The Grumpy Geek

Today I needed to extend a logical volume in the native LVM of RHEL 5.  I remembered how to extend the volume but wanted to review the exact method for resizing the (ext3) filesystem on it.  All the documentation I could find including on RedHat’s knowledgebase indicated the command “ext2online” should be used (based on RHEL 4.)  No such command existed on the RHEL 5 system and I could find no official sources to install it.  I finally ran across this post indicating someone’s similar frustration that apparently RH changed the command to “resize2fs” without any warning.  With this information, I was able to do the resize in seconds.  Thanks RedHat.
