If y= ou 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 snapsho= t 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 . --=20 You are receiving this mail because: You are the assignee for the bug.=
