I am trying to resize a filesystem after lvextend. ext2online returns the following; [root@netman root]# ext2online /dev/vg1/vol_usr ext2online v1.1.14 - 1999/10/14 for EXT2FS 0.5b ext2online: resizing to 258048 blocks ext2online: resize failed while in kernel ext2online: Invalid argument The ext2online man page states; In order to use ext2online, you need to have the Online ext2 resize support (CONFIG_EXT2_RESIZE) compiled into the kernel (this is an optional patch for the 2.x series of kernels). How do I tell if my kernel is properly compiled? If it is not properly compiled, I have a problem as I currently do not have the disk space to install gcc, make or the kernel source.
