I'll admit I was unaware of that command. I notice that the third 
sentence of the man page says "It is only possible to enlarge a mounted 
filesystem". While Sean was indeed increasing the size, I was trying to 
reduce it.

A big pain with Linux, in my view, is that even after using it for six 
years, I am unaware of the majority of features available in it. I did 
what I thought was reasonable; I read the HOWTO (the one mentioned down 
there at the bottom of this email ;). No mention of ext2online there, 
nor any mention of the steps I used to resize a root filesystem; only 
the steps for a filesystem that can be easily unmounted while the OS is 

And in order to figure out the steps to resize the root filesystem, I 
read through a lot of man pages and web pages and howtos, and nowhere do 
I recall coming across ext2online (though I'll admit that was awhile 
ago). By the way, I suggested in my posting that the steps be added to 
the howto (the subject line was "Howto suggestion..."). And I have seen 
other postings here with suggestions about the howto.
