hello all,
I am trying to expand my /var file system which resides on a logical volume. <snip>
ext2online: unable to resize /dev/mapper/root_vg-lv_var

3 Error in pre-resizing (user space) operation
Can someone tell me what I'm doing wrong. I would prefer doing this online...
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?
I just checked the stock kernel (34-2 version) .config file and that flag is not enabled, AFAICT. Maybe the Plus kernel has it?
I know that online ext3 resize works just fine on c-4, I've resized many (including our centos-mirror and a few multi-terabyte filesystems with load).
What the OP could be hitting is trying to resize an old or somehow broken fs. I'd have a look at "tune2fs -l" for the filesystem.
