CentOS - Aug 2006 - extending ext3 filesystem on logical volume

hello all,

I am trying to expand my /var file system which resides on a logical 
volume. I successfully issued the lvextend command. However when I try 
to issue the ext2online command I receive a return code of 3 which the 
man pages indicates:

ext2online /var
ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b
ext2online: group 0, block 7 not reserved

ext2online: unable to resize /dev/mapper/root_vg-lv_var

echo $?
3

3    Error in pre-resizing (user space) operation

Can someone tell me what I'm doing wrong. I would prefer doing this 
online...

thanks,

James

I think it would be much safer to do it offline.
Online resizing only came to be in kernel 2.6.7 somewhere, and I haven't
seen
anything saying it was real safe yet.

You may not be doing anything wrong. From the man page,

  you need to have the Online ext2 resize support
  (CON-FIG_EXT2_RESIZE)  feature  enabled  in  the kernel (after
  applying the appropriate patch for the 2.x series of kernels).

*I* don't know if the kernel(s) have been compiled with this enabled? Do
you know?
