I haven't at ReiserFS in a year or so, but last I checked, you could expand a filesystem online, but shrinking online one was not possible if that is of importance to the original poster. You can shrink it offline however. http://www.namesys.com/resize_reiserfs.html#EXAMPLES According to the docs, that information is still current about reiserfs. For JFS: http://www10.software.ibm.com/developer/opensource/cvs/jfs/linux24/Documentation/filesystems/jfs.txt?rev=1.20&content-type=text According to this, the current JFS only supports expanding, which I (which is should do while online). However, it doesn't appear to support shrinking it at all. Now about ext2: There is a project on sourceforge for the ext2 resizing: http://ext2resize.sourceforge.net/download.html Here's a post by the author to in in the LVM mailing archive: http://linux.msede.com/lvm_mlist/archive/1999/07/0055.html (I've seen him post about it a lot more recently then that). Here's a page that appears to have some explaination about it: http://www-mddsp.enel.ucalgary.ca/People/adilger/online-ext2/ I have no idea how current they all are, I just googled for the ext2 resize online, plenty of links. Last I knew they don't support ext3, but they wanted to do that. It used to take a kernel patch to use it. I'm not sure if it still does.
