freebsd 8.2 stable as of july 16th
zpool version 28
zfs version 3
>Description:
trying to cd up one level using 'cd ..' gives permission denied
>How-To-Repeat:
use sh or tcsh, not bash...
$ pwd
/home/mharo
$ cd ..
cd: can't cd to ..
$ ls -ald /home
drwxr-xr-x 4 root wheel 4 Nov 29 2009 /home
$ ls -ald /home/mharo
drwxr-xr-x 3 mharo users 15 Jul 20 22:49 /home/mharo
$ cd /home
$ pwd
/home
$ ls -ald mharo
drwxr-xr-x 3 mharo users 15 Jul 20 22:49 mharo
$ cd mharo
$ cd ..
cd: can't cd to ..
so obviously I can cd into /home, just not via ..
$ zfs list -r zroot/home
NAME USED AVAIL REFER MOUNTPOINT
zroot/home 162K 2.70G 26K /home
zroot/home/mharo 119K 2.70G 35.5K /home/mharo
$ zpool get version zroot
NAME PROPERTY VALUE SOURCE
zroot version 28 default
$ zfs get version zroot/home
NAME PROPERTY VALUE SOURCE
zroot/home version 3 -
$ zfs get version zroot/home/mharo
NAME PROPERTY VALUE SOURCE
zroot/home/mharo version 3 -
I don't recall seeing this problem before I upgraded from zpool version 15 and
a 8-stable from january, but that doesn't mean it didn't exist.
