Set the mount option for new file systems

When you create a file system using SMITTY, the default action is for the file system NOT to mount after a reboot.
Now it might occur to you that generally when you create a file system, you probably want it to be available after a reboot. So you naturally hit the F4 key (or Esc 4 or just the Tab key) so that you can set the option to True.
Here's what to do if you've forgotten that option and found your file system hasn't mounted after a reboot.
From the command line:
The fix is quite easy using the chfs command, and you don't need to edit /etc/filesystems. Here's some relevant information taken from the command documentation for the chfs command
So for a single file system to mount automatically after a reboot, you'd run:
In our example above, that would be:
Fix the lot of 'em
What if you create a few file systems at a time, and have overlooked this mount = true option? Simple! Just run the chfs command for all file systems in a volume group.
You can list all the file systems in a volume group using the very simple and elegant lsvgfs command.
Update using xargs
Or, even better, as a reader suggested, use xargs.
Now you can reboot, or simply run mount -a. This will attempt to mount all file systems with the true mount attribute set in /etc/filesystems. What about those which are already mounted? You'll get an error telling you not to try to mount them again. Ignore it.
