Mount Command help

Hi there,

I have RHEL 4, I am trying to mount a partion with ACL enabled.

I have a partion /dev/hdb1 , I need to mount this to a folder name /volume with ext3, rw, acl.

what is the command to do this.

Do i have to modify the /etc/fstab ?

Help please

$ man -P cat mount | grep -C 10 -i acl
       None.   Note  that  the  `ext'  file  system is obsolete. Don't use it.
       Since Linux version 2.1.21 extfs  is  no  longer  part  of  the  kernel

Mount options for ext2
       The  `ext2' file system is the standard Linux file system.  Since Linux
       2.5.46, for most  mount  options  the  default  is  determined  by  the
       filesystem superblock. Set them with tune2fs(8).

       acl / noacl
              Support POSIX Access Control Lists (or not).

       bsddf / minixdf
              Set  the  behaviour  for  the  statfs  system  call. The minixdf
              behaviour is to return in the f_blocks field the total number of
              blocks  of  the file system, while the bsddf behaviour (which is
              the default) is to subtract the overhead blocks used by the ext2
              file system and not available for file storage. Thus

       % mount /k -o minixdf; df /k; umount /k
Amazing how you can find things in the manual, huh? Anyways, I would guess "mount /dev/hdb1 -o acl", but I'm not sure.

This is excerpted from the RHEL 3 sysadmin-guide:
Alternatively, if the partition is listed in the /etc/fstab file, the entry for the partition can include the acl option:

LABEL=/work /work ext3 acl 1 2

If an ext3 file system is accessed via Samba and ACLs have been enabled for it, the ACLs are recognized because Samba has been compiled with the --with-acl-support option. No special flags are required when accessing or mounting a Samba share.
If you want to mount it manually:
mount -t ext3 <device-name> <partition> -o acl

These things are listed in your manual and the "man mount" manpage.
