/etc/fstab problem
 

Hello,

I've successfully set up a Win32 /Redhat dual boot situation here at the office.

Using the
#mkdir /mnt/data
#mount /dev/sda5 /mnt/data

I am manually able to mount the Fat32 partition.

When I update the /etc/fstab
with an appropriate /dev/sda5 line and
run a manual
#mount /mnt/data
I am successfully able to mount the Fat32 partition.

However, when I reboot, the reboot
somehow blows away the line I just appended in /etc/fstab
and the /mnt/data directory disappears.

What's going on? How can I remedy this problem?

Thanks.

P.S.
 

The version of Redhat is 7.3

that sounds really wierd. Are you sure that you saved your /etc/fstab? do:

cat /etc/fstab

and post that here.

the /mnt/data directory DISAPPEARS? that shouldn't happen do

ls /mnt

and see if it's there. You also might need to be doing this:

mount -t vfat /dev/scda5 /mnt/data

and a line like this in /etc/fstab :

/dev/scda5 /mnt/data vfat defaults 0 0

I don't know... that's all I can think of.

good luck

New fstab problem
 

I figured out that if "kudzu" is included anywhere on the /dev/sda5 options, kudzu for whatever reason wipes out
/mnt/data and erases the /dev/sda5 line in our /etc/fstab.

Our /etc/fstab line now
reads:
/dev/sda5 /mnt/data vfat defaults,uid=500,gid=100 0 0

Is there any way we can do a
uid=*,gid=*

or open up the /mnt/data to a multitude of uids (e.g. uid=500-700)? It's kind of a pain to manually enter all UIDs in. I tried simply setting
gid=100

but then the user with uid=500 no longer had access.

Thanks.

Do you want everyone on earth (or at least with an account with access to that computer) to have access to that directory? IF so, remove uid and gid and place:
umask=000

Instead.

Cool

How about...
 

That sounds like a nice workaround.

How about allowing just a single group, say the users
group (GID=500) to be able to access /mnt/data? How would I go about doing that?

I don't know how to use fstab for that, but you can do this:

chown -R :500 /mnt/data

and make sure that it has group read/write .... whatever you want


ooh... I forgot it's a vfat partition.... I'm not sure if that'll work, but you can try

good luck

Re: How about...
 

What umask does is basically set the chmod. SO a umask of 000 (umask=000) sets a chmod of 777 which means everyone and their dog has all permissions.

So a better way of putting this (and quoting from Acid):
from this thread: http://www.linuxquestions.org/questi...threadid=25234

You want to allow full group access, but no one else :
umask=007

What this will set is:
user full perm
group full perm
world (everyone else) no perm

And chown user:group /path/to/folder

This should, I believe set the correct values and abilities for that.

Cool
