That's funny, since I can resize trivial-sized ext3 filesystems online with stock Debian 2.6 kernels, but not ext2's. This is the error message I get when trying to resize a 32MB ext2 filesystem to 64MB with ext2online: ext2online: resizing to 65536 blocks ...flushing buffer 9/block 57348 Calling mount() for /tmp/file(/tmp/test) with debug,check,resize=65536 ext2online: resize failed while in kernel ext2online: Invalid argument ext2online: does the kernel support online resizing? Same resize on ext3 works. Maybe this package should be renamed :) Now if it would only work on real-world sized filesystems. Apparently one can grow (but not shrink) file systems inside the 16 GB multiple (for a 4k blocksize) to which the fs was created on, but not more. ext2prepare gives errors of the type: ext2prepare: error reserving block 0xab8005 But this software seems to unmaintained both upstream and in Debian, so we're stuck with resize2fs.
