How can I mount ext3 with restricted permissions, like setting uid, gid and umask?

up vote 0 down vote favorite

I want to mount an ext3 filesystem on a device with uid, gid, umask options set. When I use these options during mount, I get an error.

Below is the command I am using to mount:

mount -t ext3 -o uid=1001, gid=1001, umask=0066 /dev/mapper/mdev5 /dir

Is there any alternate to do so using mount?

	Why do you think `umask` is an option you can set with `ext3` filesystems? – sarnold Nov 16 '11 at 11:29
	Check the allowable mount options for ext3 in your mount man page. As far as I'm aware, `umask` is not available for `ext3`, and from a brief reading I'm not sure `uid` and `gid` are either. – drfrogsplat Mar 27 at 6:08

Read manpage for mount command. It says,

-o, --options opts Options are specified with a -o flag followed by a comma separated string of options

so, your command should be,

mount -t ext3 -ouid=1001,gid=1001,umask=0066 /dev/mapper/mdev5 /dir

(without space between options)
