If that dataset is a zvol, then the snapshot has an associ= ated device node. That device node should be renamed by "zfs promote", but it doesn't. Steps to reproduce: [alans@tom ~]$ sudo zpool create -f foo da1 [alans@tom ~]$ sudo zfs create -V 100m foo/vol0 [alans@tom ~]$ sudo zfs snapshot foo/vol0@snap [alans@tom ~]$ sudo zfs clone foo/vol0@snap foo/vol1 [alans@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@snap crw-r----- 1 root operator 0x131 Jan 15 17:24 vol1 [alans@tom ~]$ sudo zfs promote foo/vol1 [alans@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@snap crw-r----- 1 root operator 0x131 Jan 15 17:24 vol1 The "vol0@snap" node should've been renamed to "vol1@snap". After a reboot= , it does get the correct name. --=20 You are receiving this mail because: You are the assignee for the bug.=
