Hi,
Is it expected that if I have filesystem tank/foo and tank/foo/bar
(mounted under /tank) then in order to be able to browse via
/net down into tank/foo/bar I need to have group/other permissions
on /tank/foo open?
# zfs create tank/foo
# zfs create tank/foo/bar
# chown gavinm /tank/foo /tank/foo/bar
# zfs set sharenfs=rw tank/foo
# ls -laR /tank/foo
/tank/foo:
total 9
drwxr-xr-x 3 gavinm sys 3 Apr 24 00:24 .
drwxr-xr-x 9 root sys 9 Apr 24 00:23 ..
drwxr-xr-x 2 gavinm sys 2 Apr 24 00:24 bar
/tank/foo/bar:
total 6
drwxr-xr-x 2 gavinm sys 2 Apr 24 00:24 .
drwxr-xr-x 3 gavinm sys 3 Apr 24 00:24 ..
Note that the perms on /tank/foo are 755 at this point. Now
browse via /net down to the 'bar' level from some nfs client:
([EMAIL PROTECTED]:~ )-> cd /net/TB3.UK.SUN.COM
([EMAIL PROTECTED]:/net/TB3.UK.SUN.COM )-> cd tank/foo
([EMAIL PROTECTED]:/net/TB3.UK.SUN.COM/tank/foo )-> df -h .
Filesystem size used avail capacity Mounted on
TB3.UK.SUN.COM:/tank/foo
401G 25K 401G 1% /net/TB3.UK.SUN.COM/tank/foo
([EMAIL PROTECTED]:/net/TB3.UK.SUN.COM/tank/foo )-> cd bar
([EMAIL PROTECTED]:/net/TB3.UK.SUN.COM/tank/foo/bar )-> df -h .
Filesystem size used avail capacity Mounted on
TB3.UK.SUN.COM:/tank/foo/bar
401G 24K 401G 1%
/net/TB3.UK.SUN.COM/tank/foo/bar
So I am, as expected, in the tank/foo/bar filesystem.
But now change permissions on /tank/foo so that only I can access it:
# chmod 700 /tank/foo
# ls -laR /tank/foo
/tank/foo:
total 9
drwx------ 3 gavinm sys 3 Apr 24 00:24 .
drwxr-xr-x 9 root sys 9 Apr 24 00:23 ..
drwxr-xr-x 2 gavinm sys 2 Apr 24 00:24 bar
/tank/foo/bar:
total 6
drwxr-xr-x 2 gavinm sys 2 Apr 24 00:24 .
drwx------ 3 gavinm sys 3 Apr 24 00:24 ..
And now I cannot browse into filesystem tank/foo/bar, only into
the mountpoint directory (different capitalisation below to
trigger new automounts under /net):
([EMAIL PROTECTED]:/net/TB3.UK.SUN.COM/tank/foo/bar )-> cd /net/TB3.uk.SUN.COM
([EMAIL PROTECTED]:/net/TB3.uk.SUN.COM )-> cd tank/foo
([EMAIL PROTECTED]:/net/TB3.uk.SUN.COM/tank/foo/bar )-> df -h .
Filesystem size used avail capacity Mounted on
TB3.uk.SUN.COM:/tank/foo
401G 25K 401G 1% /net/TB3.uk.SUN.COM/tank/foo
Thanks
Gavin
