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

Question

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?
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.

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)
