From 515e555a0c36ae0294d71ba9ba45f7fa576cfd0f Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sun, 16 Oct 2011 19:29:40 -0400 Subject: [PATCH] resize2fs: don't fail when shrinking an empty file system This commit fixes a failure when running the commands: dd if=/dev/zero of=fs bs=1k count=100k; mke2fs fs; resize2fs -Mp fs We should not try truncating the file system if there is only a single block group in the file system.
