates device nodes for every zvol and every snapshot of a zvol. If you
rename a snapshot on a zvol, the device node will automatically get renamed
too. However, if you use "zfs rename -r" (-r means recursive) on a snapshot of
the zvol's parent dataset, then the snapshot's device node will _not_ get
renamed.
Steps to reproduce:
[alans@tom ~]$ sudo zpool create foo da1
[alans@tom ~]$ sudo zfs create -V 100m foo/vol0
[alans@tom ~]$ sudo zfs snapshot -r foo@0
[alans@tom ~]$ find /dev/zvol/foo/ -type c
/dev/zvol/foo/vol0
/dev/zvol/foo/vol0@0
[alans@tom ~]$ sudo zfs rename -r foo@0 foo@1
[alans@tom ~]$ find /dev/zvol/foo/ -type c
/dev/zvol/foo/vol0
/dev/zvol/foo/vol0@0
[alans@tom ~]$ zfs list -t all -r foo/vol0
NAME USED AVAIL REFER MOUNTPOINT
foo/vol0 105M 3.51T 56K -
foo/vol0@1 0 - 56K -
/dev/zvol/foo/vol0@0 should've been renamed to /dev/zvol/foo/vol0@1 .
